The following map shows the average monthly precipitation in the western United States. The areas in dark blue have very high amounts of precipitation and the areas in orange have very low amounts of precipitation. Image courtesy of USGS Why is there so much more precipitation near the coast than in other areas?
A. It is close to the ocean, and moisture from the air above the ocean moves eastward to the coast where the precipitation often occurs.
B. The water near the northwest does not produce enough moisture for winds to carry it to the rest of the area.
C. The water near the coast does not get heated enough to cause precipitation in the rest of the area.
D. The land and the water have different temperatures, so warm fronts and cold fronts constantly exist above the coast.

Answers

Answer:

Its B

Explanation:

There is so much more precipitation near the coast than in other areas as the water near the northwest does not produce enough moisture for winds to carry it to the rest of the area. Therefore, option (B) is correct.

Why is precipitation is more in coastal areas?

Due to the high humidity of the clouds near the coast, coasts receive more precipitation than interior continents. They have already shed water in the form of rain when they reach the interior of the continents, so there is not much humidity left to cause rain.

Southeast Asia's monsoon region and the equatorial zone receive the most precipitation. Center scopes get moderate measures of precipitation, yet little falls in the desert locales of the subtropics and around the shafts.

The Northeast monsoons, which draw moisture from the Bay of Bengal, are responsible for the majority of the rain that falls on the Coromandel coast during the winter.

Please someone answer I need help.

Answers

Answer: The Low Pressure systems will usually be found more North where it gets verycold but can really happen anywhere, and High pressure systems are usually found in the Southwest during winter.

Explanation:

High Pressure:

A high pressure system has higher pressure at its center than the areas around it. Winds blow away from high pressure. Swirling in the opposite direction from a low pressure system, the winds of a high pressure system rotate clockwise north of the equator and counterclockwise south of the equator. This is called anticyclonic flow. Air from higher in the atmosphere sinks down to fill the space left as air is blown outward. On a weather map, you may notice a blue H, denoting the location of a high pressure system.

Low Pressure:

A low pressure system has lower pressure at its center than the areas around it. Winds blow towards the low pressure, and the air rises in the atmosphere where they meet. As the air rises, the water vapor within it condenses, forming clouds and often precipitation. Because of Earth’s spin and the Coriolis effect, winds of a low pressure system swirl counterclockwise north of the equator and clockwise south of the equator. This is called cyclonic flow. On weather maps, a low pressure system is labeled with red L.

Why it was important that Gregor Mendel used thousands of pea plants in his experiments? Would Mendel have found the same results if he had used only twenty plants? Explain.

Answers

Answer:

Explanation:

Gregor Mendel used thousands of pea plants in his experiments to ensure that his results were accurate and reliable. By using a large sample size, he was able to reduce the effects of chance and random variation in his experiments. This is important because biological systems are complex and variable, and small sample sizes can lead to inaccurate or misleading results.

Mendel's experiments involved crossing pea plants with different traits (e.g., tall vs. short, yellow vs. green), and he counted the number of offspring with each trait. He found that the offspring followed predictable patterns of inheritance, which he summarized in his laws of inheritance.

If Mendel had used only twenty plants in his experiments, he may not have obtained the same results. With a small sample size, chance events can have a greater impact on the results. For example, if he crossed two pea plants with different traits and obtained only a few offspring, it's possible that chance events (such as mutations or environmental factors) could have influenced the results. This could lead to false conclusions about the inheritance of the traits.

Therefore, using a large sample size was critical to Mendel's success in developing his laws of inheritance. It allowed him to detect patterns that were consistent across many different crosses, and to demonstrate that these patterns were not the result of chance variation.

These are plants that always produce offspring that look like the parent. By experimenting with true-breeding pea plants, Mendel avoided the appearance of unexpected traits in offspring that might occur if the plants were not true breeding.

In three paragraphs, explain the difference between gills and lungs. Give examples of animals with only gills, those with only lungs, and those with both gills and lungs. What are the advantages of having gills, lungs, and both?
HELP ASAP!!!!

Answers

Gills are for fish and salamanders lungs are for mammals and such like that
The main difference between gills and lungs is that gills are the type of respiratory organs specialized to breathe in water, whereas lungs are the type of respiratory organs specialized to breathe in the air. Furthermore, fish use gills while mostly tetrapods use lungs.
Lungfish have a unique respiratory system, having both gills and a lung. It is the only type of fish to have both organs, not only does it help them to survive, but may also be key to the evolutionary origins of the lung. Granddad is the oldest fish we know of anywhere in the world, and there are only six known species around the world.
The advantages of having both lungs and gills gives a better chance of survival above and in water.

What best describes ribosomes?

Answers

Ribosomes are cellular structures that synthesize proteins from amino acids. They are composed of ribosomal RNA and proteins and are found in both prokaryotic and eukaryotic cells.

Ribosomes are essential for gene expression and cell growth. They can be free in the cytoplasm or bound to the endoplasmic reticulum or the nuclear envelope.

An example of a ribosome function is the translation of a messenger RNA (mRNA) sequence into a polypeptide chain. The ribosome reads the mRNA codons and matchesthem with the corresponding transfer RNA (tRNA) anticodons that carry the amino acids. The ribosome then forms a peptide bond between the amino acids and releases the tRNA. This process continues until the ribosome reaches a stop codon on the mRNA and terminates the protein synthesis.

Answer:

A ribosome is a  intercellular  structure made of RNA and protein

It is theorized that the continents on Earth were once joined together,
forming a supercontinent called Pangaea. How long ago did Pangaea
exist? How were the continents of Africa and South America arranged in
relation to each other? Describe one piece of evidence to support their
relationship. Write your response in complete sentences

Answers

Answer:

Pangea existed many millions of years ago in many opinions, but it started back in the late Paleozoic Era until the very late Triassic. Pangea first began to be torn apart when a three-pronged fissure grew between Africa, South America, and North America. Scientists have found fossils of similar types of plants and animals in rocks of similar age. These rocks were on the shores of different continents. This suggests that the continents were once joined. For example, fossils of Mesosaurus, a freshwater reptile, have been found both in Brazil and western Africa.

Explanation:

Answer:

Pangaea is believed to have existed around 335 million years ago during the late Paleozoic and early Mesozoic eras.

During this time, the continents of Africa and South America were joined together as part of the supercontinent Pangaea. They were located in the southern hemisphere, with Africa to the east and South America to the west.

One piece of evidence to support their relationship is the similarity of plant and animal fossils found on both continents. Fossils of the ancient reptile Mesosaurus have been found in both Africa and South America, indicating that the two land masses were once connected. The distribution of fossils of other plant and animal species also suggests that Africa and South America were once part of the same landmass.

The theory of Pangaea and continental drift was first proposed by Alfred Wegener in the early 20th century, and it has since been supported by a range of geological and paleontological evidence. The movement of the continents has had a profound impact on the evolution of life on Earth, as it has created new habitats and allowed for the evolution of new species in isolation.

What structures (Homologous, Analogous, or Vestigial) would be most helpful in studying the selective pressures in an environment. Explain.

Answers

Answer:

In studying selective pressures in an environment, homologous structures would be the most helpful to analyze. Homologous structures are structures that have similar anatomy and structure but may have different functions, and they are thought to have evolved from a common ancestor.

Comparing homologous structures among different species can provide insight into how different organisms have adapted to their environments over time. By analyzing the similarities and differences in these structures, scientists can learn about the evolutionary history of a group of organisms and the selective pressures that have influenced their evolution.

For example, the forelimbs of mammals are homologous structures that have different functions in different species. The forelimbs of humans, bats, and whales all have the same basic structure, with a humerus, radius, and ulna, as well as a set of bones that make up the wrist and hand. However, the functions of these forelimbs are very different: humans use their arms for grasping and manipulating objects, bats use their wings for flight, and whales use their flippers for swimming.

Studying these homologous structures can help scientists understand the selective pressures that have led to the evolution of these different functions. For example, the wings of bats and the flippers of whales are adaptations that have evolved in response to the need for flight or swimming, respectively. By studying the similarities and differences in these structures, scientists can gain insight into how these adaptations have evolved over time and the environmental pressures that have influenced their evolution.

Answer:

Explanation:

Homologous structures are physical structures such as organs or skeletal elements present in numerous species that come from a shared common ancestor. Analogous structures are bodily structures that resemble one another superficially and provide a similar function but have evolved separately and do not come from a shared common ancestor (such as the wings of an insect and bat).

One vestigial structure present in humans is the appendix. This organ was once vital in the consumption and digestion of uncooked meat, but no longer serves a function.

2. Fossil fuels are resources that are formed from the remains of dead plants and animals. An example would be coal, oil, and natural gas. These fuels are used to generate electricity, power vehicles, heat homes and buildings. Yes, there many other energy sources that can replace fossil fuels.

3. One way to prevent factories from dumping waste water in rivers and oceans is to implement stricter regulations and penalties for those who violate them.

4. One of the best ways to reduce the amount of garbage is to reduce, reuse, and recycle.

5. Yes, I drink bottled water because it's more water to drink from a bottle and its effect on the environment is recycling and being reused.

Answer
1. Pollution can be of many types such as air pollution, water pollution, noise pollution, and land pollution. In my opinion, air pollution is the worst because it affects people's health and can cause breathing problems, heart diseases, and even cancer. Discussing this issue in a group can help us understand different perspectives and find solutions to reduce pollution.

2. Fossil fuels are non-renewable sources of energy that are formed from the remains of dead plants and animals. Examples of fossil fuels include coal, oil, and natural gas. They are used to generate electricity, fuel vehicles, and heat homes. However, they are a major contributor to air pollution and climate change. Fossil fuels can be replaced by renewable sources of energy such as solar, wind, and hydro power.

3. Factories dumping waste water in rivers and oceans can have a negative impact on aquatic life and the environment. To prevent this, factories can treat their waste water before discharging it into the environment. Governments can also enforce strict regulations and penalties for factories that violate environmental laws.

4. To reduce the amount of garbage, we can follow the three R's - reduce, reuse, and recycle. We can reduce the amount of waste we generate by using reusable bags, bottles, and containers. We can also compost organic waste such as food scraps and yard waste. Recycling can also help reduce the amount of garbage by turning waste into new products.

5. I try to avoid drinking bottled water because it generates a lot of plastic waste that can take hundreds of years to decompose. Plastic waste can also harm wildlife and pollute the oceans. Instead, I use a refillable water bottle and fill it with tap water. Tap water is safe to drink in most developed countries and can be a more sustainable choice.

State the functions of the skeletal system, including the number and the major bones in the human skeleton.

Answers

The skeletal system serves several important functions in the human body. These functions include:

1. Support: The skeleton provides the structural framework for the body, giving support and shape to the organism.

2. Protection: The skeletal system protects vital organs such as the brain, spinal cord, heart, and lungs. For example, the skull protects the brain, the ribcage protects the heart and lungs, and the vertebrae protect the spinal cord.

3. Movement: Bones act as levers for muscles, enabling body movement. The skeletal system works in conjunction with the muscular system to facilitate motion.

4. Mineral storage: Bones store essential minerals, such as calcium and phosphorus, which are necessary for various body functions.

5. Blood cell production: Red and white blood cells, as well as platelets, are produced in the bone marrow, which is found in some bones.

6. Energy storage: Yellow bone marrow, found in the medullary cavity of long bones, stores energy in the form of fat.

The human skeleton consists of 206 bones in adults. Some of the major bones include:

1. Skull: Comprised of the cranium and facial bones, it protects the brain and supports the structures of the head.

2. Spine (vertebral column): Consists of 33 vertebrae, which protect the spinal cord and support the upper body.

3. Ribcage: Includes 12 pairs of ribs, the sternum, and the thoracic vertebrae, which protect the heart and lungs.

4. Humerus: The long bone in the upper arm, connecting the shoulder to the elbow.

5. Radius and Ulna: The two bones in the forearm, connecting the elbow to the wrist.

6. Femur: The long bone in the thigh, connecting the hip to the knee, and is the longest bone in the body.

7. Tibia and Fibula: The two bones in the lower leg, connecting the knee to the ankle.

8. Pelvis: A basin-shaped structure that supports the spine and organs of the lower abdomen, and connects the spine to the lower limbs.

These are just a few examples of the major bones in the human skeleton.

Answer:

Explanation:skeletal system functions are diffrent of types . In addition to defining our shape and traits as humans, it:

enables movement: Your skeleton helps you stand and move by supporting your weight. Your bodily components are movable thanks to the cooperation of joints, connective tissue, and muscles.

Bone marrow, which makes blood cells, is found in bones. The bone marrow makes RBC AND WBC

supports and shields organs: Your ribs shield your heart and lungs, your backbone shields your spine, and your skull shields your brain.

Mineral storage: Your bones are where your body stores minerals like calcium and vitamin D.
