While savannas and temperate grasslands are both types of
grasslands and share many characteristics, they also have
some differences. Compare them below by writing each
characteristic in the correct location. You will use each only
once.
• home to many types of grazers
• experience all seasons of weather
• home to bison
• home to the African elephant
• example: tallgrass prairies of North America
• example: Serengeti in Tanzania
• also known as tropical grasslands
• few trees due to little rainfall
1)
(Savannas)
(Both Types of
Grasslands)
(Temperate
Grasslands)
Answers
Answer:
S - Savannas are typically found in tropical or subtropical regions.
S - Savannas tend to have more trees and shrubs.
S - Savanna's climate is drier than that of a grassland.
G - Grasslands are found in temperature regions.
G - Temperature Grasslands are mainly devoid of trees, receive less rainfall than Savannas & endure broader temperature extremes.
G - Grasslands make up 25 percent of the Earth's land surface and dominate in regions with limited rainfall, which prevents forest growth. This results from nearby mountain ranges that cause rain shadows over adjacent open-range lands.
B - Both represent the world's richest and most diverse ecosystems. They both provide a home for a quarter of the world's population and a habitat for thousands of plants and animals.
B - Many species gather in vast numbers, graze on the varied grasses, and can be found nowhere else on Earth. The coexistence between wildlife and grasses is key to healthy ecosystems. Animal migrations regenerate the landscapes, by controlling pests, dispersing seeds, and trampling invasive species. Through this partnership, grasslands and savannahs generate vital benefits for both people and nature.
B - Ecosystems such as these two in specific are essential for climate mitigation – they store carbon, locking it deep in the soil and extensive root systems. They are the source of or support many of the world’s biggest rivers and wetlands, ensure food security, support livelihoods, and are embedded in the cultural identity of millions of people.

Too much sodium in the diet can lead to high blood pressure, heart disease, and stroke. It can also cause calcium losses, some of which may be pulled from bone. Hyponatremia is a condition characterized by low levels of sodium in the blood. Its symptoms are similar to those caused by dehydration. In severe cases, the brain may swell, which can lead to headaches, seizures, coma, and even death.

Why do you think the Arecibo message and the beacon in the Galaxy were broadcast in binary code?
Answers
Answer:
Hi!
The Arecibo message and the beacon in the galaxy were broadcast in binary code because binary is a universal language that can be easily understood by any intelligent beings, regardless of their language or culture. Binary code consists of only two symbols, 0 and 1, which can be used to represent any information, including letters, numbers, and instructions. This makes binary an ideal choice for transmitting messages over vast distances, as it is less prone to errors and can be decoded with a high degree of accuracy.
Oxygen and CO2 are exchanged between capillaries and alveolus. Do capillaries contain deoxygenated blood while alveolous contains oxygenated blood?
Answers
In other words, alveolus does not have oxygenated blood it just puts oxygen into the deoxygenated blood hat this brought in.
Answer:
this is answer
Explanation:
The aveolus is surrounded by capillaries. So capillaries carry deoxygenated blood to the alveolus where the oxygen from the alveolus diffuses into the blood in the capillaries. The deoxygenated blood is now oxygenated and is carried out of the lung via capillaries that then merge into the pulmonary vein.
In other words, alveolus does not have oxygenated blood it just puts oxygen into the deoxygenated blood hat this brought in.

to grow
to make sperm and egg cells for reproduction
to heal
to replace dead cells
Answers
Answer:
to heal..
Explanation:
Answer: To make sperm and egg cells for reproduction
Explanation:
Cell division happens in humans and most other animals by mitosis and meiosis. When a cell divides by way of mitosis, it produces two clones of itself, each with the same number of chromosomes. When a cell divides through meiosis, it produces four cells, called gametes. Gametes are also called sperm in males and eggs in females.
Unlike in mitosis, the gametes produced by meiosis are not clones of the original cell, because each gamete has exactly half as many chromosomes as the original cell.
In healing and growth, mitosis occurs beacuse the body clones cells to produce more of the exact same kind of that body part.

5. Do you drink bottled water? Why or why not? What is its effect on the environment?
pls 3-5 sentence and then explain briefly the answer. ty
Answers
Answer:
1. There's air pollution, water pollution, noise pollution, and light pollution. The worst pollution is air pollution because it can cause severe health problems like respiratory diseases or even cancer.
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.
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.

compare and contrast hormonal regulation during pregnancy and hormonal regulation during the menstrual cycle.
Answers
Answer: In summary, hormonal regulation during pregnancy and the menstrual cycle share some similarities, but differ in their goals, hormones involved, hormonal feedback loops, and timing.
Explanation: Hormonal regulation during pregnancy and the menstrual cycle are both complex processes involving several hormones, but they differ in their overall goals and mechanisms. Here are some key differences:
Goals: The primary goal of hormonal regulation during pregnancy is to maintain the pregnancy and support the growth and development of the fetus. In contrast, the primary goal of hormonal regulation during the menstrual cycle is to prepare the body for a possible pregnancy.
Hormones involved: Both processes involve the hormones estrogen and progesterone, but the levels and roles of these hormones are different. During pregnancy, the placenta produces high levels of estrogen and progesterone, which help maintain the pregnancy and prepare the body for childbirth. During the menstrual cycle, estrogen and progesterone are produced by the ovaries, and their levels fluctuate throughout the cycle.
Hormonal feedback loops: Hormonal regulation during pregnancy involves a positive feedback loop, in which rising levels of hormones signal the body to produce even more hormones to maintain the pregnancy. In contrast, hormonal regulation during the menstrual cycle involves a negative feedback loop, in which rising levels of hormones signal the body to reduce hormone production.
Timing: Hormonal regulation during pregnancy is a continuous process that lasts for nine months, while hormonal regulation during the menstrual cycle occurs on a monthly basis.
The main hormones involved and the general goals of hormonal management during pregnancy and the menstrual cycle are different.
Pregnancy: Human chorionic gonadotropin (hCG), a hormone generated by the placenta, is the main hormone involved in pregnancy. Hormonal control during pregnancy serves to support the foetus' growth and development, preserve the uterine lining, and stop menstruation. Progesterone and oestrogen, among other hormones, are essential in sustaining pregnancy because they help the foetus develop and prepare the body for childbirth.
Menstrual Cycle: Hormones such follicle-stimulating hormone (FSH), luteinizing hormone (LH), oestrogen, and progesterone control the menstrual cycle. Menstruation, the follicular phase, ovulation, and the luteal phase are some of the various phases that make up the cycle. Hormonal control during the menstrual cycle serves to prime the uterus for prospective implantation and fertilisation. Throughout the cycle, levels of oestrogen and progesterone rise and fall, affecting the uterine lining's thickening and shedding.

Every compound can be represented by a chemical formula. A chemical formula is the set of symbols showing the elements that make up a compound and their proportions. Water’s chemical formula is H_2 2 O. That means a molecule of water contains two atoms of hydrogen and one atom of oxygen chemically bonded. A molecule is a group of two or more atoms bonded together. Molecules can range in size from two to thousands of atoms. A molecule of a compound is the smallest unit of that compound. Every molecule of water has all the physical and chemical properties of water. That’s because every molecule of water is made of the same elements in the same proportions: two hydrogen atoms and one oxygen! Which of the following is a true statement?
A
Every molecule of the same compound will have different properties.
B
Every molecule of a compound has the same proportion of elements.
C
Molecules can be physically separated into smaller units of a compound.

Answers
Answer: Respiration inhales oxygen gases and exhales carbon dioxide.
Explanation: Here, Oxygen enters the blood during inhalation, and carbon dioxide leaves during exhalation. This process is called Respiration. Air enters through the nose or mouth and goes through the nostrils, then the pharynx where two tubes are seen one for food and the other for air. From there it goes to the larynx, the voice box. Next air travels to the trachea(the windpipe) from which they get divided into left and right air tubes called bronchi. Smaller bronchi are called bronchioles. These end in tiny air sacs called alveoli. Exchange of gases takes place and revert back.
