Mosquitoes can have bigger or smaller body sizes. Two parents that have medium-sized bodies have offspring. One of their offspring has a small body, and one has a large body. How did the offspring end up with traits that are different from the traits of their parents? How did the gene combinations result in these traits?

Here is a possible chat between the hypothalamus and the pineal gland before sleep:

The hormone that the hypothalamus produces that sends signals to the pineal gland to produce melatonin is called melatonin-releasing hormone (MSH). The hypothalamus and the pineal gland work together to regulate sleep-wake cycle.

When it gets dark outside, the hypothalamus releases MSH, which signals the pineal gland to start producing melatonin. Melatonin is a hormone that makes the body feel sleepy. It helps to regulate the body's internal clock and to promote sleep.

Answer: Encourage students to set up a germination experiment by placing the seeds in different conditions, such as light vs. dark, or wet vs. dry. Moreover, they need to pot the same seed in more than one pot.

Explanation:

This option provides a clear and practical approach to the seed germination investigation. By setting up different conditions for the seeds, such as light vs. dark or wet vs. dry, the students can observe and compare how these conditions affect the germination process. Additionally, potting the same seed in multiple pots allows for a controlled comparison within the experiment.

By manipulating these variables, the students can gather valuable data and observations regarding the influence of light and moisture on seed germination. This approach promotes a hands-on and investigative learning experience, encouraging students to actively engage with the scientific process while documenting the changes that occur over time, such as the emergence of roots and shoots.

Explanation:

Plants need chlorophyll to make food.

Because,

Animal cells can't make their own food

And photosynthesis never happen in animal cells

Answer:

Protons are found in the: nucleus

The number of protons determines: the identity of the atom/the element

The number of protons is called: the atomic number

Where you look to find the number of protons: periodic table(ex. boron is 5, barium 56, actinium 89, neon 10)

Protons are charged: positive charge

Neutrons are found in the: nucleus

Neutrons are charged: neutral(no charge)

They help protons by: stabilizing their repulsive charge(same charge repels) and stabilizing the nucleus

The mass of protons and neutrons are: 1 amu

Electrons mass is: 5.45 × 10^-4 amu(usually for practical purposes people just say it has 0 mass)

Electrons are charged: negatively

In a neutral atom: number of protons = number of electrons(net charge = 0)

Electrons are responsible for: keeping the atoms neutral, valence electrons interact with other atoms to form ionic compounds.

Explanation:

The geosphere refers to the land of the Earth.

The biosphere refers to all the living things on Earth.

The hydrosphere refers to all of the water in the Earth.

The atmosphere refers to the air on Earth.

To create a terrarium model, you could start by placing rocks all throughout the bottom of it. Pile up more on one side to create a hill. This represents the geosphere. Then, fill some of it with water. Make sure some of the rocks of that hill you made are still above the water, however. This represents the hydrosphere. Next, add a little plant or even a toy animal in to represent the biosphere. Finally, the remaining space represents the atmosphere, as humans can't see it so it's just clear.

The terrarium is a small, enclosed ecosystem that beautifully showcases the geosphere, biosphere, hydrosphere, and atmosphere in miniature form.

The geosphere is represented by the solid base of the terrarium, which mimics the Earth's crust and surface. Various rocks, pebbles, and soil are incorporated to depict the diverse landscapes found in the geosphere, such as mountains, valleys, and plains.

For the biosphere, added a selection of plants and small organisms. These living elements bring the terrarium to life, representing the complex interactions between flora and fauna found in the biosphere. Plants play a crucial role in converting carbon dioxide to oxygen through photosynthesis, simulating the vital connection between the biosphere and the atmosphere.

Next, the hydrosphere was depicted by a small, serene water feature within the terrarium. This mini aquatic environment captures the essence of Earth's oceans, rivers, and lakes, showcasing the interconnectedness of the hydrosphere with other systems. The water's presence also influences the microclimate, creating a more dynamic terrarium ecosystem.

Finally, the atmosphere is subtly indicated by the transparent walls of the terrarium, enclosing and safeguarding the entire model. This clear boundary represents the thin layer of gases surrounding Earth, providing protection and the right conditions for life to thrive within the terrarium's microcosm.

Thus, the combination of these different elements in the terrarium creates a harmonious representation of Earth's interconnected systems.

Explanation:

Answer:

It is neither a liquid nor solid.

Explanation:

Glass, however, is actually neither a liquid—supercooled or otherwise—nor a solid. It is an amorphous solid—a state somewhere between those two states of matter. And yet glass's liquidlike properties are not enough to explain the thicker-bottomed windows, because glass atoms move too slowly for changes to be visible.

Answer:

The benefits dams bring.

Explanation:

Dams are important because they provide water for domestic, industry and irrigation purposes. Focusing on the damage they do doesn't really help unless they are a major problem.

Earth's long-term warming trend can be seen in this visualization of NASA's global temperature record, which shows how the planet's temperatures are changing over time, compared to a baseline average from 1951 to 1980. The record is shown as a running five-year average.

Answer:

Producer is an organism that produces it's own food e.g. photosynthesis in plants. Also known as the base of the food-chain.

Consumer is an organism that consumes (eats) either a producer or another consumer e.g. animals will solely eat plants (herbivore) , sole animals (carnivore), or a combination of both (omnivore).

Decomposers are organisms that 'eat' and break up dying/decaying material e.g. earthworms and fungi.

Answer: producers create their own food, consumers eat the producers, and decomposers eat consumers after they die and provide fuel for new producers

The freshwater ecosystem (rivers, ponds, oceans) is more likely to have winter ice because it does not contain salts as in the marine ecosystem, which prevents the water to freeze.

Aquatic environments are the water contain environments. These environments include rivers, ponds, lakes, seas, oceans, etc. Aquatic environments contain aquatic animals like fishes, octopuses, frogs, crocodiles, etc.

Freshwater bodies freeze easily, and salt water bodies do not freeze easily because salt present in the water prevents it from freezing.

Thus, because freshwater ecosystems (rivers, ponds, and oceans) lack the salts found in marine ecosystems that keep the water from freezing, they are more prone to have winter ice.

Answer:

Horseshoe crabs are chelicerates, which means they're made of two segments, the cephalothorax and the abdomen. The cephalothorax is a fusion of the head (cephalon) and chest (thorax), and the tail is part of the abdomen. Trilobites, on the other hand, are composed of 3 parts, cephalon, thorax, and pygidium. In this body plan, the pygidium is the tail and is a separate segment of the body. Due to these differences, it seems that the two species are not closely related, however, it's quite possible that they share a yet-undiscovered common ancestor.

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.
