The woolly mammoth lived a long time ago when the climate of Earth was very cold. They had a thick layer of fat to keep them warm, long tusks for digging in the snow, and hair that covered their bodies. The woolly mammoth ate grasses and plants. As Earth's climate became warmer, humans began to move into areas where the woolly mammoth lived. They became extinct thousands of years ago.

Which does NOT describe a reason that the woolly mammoth became extinct?
A.
Humans removed all of the predators from the area.

B.
Humans began to hunt the woolly mammoth.

C.
The food supply changed with the climate.

D.
The woolly mammoth could not adapt to a warmer climate.

Answer:

D.

Mean: 24.8

Median: 26

Mode: 26

Explanation:

The mean is the average. To find the average, add up all the numbers and divide by the amount of numbers there are.

30 + 26 + 25 + 11 + 34 + 20 + 26 + 26 = 198

Now, we divide by how many numbers we started out with (8).

198 divided by 8 = 24.75, rounded would be 24.8

To find the median, you arrange the numbers from smallest to largest, and find the middle number like this:

11, 20, 25, 26, 26, 26, 30, 34

As you can see, the middle number is 26.

To find the mode, you arrange the number from smallest to largest, and find the number that appears more often.

11, 20, 25, 26, 26, 26, 30, 34

As you can see, the number 26 appears the most often.

So, we end up with:

Mean: 24.8

Median: 26

Mode: 26

Explanation:

Answer/Explanation:

The ability to obtain and use energy is one of the eight characteristics of all living things.  Scientists classify organisms based on how they get their energy: autotrophs or heterotrophs.  Organisms are divided into three main groups- the producers, the consumers and the decomposers.  

Producers get their energy from abiotic factors (non-living sources).  Most producers are plants and get their energy directly from the sun using a process called photosynthesis.  There are also some bacteria that can make their own food from chemicals using a process call chemosynthesis.  Examples of common producers are grasses, trees and flowers.  Algae (which are protists, not plants) are the main producers in aquatic ecosystems. Remember we call these autotrophs because they can make their own food.  

Consumers cannot make their own food.  Instead, they get their energy by eating other organisms.  These are also called heterotrophs.  There are many types of consumers.  Herbivores, such as grasshoppers and prairie dogs, only eat producers.  Carnivores eat animals.  Coyotes, badgers, and falcons are all carnivores.  Organisms that eat both producers and other consumers are known as omnivores.  Most humans are omnivores.  Scavengers are a special type of omnivore.  They eat dead plants and animals.  Vultures and many insects are common scavengers.  

Decomposers are a very special type of heterotroph because they get energy by breaking down dead or dying organisms.  Bacteria and fungi (mushrooms, molds and mildews) are examples of decomposers.  Decomposers are important to ecosystems because they return important nutrients such as water, carbon dioxide and nitrogen to the soil.  Plants then use these nutrients to grow, creating a cycle of nutrients through the ecosystem.        

Each of these organisms depends on the others.  Producers get energy from the sun or chemicals and then give some of this energy to consumers.  The consumers then give some of their energy to the decomposers.  Together, these organisms form a food chain.  A food chain is a series of events in which food energy is transferred from one organism to another.   All food chains have the basic structure of producer  ⇒ primary consumer  ⇒ secondary consumer ⇒ tertiary consumer  ⇒ decomposer.  There are many overlapping food chains in an ecosystem.  These overlapping food chains are known as a food web.  

As energy passes from level to the level in a food chain within a food web, the amount that each organism receives decreases.  For example, in a grassland ecosystem, the grasses get energy needed for life from the sun.  Some of this energy is used by the grass to grow and reproduce.  When a prairie dog eats the grass, it only gets 10% of the energy the grass originally had.  The prairie dog then uses some of the energy from the grass to grow and reproduce.  When a coyote eats the prairie dog, it only gets 10% of the energy the prairie dog originally had.  This decrease in energy at each level of the food chain can be represented by an energy pyramid.

Explanation:

Genetics yo,

The correct answer is option B.

Diffusion is the process of movement of both the solute and solvent. the characteristic of diffusion is that it does not require a membrane or a layer separating two parts. In diffusion particles or solutes move from a region of higher concentration to a region of lower concentration.

In the example, we can see that red particles are together in a place and after some time they get distributed evenly in the entire liquid. This process is known as diffusion as it does not require a membrane.

Answer:

A. Humus occurs in nature unaided by humans

Explanation:

got it correct in my quiz hope this helps and have a nice day :)

The difference between compost and humus is that humus occurs in nature unaided by humans, which is the first option, as humus is a natural organic substance that forms over a long period of time as organic matter, and compost is created by humans.

Humus is a naturally occurring organic material that is formed through the natural decomposition of plant and animal matter over a long period of time. It is a stable form of organic matter that is resistant to further decomposition, and it can persist in soil for centuries or even millennia. Compost is a valuable soil amendment that can be used to improve soil health and fertility. Unlike humus, which is a stable form of organic matter, compost is a more dynamic material that continues to break down over time.

Hence, the difference between compost and humus is that humus occurs in nature unaided by humans, which is the first option.

Answer:

I think its the 3rd answer

Explanation:

The first answer could be close but if the forest was mostly destroyed, then it would not have plenty of food for them. They also might not prefer the food there. The second option isn't correct because the deer wouldn't take their chances being around creatures (humans) that they have never seen before or didn't see that much. Also, the sound of the construction would scare them off. The fourth option isn't correct because while yes, the lights may disorient the deer, it probably wouldn't want to make the deer wander into the neighborhood. When you see a deer looking in headlights, they don't walk towards your car, they just stand there. This is why I think the 3rd answer is correct.

Answer:

Adaptation can protect animals from predators or from harsh weather.

Explanation:

Many birds can hide in the tall grass and weeds and insects can change their color to blend into the surroundings. This makes it difficult for predators to seek them out for food.
