What would happen to a cell if its mitochondria stopped working? And why would it happen!?

Answers

The cell would die. This is because mitochondria are essential for making energy that the cell can use, if the mitochondria stopped working this energy would not longer be available to the cell. If the cell does not have energy, it cannot perform vital functions like respiration.

What are the two types of behavioral adaptation

Answers

Answer:

The 2 types of behavioral adaptation are migration, and hibernation.

Explanation:

Adaptation of animal is the fitness towards its environment. If an animal can't adapt, it will perish with time. Adaptation may be genetic or acquired. But basically, adaptation is 2 types - physical adaptation, and behavioral adaptation.  

Physical adaptation includes the coloring of the body, camouflage activity of an organism. The behavioral adaptation is the respond of the organisms to their habitat. This includes hibernation, estivation, migration, etc.

Some animals are affected by the temperature difference of the environment. Therefore, they adopt some methods to survive in extreme temperatures.

The cold-blooded like amphibians hibernate during winter.  They undergo a long sleep during cold weather and become active in summer.  Similarly some animals like desert lizard active in the morning. When the temperature increase they burrow themselves under the ground. This is called estivation.

Birds migrate during the adverse season i.e. in winter. They temporarily go to a different place to spend the cold month and return during the advent of summer. This is one type of behavioral adaptation. They also migrate for better breeding ground and food.  

Some fishes also migrate for breeding and food.

All organisms have adaptations that help them survive and thrive. Some adaptations are structural. Structural adaptations are physical features of an organism like the bill on a bird or the fur on a bear. Other adaptations are behavioral. Behavioral adaptations are the things organisms do to survive. For example, bird calls and migration are behavioral adaptations.
Adaptations are the result of evolution. Evolution is a change in a species over long periods of time.
Adaptations usually occur because a gene mutates or changes by accident! Some mutations can help an animal or plant survive better than others in the species without the mutation.
For example, imagine a bird species. One day a bird is born with a beak that is longer than the beak of other birds in the species. The longer beak helps the bird catch more food. Because the bird can catch more food, it is healthier than the other birds, lives longer and breeds more. The bird passes the gene for a longer beak on to its offspring. They also live longer and have more offspring and the gene continues to be inherited generation after generation.
Eventually the longer beak can be found in all of the species. This doesn't happen overnight. It takes thousands of years for a mutation to be found in an entire species.
Over time, animals that are better adapted to their environment survive and breed. Animals that are not well adapted to an environment may not survive.
The characteristics that help a species survive in an environment are passed on to future generations. Those characteristics that don't help the species survive slowly disappear.

The diagram shows the process of meiosis. How many divisions are required to decrease chromosome numbers and produce gametes?

Answers

The answer to that question is B or in other words 2.

Answer:

The answer is 2 divisions

Explanation:

Cells undergoing meiosis require 2 sets of divisions because only half of the cromosomes from each parent are needed. This means that the offspring is going to have mutations/change in order to survive on Earth or even other planets! When this keeps happening us humans keep evolving.
