Bones attach to each other by ligaments.

Bones attach to muscle by tendons.

When muscles contract, bones are pulled to produce movement

Bones attach to each other by joints. Joints allow them to move and pivot around each other in different ways and directions. Bones attach to muscles by a firm, white thing called the tendon. If you cut your tendon in your foot, it would be very difficult to move your foot. The tendon allows movement in the body because muscles are what make bones move, and muscles move bones by pulling on the tendon. Bones move around different bones because the joint is there.

A plant cell can be distinguished from an animal cell because of the presence of?

OlgaM077 [116]

Hi there!

$\large\boxed{\text{A cell wall and chloroplasts.}}$

Plant cells contain a cell wall which causes them to be more rigid in structure, whereas animal cells only contain a cell membrane.

In addition, plants contain chloroplasts, an organelle that allows the cells to undergo photosynthesis to produce energy. Animal cells, on the other hand, only contain mitochondria for cellular respiration.

Dogs are often purposely bred to assure certain desirable traits. What is this type of selective breeding?

siniylev [52]

Artificial selection is the type of selective breeding.

Selective breeding is process of breeding parents with distinct characteristics to produce offspring with more desirable characteristics.

Most of the time the breed of dogs were formerly selected for particular purposes, such as hunting or guarding which needs strong physical endurance. Hence, Selective breeding is evolved by human selection. For example racehorses, having particular traits are desirable in different breeds of dogs that compete in dog shows. Artificial selection, is selective breeding that is imposed by an selective process, in order to get the phenotype of desirable features.

Which of the following is not a natural cause of extinction?

dedylja [7]

Answer:

Introduction of Non-native species would be the answer. ( B )

Explanation:

Now let's break it down.

A. Competition due to overpopulation

Competition due to overpopulation, as competition of resources rises, species will fight among each other, and slowly, population will go down. But I don't see the reason of why it would cause an extinction... perhaps a decrease of population. See, once populations starts decreasing, resources will increase. And ONCE resources increase, populations starts increasing, and there goes competition. Resources decreases, populations decreases, and the whole process repeats. So I'm not quite sure whether it will cause extinction of a species.

B. Introduction of Non- native species.

So what does it mean by Non-native species?

It means that species that have no effect and doesn't exist in the ecosystem. So that will definitely not affect the population whatsoever.

C. Catastrophic Events

Well, common sense. Many people died of tsunamis, tornado and other natural disasters every year. Too many disasters can cause the population to cease.

D. Disease

This we can relate, especially the Coronavirus. Many humans died of the deadly virus. Same goes to animals. If a disease gets too deadly, population will decrease and drive the species to extinction.

So, the Answer would be B.
