Artificial selection occurs when organisms are chosen to breed because they possess specific traits. for example, artificial selection has resulted in a wide variety of domesticated cat breeds, such as the maine coon and the siamese. in the artificial selection of cats, the parents of the offspring are chosen by

In the artificial selection of cats, the parents of the offspring are chosen by particular phenotypic traits (characteristics), choosing two adults that possess a desired trait which typically will sexually reproduce and have offspring together. They are bred together to produce desirable traits.

Explanation:

Selective breeding, also known as artificial selection, is a process used by humans to develop new organisms with desirable characteristics. It can be used to produce tastier fruits and vegetables, crops with greater resistance to pests, and larger animals that can be used for meat.

These are the main steps involved to selectively breed:

1.  Decide which characteristics are important enough to select.

2. Choose parents that show these characteristics.

3. choose the best offspring from parents to produce the next generation.

4. Repeat the process continuously.

There are important benefits of selective breeding, like its capability to eliminate animal and plant diseases. Studies revealed that identifying and pre-screening particular diseases allows farmers to control them. Thus, sooner or later, genetic diseases in plants and animals in the future will be eliminated. Another benefits that could be mentioned are to get more nutritious and tastier food; to grow drought-resistant plants that require fewer environmental resources (such as water and fertilizer)  and less use of pesticides;  increased supply of food with reduced cost and longer shelf life and faster growing plants and animals.

option a is correct i.e.

explanation:

in context to the membrane of nerve impulse, the outer membrane of neuron is semi permeable that is only sodium ions can pass through the membrane i.e. smaller ions can pass through the membrane while larger ions cannot pass through it.

i believe your answer would be c.. : )
