<span>The correct answer is 10 chromosome. Mitosis is the type of cell division that takes place in the somatic cells or the body cells where the parent cells divides into two daughter cells with the same genetic composition as the parent. Therefore, the number of chromosomes in the daughter cells remains the same as that of the mother cells. The opposite is the meiosis, which involves division of a germ line cells into four daughter cells which contains half the number of chromosomes as the parent. </span>
The correct answer is that a population overshoots the carrying capacity and environmental pressures and shortfalls begin to exert their effects. A certain area of environment only has limited resources such as food, water, habitat, etc. These limited resources are called the carrying capacity of the environment. If the population exceeds the carrying capacity of the environment, there will be not enough resources to sustain the population therefore members of the population will die and the overall population number will crash hence the term <em>population crash. </em>

Answer:
The dog leash has become the conditioned stimulus
Explanation:
In classical/respondent conditioning, antecedent events become associated with one another.
A stimulus that does not typically produce a response is paired with one that does.
Learning is said to have taken place when the stimulus that did not produce a response begins to elicit a response.
In this scenario, the stimulus that does not elicit a response (neutral stimulus) is the dog's leash and after a while, it becomes the conditioned stimulus.
Rattling the chain is the stimulus that has been paired with walking the dog.
