Answer:
The correct answer is allopatric speciation.
Explanation:
Allopatric speciation occurs when a geographical barrier comes between a species population living in the same area. This geographical barrier separates the population into two different geographical area which do not have the same condition.
So as both the separated population get different habitat environment to live so they evolve differently from each other. So natural selection and genetic drift works differently in both the population which brings genetic changes in the population and helps in creating a new species.
Consider the two statements and use the following key to choose your answer. (1) the number of sympathetic neurons that innervate sweat glands (2) the number of parasympathetic neurons that innervate sweat glands Select on. (A) First item is greater than the second item.
:Answer: Option (A) is correct
Explanation:
The sweat glands are innervated only by sympathetic neurons system ,they help in maintaining the body temperature.Innervate means to supply energy to something.Sympathetic neurons prepare the body to fight in case of any danger but on the other hand parasympathetic neurons prevent the body from over working and make it calm.sympathetic neuron system response fast as compared to parasympathetic neurons.
The number of sympathetic neurons that innervate sweat glands is greater than parasympathetic neurons that innervate sweat glands.
He or she is said to be in a positive
nitrogen balance state.
Nitrogen balance is the
traditional method of determining dietary protein requirements. Determining
dietary protein requirements using nitrogen balance requires that all nitrogen
inputs and losses are carefully collected, to ensure that all nitrogen exchange
is accounted for. Positive nitrogen balance is associated with periods of
growth, hypothyroidism, tissue repair, and pregnancy. This means that the
intake of nitrogen into the body is greater than the loss of nitrogen from the
body, so there is an increase in the total body pool of protein.
