Answer:
0.1
Explanation:
The Net Reproduction per individual per unit time (r) can be calculated as (births-deaths)/population size
Given that:
Population size of mice = 1,000; Birth = 500; Death = 400,
Net reproduction rate (r) = (births-deaths)/population size
r = (500 – 400)/1000
r = 100/1000
r = 0.1
The Net reproduction per individual per unit time (r) is 0.1
Answer:
tentatively group it with birds and speculate that the trait shared only with bats is a derived rather than an ancestral trait with bats.
Explanation:
The scientist after his observation should tentatively classify this organism with birds and the the second end of calculating the other morphological traits which makes it possess the likely bat traits to be ancestral.
According to scientists, most widely used modern systematic practice
depends upon the assumption that a change from character in one species
to character occurs once and once only in the evolutionary process and that this process is irreversible so that it never returns.
In this scheme, there are no independently derived parallel evolutionary changes,
nor convergences from a variety of states to a single one. Therefore, when two organisms share a
character state different from other species, it is because they are more closely related to each other through a recent common ancestor than they are to other species.
Also using the parsimony principle, a scheme of common ancestry for all the species is derived that uses all the characters that have been observed.
The plasma membrane of axon is called axolemma. The potassium and sodium leak channels leak the sodium and potassium ions inside the cell respectively. The leak channels provide the constant movement of ions across the membrane. Potassium and sodium ions are positively charged, thus entry of positively charged ions inside the cell makes the cell more positively charged than the environment outside the cell. The environment outside the cell becomes more negatively charged. This leads in the negative membrane potential of axolemma.
