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.
Answer:
option A
Explanation:
ornithine is a non-protein and non-essential amino acid it is formed in plant by L-glutamate and in animals it is formed during the urea cycle by the catalyzation of arginine which is an enzyme. In vivo ornithine is not found in protein synthesis because it do not have any codon so it can not endoded by DNA but can be synthesized.
Ornithine is a precursor of glutamic acid, proline amino acid and citrulline amino acid
the air's oxygen is partially replaced by carbon dioxide. This is because of the gas exchange that occurs so we can live.
When cells reach their size limitations one of two things will happen: they will either stop growing and split into two separate cells. Cell division can be both good and bad.
A waste product is a product that is made but isn’t necessarily needed eg. A lightbulb will make light energy but it also makes a waste product heat.
