39%. Adenine would have the same percentage as Thymine, meaning it would he 32% A and T and then subtract that from 100 giving you 72 divide that by 2 and you get part Guanine and part Cytosine.
It is c. Find phenotypic ratio
Answer:
a. commensalism is the correct answer.
Explanation:
By growing on the trunk or branch of a tree, a lichen gains height and exposure to sunlight for photosynthesis. The tree is not harmed by the lichen but does not benefit either. The relationship between the lichen and the tree is commensalism.
Commensalism is a relationship between two organisms where one organism gets benefits from other organisms without causing any harm or any damage from the relation as it one side symbiotic relation.
In this, we can see lichen is getting benefits from the tree.
for example, lichen is getting following benefits from the tree such as ( a lichen gains height and exposure to sunlight for photosynthesis.) and they are causing any harm to tree neither any benefits so this is a one-side symbiotic relation and thus the relationship is an example of commensalism.
Answer:
Option B, Snakes and lizards share a common ancestor.
Explanation:
From the description provided, it is clear that both the lizard and snake (including pythons) have evolved from the same ancestors which had hind legs. Since both the organism (i.e lizard and snake) underwent evolution (differently) for million of years such that the hind legs in lizard are visible and used even today but the hind legs in snakes are buried in muscles toward their tail ends and are not used. Such features which are not used at all or are poorly used are called as vestigial organs.
Hence, option B is correct
