Answer:
20%
Explanation:
cytosine = guanine = 30%
cytosine + guanine = 60 %
adenine + thymine =100% - 60% = 40 %
thymine = 20%
Answer:
500
Explanation:
Mutation rate is largely known as changes that occur in the frequency of a particular gene over an extended period of time
So given that;
the mutation rate of a particular gene = 1 × 10⁻⁶
The expected mutations after 500 million sperm are examined will be:
= (1 × 10⁻⁶)×(500,000,000)
= 500
Thus, The expected mutations = 500
Decomposers include earthworms, small soil beetles, fungi, and bacteria. A food web shows how food chains overlap. The same three types of organisms are in food webs: producers, consumers and decomposers. Good food webs should also include the sun as the initial source of energy.
The preferred prey item would be frogs.
What is optimal foraging theory?
It is a theory in ecology that proposes that predating animals that get the most energy from minimal efforts are favored by natural selection.
In order words, selection forces prefer investing minimum energy in order to extract maximally available energy.
In this case, the heron needs to use the lowest time to harvest the maximum energy possible. Since all the preys offer the same amount of energy, the one that requires the lowest time would be preferable for the heron.
In other words, frogs would be the most preferable prey.
