Answer:
For functioning of heart, circulatory and execratory systems are required.
Explanation:
It requires at least two body systems to perform the function because the functions does not be completed solely, it requires coordination among systems which help them to fulfill their task. For example, the function of the heart requires circulatory system and execratory system for the pumping of blood throughout the body. it is an involuntary action which is not control by nervous system.
Answer:
TTppRR will produce TpR gametes. ttPPrr will produce tPr gametes.
Explanation:
Let us assume:
Normal tail : T, Tail less : t, Pale skin : P, Dark skin : p, Smooth skin : R, Rough skin : r
A pure-bred normal tail, dark skin, smooth skin mouse and a pure-bred mouse that is tail-less, pale skin, and rough skin crossed together then,
TTppRR x ttPPrr
One allele from every gene comes in a gamete thus, TTppRR will produce TpR gametes. ttPPrr will produce tPr gametes.
Answer:
True
Explanation:
A change in DNA can affect amino acid folding order
<u>Answer:</u>
The correct answer for this is: Microevolution.
<u>Explanation:</u>
The change of England's Biston betularia moth populations from light colored to dark colored is an example of 'Microevolution'.
Basically, the change that occurs over time in the allele frequencies within a group of species or population is known as microevolution.
The four processes due to which this change occurs include gene flow, selection (natural and artificial), mutation and genetic drift.
We can confirm that a person with very toned muscles likely has tightly packed myofibrils.
<h3>What are myofibrils?</h3>
These fibers are the protein filaments that cause contractions in the structure of the muscle. Weight training tones muscles by increasing the number of myofibrils in a sarcomere, thus increasing its capacity to produce force.
Therefore, we can confirm that a person with very toned muscles likely has tightly packed myofibrils.
