The answer is a because sex traits have more prominent antlers then those
38) I believe the correct answer would be letter D: ions are moved against the concentration gradient.
39) I believe the correct answer is letter A: the DNA information for development was silenced in differentiated cells. This is because the frog did not go through <span>embryonic development.</span>
Answer: Option (d) is the correct answer.
Explanation:
Nucleus of an atom consists of protons and neutrons. Protons are positively charged and neutrons have no charge. So, due to the like charges of protons there occurs electrostatic force of repulsion inside the nucleus of the atom.
But due to similar number of neutrons and protons a force that is able to bind both of them together is known as strong nuclear binding energy.
This force is strong enough that it is able to overcome electrostatic force of repulsion. But when there is great difference in the number of protons and neutrons then binding force is not strong enough.
Hence, the atom becomes unstable and undergoes radioactive decay. So, this means weak forces are responsible for radioactive decay.
Thus, we can conclude that the statement which best describes Yanni’s error is that the strong force is responsible for radioactive decay.
Answer:
This is an example of adaptation due to a progressive mutation
Explanation:
At the beginning, the bacteria can use the galactose as carbon source for it needs, but since this food is getting out in every new generation. The new generations can be adapted to survive with smaller quantities of galactose until there will be one generation that can survive with any galactose source, when this offspring reach the area of the plate without galactose, then it can be grown in ant area.
