The answer should be
B Both anabolic and catabolic reactions took place in the seed and tree when it was young and growing and both continue now even though the tree reached a stable mass.
The trees should be capable to do both anabolic and catabolic reaction when it is seed or when it is already a big tree. Anabolic reaction happens when the plant making bigger molecule from many smaller molecule, such as in photosynthesis. Anabolic reaction could increase the mass of the plants or be used to make food. Catabolism reaction used to extract energy from the food.
<span>Well, since there is little genetic variation, all the animals in the population are fairly similar, from a purely physical standpoint. Therefore, if there was some new form of whale lice that kills northern right whales, then presumably at least nearly 1/3 of the population would be vulnerable to this new form of whale lice. This is over simplified, but in essence a huge portion of the population is much more vulnerable to a single threat due to common disease resistances, or the lack thereof.</span>

I don't understand what you are asking for
Answer:
Smaller the size of the DNA fragment, farther it moves during electrophoresis. The sketch of the position of the fragments has been drawn in the figure below.
Explanation:
As we know DNA is a negatively charged molecule. So during electrophoresis the fragments move towards the positive electrode because opposite charges attract each other.
Different fragment move different distances according to their size during the electrophoresis. Smallest segment travels the largest distance in the gel medium while the largest one travels least distance.
In the question there are four DNA fragments with base pairs 4000, 2500, 2000 and 400 so the smallest segment with 400bp will be farthest from the starting point and the largest fragment with 4000bp will travel least distance in the gel medium. Their respective positions are shown in the figure below. The starting point is near the negative electrode.
Taxonomy scientists classify living things on eight different levels, In order to do this, they look at characteristics, such as their appearance, reproduction, and movement, to name a few.
