<span>The cytoskeleton is a
structure found in the cytoplasm that is composed of a web of proteins. It is a
network composed of protein microfilaments, intermediate
filaments, and microtubules. They can be found in all living organisms and are
responsible for giving them their distinct cell shapes and coherence.
Aside from
providing the cell shape, the cytoskeleton is also responsible for cell
movement, organelle movement, and cell division.</span>
<span>It plays a crucial role in
cell division because they provide the movement of chromosomes to the daughter
nucleus. The absence of these protein filaments would result to different
abnormalities and diseases in the genes. </span>
Answer:
c. Individuals experience differential success in their ability to survive or reproduce due to differences in certain traits.
Explanation:
Natural selection works on a population when genetic variations are present in its members. Some genetic traits make the organisms better adapted to the prevailing surroundings. These individuals survive more and reproduce more successfully due to the presence of specific genetic traits. Over the generations, the proportion of the beneficial genetic trait increases due to the increased reproductive success of these individuals. This is called natural selection. On the other hand, the individuals that lack these traits survive and reproduce less.
Answer:
A mineral reserve is a resource, or a portion of a resource that can be mined profitably. It’s quantity and quality have been demonstrated to the point that there is real certainty that it exists that way. Allowances have been made to include dilution (non-ore rock that is mined with the ore), and mining losses ( you can never mine it perfectly).
A resource is an estimated quantity of a mineral of economic interest, that has potential to be mined economically. It can have less certainty than a reserve.
