a bee pollinates flowers to help it grow
Answer:
The mitotic spindle attaches to the kinetochores at the centromeres of the chromosomes and then it moves toward the poles of the cell. Thus, sister chromatids are separated simultaneously at their centromeres so that each daughter cell will have the same genetic material as the parent cell (i.e., daughter cells will be genetically identical to the parent cell).
Explanation:
The mitotic spindle is a structure composed of microtubule proteins whose function is to ensure the correct segregation of the chromosomes during mitosis. During metaphase, microtubules from the mitotic spindle bind to the kinetochore (a protein complex assembled on the centromeric region) in order to align sister chromatids on the metaphase plate. Subsequently, during anaphase, the mitotic spindle moves toward the poles of the cell, thereby sister chromatids are separated from each other. In consequence, each daughter cell will have the same amount of genetic material (i.e., the same number of chromosomes) as the parent cell.
Both the elephant trunk and human hands are used to grasp objects.
The Elephant's trunk is the part of the elephant that extends outwards from its face and enables the elephant to pick up things. It is quite similar to the human hands in the sense that it can be used to grasp objects.
However, human hands are made of fingers but the trunk of an elephant is just a long structure that has no fingers. Hence, it is different from the human hands.

A population is a group of individuals of the same species that has the potential to interbreed.
- A population is described as a collection of people who belong to the same species and cohabit a particular area.
- A population is a subgroup of individuals belonging to a single species that coexists sexually and occupies a specific geographic area.
- For certain species, it is simple to determine the geographic limits of a population; for other species, it might be more challenging.
- For instance, the geographic range of plants or animals living on islands is determined by the island's border.
- On the other hand, other species are spread over very large areas, making it more challenging to define the borders of small populations.
