Answer:

A

Explanation:

<em>The active state of cell division covers the prophase, metaphase, anaphase, and telophase. The total number of observed cells that were undergoing cell division can, thus, be calculated by adding the number of cells in each stage of the cell division.</em>

Total number of cell in division = 20+4+2+4

                = 30

Probability that a randomly chose cell will be undergoing cell division = <em>number of cells in division/total number of cells</em>

     = 30/200

          = 0.15 or 15%

The correct option is, therefore, A.

Natural selection refers to all of the following EXCEPT
elena-14-01-66 [18.8K]

Answer:

Darwin proposed the theory of natural selection to explain the process of evolution. According to Darwin’s theory of natural selection, all organisms have the potential to reproduce limitlessly irrespective of the fact that each species maintain a constant density over time. However, the struggle for existence, i.e. the competition among individuals for available resources to survive and reproduce, put a check on species density (D) and maintains it at a constant level (B). Survival of fittest is unequal ability of individuals to survive and reproduce based on suitability of their inherited characters to prevailing environmental conditions (A). It imparts the reproductive advantage to certain organisms which account for major part of the gene pool of the species. Thus, natural selection favors the individual with survival and/or reproductive advantage over others under existing environmental condition (E). Thus, the correct answer is option C.

What does the mitochondria need to make energy for the cell?
Pachacha [2.7K]

Is the space between the bottom of the objective lens and the surface of the slide.
Svetlanka [38]

WORKING DISTANCE is space between the bottom of objective the lens and the surface of the slide.

The distance between front edge of the objective and the lens and the specimen surface ("with the surface of the cover glass in case of the cover glass objective lens") when the specimen is also focused.

The working distance (W.D.) which is determined by the linear measurement of the objective and front lens to the focal plane. In the general, the objective of the  working distance decreases by the magnification and the numerical aperture of both increase. The working distance is the distance and from the front of the lens to be the focal plane
