Answer:

A

Explanation:

All cells undergo division. They employ mitotic and meiotic division process. Mitosis is undergone by all cells while meiosis is peculiar to reproductive cells.

Mitosis is a type of cell division that results in two daughter cells which are identical to each other and the original cell that divided. They are identical in the sense that they have the same number of chromosomes and exact copies as the parent cell. Mitosis is used by organisms for growth and multiplication. Hence it is called DUPLICATION division. It is a one division cycle that separates sister chromatids into two identical cells.

Meiosis, on the other hand, is a cell division that results in four daughter cells (gametes) which have their chromosomal number reduced by half. During meiosis, a two step division occurs viz: Meiosis I and Meiosis II.

Meiosis I involves the separation of homologous pair of chromosomes (similar but non-identical chromosomes received from each parent) into two cells. These cells are now haploid (n).

Meiosis II, which is similar to mitosis, involves the separation of sister chromatids (duplicated chromosome). Hence in total, 4 daughter cells with as half as many chromosomes as the parent cell results.

N.B: Meiosis is used by reproductive cells to produce gametes. These gametes must be haploid in order to ensure that after fertilization with another haploid gamete (opposite), a diploid organism results.

The answer is A. Mitosis results in daughter cells through one division cycle while meiosis results in haploid gametes through two division cycles.

3. Which of the following reflect reasons for America's interest in the Panama Canal?
Rom4ik [11]

"To facilitate the faster movement of naval ships from the Atlantic to the Pacific" reflect one of the reasons for America's interest in the Panama Canal.

<u>Answer:</u> Option E

<u>Explanation:</u>

Panama Canal is an artificial or man-made waterway of 82 km located in transcontinental country in Central America and South America named as "Panama". France was the very first nation to start work on the canal in 1881 but after some engineering issues they eliminated themselves from the project.

In 1901 the United States leaded the project which finally resulted into inaugural ceremony of the panama canal on 15th August, 1914.The bypass, one of the largest and most complex engineering projects ever undertaken, significantly reduced the time for ships to pass between the Atlantic and Pacific oceans. Therefore it allowed them to avoid the long, risky Cape Horn path around the southernmost tip of South America via the Drake Passage or Magellan Strait.

What are the characteristics of red light, which is absorbed by chlorophylls?
Lilit [14]
<span><span>There are choices for this question namely:

A. Its photons have the shortest wavelength in the visual spectrum
B. Its photons have the highest energy in the visual spectrum
C. Its photons have the longest wavelength in the visual spectrum
D. It is not considered a part of the visual spectrum

The correct answer is that </span>its photons have the longest wavelength in the visual spectrum<span>. Chlorophyll, being green in color (around 495 to 590 nm wavelength), reflects this wavelength; not absorbed. Mostly, the chlorophyll absorbs longer wavelengths of light such as red (around 680 nm wavelength) and blue to violet (around 400 to 480 nm wavelnegth). </span></span>
