Which statement below best describes the purpose of meiosis in creating gametes?

Answers

The purpose of meiosis is to produce gametes, or sex cells. During meiosis, four daughter cells are produced, each of which are haploid (containing half as many chromosomes as the parent cell).

The purpose of meiosis is to create gametes. Thus, it reduces the number of chromosomes to half.

What is meiosis?

In sexually reproducing organisms, meiosis is a kind of cell division that results in a reduction in the number of chromosomes in gametes (the sex cells, or egg and sperm). Body (or somatic) cells in humans are diploid, meaning they have two sets of chromosomes (one from each parent).

The egg and sperm that combine during fertilization must be haploid or have only one pair of chromosomes, in order to sustain this state. Each diploid cell divides twice during meiosis to produce four haploid daughter cells, which are gametes.

In humans, autosome cells contain 46 chromosomes, while gametes contain 23 chromosomes. Hence, the main purpose of meiosis is to divide the genetic material in half.

Explanation:

The answer is D. because the actual definition for emigration is: "The act of leaving one's own country to settle permanently in another; moving abroad." The definitions between immigration and emigration are very similar but the actual definition for immigration is: "The action of coming to live permanently in a foreign country." so I would stick with D.

All eukaryotic cells contain at least one Golgi complex, typically located in the cytoplasm and near the endoplasmic reticulum.
Which of the following best describes a process that occurs within the Golgi complex?

Answers

Answer: Enzymatic modification of newly synthesized integral membrane proteins

Explanation: got it right for AP Bio.

The correct answer that describes the process that occurs within the Golgi complex is the enzymatic modification of newly synthesized integral membrane proteins.

Once protein is synthesized, they undergo folding and repackaging within the endoplasmic reticulum before they are transported to the Golgi apparatus/complex.

Within the Golgi complex, the protein is modified enzymatically and encased in vesicles. It is then transported to the cell membrane where they are utilized as integral protein.

So, basically, the statement that best describes the process that occurs within the Golgi complex is the enzymatic modification of newly synthesized integral membrane proteins.

The main function of thrombocytes is to stop the bleeding of injured blood vessels. In mammals, thrombocytes are anucleated cell fragments called platelets.

Thrombocytes is responsible for the clotting of blood.

What are thrombocytes?

The microscopic blood cells known as platelets, or thrombocytes, aid in blood coagulation. Your body naturally stops bleeding with platelets.

Plasma, red, white, and platelet-containing blood cells make up whole blood. Platelets, the lightest component of whole blood, are pushed to the walls of your blood vessels because they are the heaviest part of the blood.

This allows plasma and blood cells to flow through the center, allowing platelets to reach injury rapidly to stop bleeding.

Therefore, Thrombocytes is responsible for the clotting of blood.

Easter Sunday is the first Sunday after the first full moon of spring. To compute the date, you can use this algorithm, invented by the mathematician Carl Friedrich Gauss in 1800: 1. Let y be the year (such as 1800 or 2001). 2. Divide y by 19 and call the remainder a. Ignore the quotient. 3. Divide y by 100 to get a quotient b and a remainder c. 4. Divide b by 4 to get a quotient d and a remainder e. 5. Divide 8 * b 13 by 25 to get a quotient g. Ignore the remainder. 6. Divide 19 * a b - d - g 15 by 30 to get a remainder h. Ignore the quotient. 7. Divide c by 4 to get a quotient j and a remainder k. 8. Divide a 11 * h by 319 to get a quotient m. Ignore the remainder. 9. Divide 2 * e 2 * j - k - h m 32 by 7 to get a remainder r. Ignore the quotient. 10. Divide h - m r 90 by 25 to get a quotient n. Ignore the remainder. 11. Divide h - m r n 19 by 32 to get a remainder p. Ignore the quotient. Then Easter falls on day p of month n. For example, if y is 2001: a = 6 h = 18 n = 4b = 20, c = 1 j = 0, k = 1 p = 15d = 5, e = 0 m = 0 g = 6 r = 6Therefore, in 2001, Easter Sunday fell on April 15.
