The two homologs of a pair move toward opposite poles of dividing cell during

Biology
1 answer:
kvasek [131]3 years ago
4 0

Answer: B, Meiosis I

Explanation:

During meiosis I, genetic material halves, and you get 2 haploid cells (n) from a diploid cell (2n). Those divide again during meiosis II to form 4 different haploid cells.

DNA replicates during interphase and starting at meiosis I, 2n homolog chromosomes attach to form n tetrads. Those tetrads align in the cellular equator during metaphase I and then separate, moving to opposite poles during anaphase I. Each cell formed receives a copy of each chromosome and then divides in a process similar to mitosis during meiosis II.

Acid rain can cause many problems, such as stripping paint and burning skin, but I believe the answer you are looking for is "decay," which is the process that occurs when an organism decomposes.

What kind of cell results when a diploid and a haploid gamete fuse during fertilization?
Elena L [17]

Answer:

The correct answer is: a triploid cell.

Explanation:

A triploid cell is the result of the fertilization of a diploid cell and a haploid cell. Triploid cells have 3 sets of chromosomes, diploids have 2 sets, and haploids have only 1 set.

Humans, besides many other species, have diploid cells - one set of chromosomes comes from the mother and the other set of chromosomes comes from the father. <u>In order to maintain this number, </u><u>gametes</u><u> (the sex cells: spermatozoids and oocytes) become haploid through meiosis</u>. This way, when the spermatozoid fertilizes the oocyte, the resulting cell will be diploid.

A gamete being diploid is a result of an <u>error during meiosis</u>, and will most likely generate a triploid cell during fertilization.

A triploid cell, unfortunately, <u>won't be able to survive,</u> so they are almost always spontaneously aborted in the first two weeks of pregnancy.

Similarities between seemingly unrelated organisms can be explained by Darwin’s theory that organisms come from common ancestors
Svetlanka [38]
<span>Darwin's theory with relation to similarities amongst unrelated organisms looks at either similar form or similar function of appendages and from this it is postulated that some organisms have common ancestors based on these similarities. A broad example would be the fact that most vertebrates (organisms with spines) stemmed from one or a group of common ancestors, while invertebrates (lack of a spine) are related to common ancestor or groups of common ancestors. So the answer to the question is yes, it is true.</span>
