Most coastal areas on Earth experience two high tides and two low tides every lunar day. What is a lunar day? Our days on Earth
ahrayia [7]

The correct answer is - C) 5:35 PM Friday.

The low tides occur twice in a lunar day, thus they are diurnal. The low tides appear when the Moon is between that point of the planet and the opposite of that point of the planet, thus in between, which is happening twice, on opposite parts of the planet.

Since the lunar day lasts for 24 h 50 m, we should just divide it in two, thus get 12 h 25 m. Than we should add the 12 h 25 to the time when one of the low tides appeared, which is 5:10 AM, so we will get 5:35 PM.

The low tides appear because the Moon is pulling the water upwards with its gravitational pull above the place where it is, so the side parts of the planet have their waters dragged away,thus resulting in the retreating of the water, known as low tide.

Meiosis reduces chromosome number and rearranges genetic information. Explain how the reduction and rearrangement are accomplish
Alisiya [41]

Answer:

Explanation:

Meiosis is a form of cell division that occurs in the sex cells of organisms. It ensures the reduction of a diploid cell to an haploid cell to allow for the formation of a diploid zygote after fertilization (contribution of both parents haploid sex cells to give a diploid zygote). Thus, this process is very essential and important.

The reduction is accomplished by 2 divisions after the duplication of chromosomes

- first division: separation of homologous pairs of chromosomes (this reduces the total in half)

- second division: separation of sister chromatids of a chromosome.

The rearrangement in meiosis occurs by crossing over/genetic recombination.

This is the exchange of genetic material between homologous pairs of chromosome bringing about a rearrangement and genetic variation

An example of a chromosomal abnormality that arises as a result of defects in this process is the Down Syndrome which is caused by a nondisjunction of the chromosomes 21 pair in a sex cell.

This condition produces offsprings that have some characteristic facial features, short stature etc
