Biology
1 answer:
max2010maxim [7]3 years ago
7 0

Answer:

1. Metaphase 1

2. Independent assortment

3. Crossing over

Explanation:

Meiosis is a kind of cell division that reduces the chromosome number of the parent cell by half. It only occurs during sexual reproduction and ensures genetic variation in sexually reproducing organisms.

Meiosis contributes to genetic variability when the chromosomes line up randomly at the cell plate during METAPHASE 1 of meiosis. This process of random alignment is called INDEPENDENT ASSORTMENT of genes. Generally, meiosis is able to ensure genetic variability due to a process called CROSSING OVER. Crossing over is a process whereby nonsister chromatids of homologous chromosomes exchanges/shuffles genetic contents.

What is the path that a body follows as it travels around another body in space is
Katena32 [7]

Answer:

The movement is called revolution when a body travels around another body in space.

Explanation:

The movement is called revolution when a body travels around another body in space. It is different from rotation which is a phenomenon where a body revolves around its own axis. For example, we can assume the motion of earth as revolution when it travels around the sun and completes one complete revolution in one year, on the other hand when it moves around its own axis the day and night transformation happens.  We can also take the example of moon which revolves around the earth and many other planets which revolve around the sun. So it is very easy to understand the concept of revolution.

Hope it helps!

In what way is DNA like a book?
Alekssandra [29.7K]
<span>A book contains letters, just like the DNA. It's how the letters are arranged-into words in a book- that makes them mean anything. The same is true of DNA bases. It is how they are arranged that makes them significant.</span>

Why is it beneficial for a leech to be able to store blood for months and release it slowly?
Dominik [7]
The reasons are:
- the blood is very low on nutrition
- the leech is not feeding itself regularly

The leech slows it metabolism a lot, so it can survive on very low nutrition. The blood is very low on nutrition, and it is the leech's food source, so the evolution made it preserve energy.

The leach doesn't have the opportunity to feed itself on regular basis, so it takes maximum advantage of any opportunity and consumes as much blood as possible so that it can survive long term when it will not have food at disposal.
