Human red blood cells contain an important protein called?

Biology
1 answer:
Vika [28.1K]3 years ago
7 0

Answer:

Explanation:

Red cells contain a special protein called hemoglobin, which helps carry oxygen from the lungs to the rest of the body and then returns carbon dioxide from the body to the lungs so it can be exhaled. Blood appears red because of the large number of red blood cells, which get their color from the hemoglobin.

Lostsunrise [7]
<span>Meiosis in simple terms is the process by which gametes (sperm and egg) fuse together to produce a fertilised egg. Haploid is a word that refers to how many chromosomes a certain cell has. In this case the gametes have a haploid number of chromosomes, which is half the number a normal cell has. A normal cell has a diploid number of chromosomes. So in meiosis the two gametes come together with their hapoid number of chromosomes each to create an egg that has a diploid (standard) number of chromosomes.</span>

During sexual reproduction, two gametes merge to create a zygote that is a genetic mix of its two parents. For each statement, i
Elenna [48]

Answer:

1. 50% of the genome comes from each parent because it is crucial otherwise if the ratio changes, the zygote may not form and if formed the fetus may have some other kind of chromosome number related syndromes etc.

2.  Sexual reproduction produces greater genetic variability than asexual methods. This is because of the process of crossing over during meiosis that exchange the segments of chromosome that is necessary for producing mutations and genetic variability.

3. 50% of chromosomes match with each parent because both of the parents contributed 23 chromosomes and exactly 50% of their genome.

4. The gametes must be produced by two different individuals cause that is the main purpose of sexual reproduction and give better survival like this to the forming next generation. Not to mention produces greater genetic variability among species.

5. Plants always produces both eggs because they are hermaphroditic in nature.
