Develop a hypothesis to explain why you think eurypterids developed legs even though they lived on the ocean floor.

expeople1 [14]

I think that since it lives on the ocean floor, at the deepest of the ocean. So anyway, the fin on the Eurypterids is still necessary but not that much, since they live on the ocean floor. Their movements mostly on the ocean floor. So fin would not help them "stick" to the floor. Also there are still gravity acts on the Eurypterids and the feet would help them move faster. Hope this helps.

Answer:

Answer is A. B-hemoglobin mRNA is translated more efficiently than is a-hemoglobin mRNA.

Explanation:

The introduction of electric charge into a gel or fluid, causing or resulting in the movement of the charged particles in the gel or fluid, is referred to as the electrophoresis. It can also be explained as a separation method or technique which is based on the movement of particles or ions in an electric field.

The electrophoresis is used in separating DNA fragments , RNA or protein, based on their size and charge.

Please answer 5&6. Thank you.

erastovalidia [21]

Answer:

5. The correct answer would be an option A. ova

Note: I assume that all the samples are of human origin.

DNA (deoxyribonucleic acid) content of somatic cells of humans consists of 46 chromosomes or 23 pairs of chromosomes. Gametes (sperm or ova) are haploid cells produced by the process of meiosis and contain half the number of chromosomes found in parent cell. Hence, they contain 23 chromosomes.

6. The correct answer would be an option J.

Sperm formation or spermatogenesis is the process by which spermatozoa (haploid gamete) is produced from germ cell with the help of meiotic division.

Meiosis results in the formation of four haploid (n) cells from single diploid (2n) parent cell. Here, 2n is given as 8 so, n would be equal to 4.

Meiosis I results in the formation of two secondary spermatocyte cells (both haploid or 4 chromosomes in this case) from single primary spermatocyte (diploid or 8 chromosome in this case).

Both the secondary spermatocytes undergo meiosis II to produce 4 spermatids (each haploid or 4 chromosome in this case). Spermatids differentiate and mature into spermatozoa.
