Which element has seven energy levels the only one valence electron

Biology
1 answer:
denpristay [2]3 years ago
5 0

Answer:

Your answer is chlorine.

Explanation:

Valence electrons help in predicting chemical reactions. For example, since hydrogen (H) is in group 1, it has 1 electron in its outer energy level. Chlorine (Cl), which is in group 17, has 7 electrons in its outer energy level and is one electron short of having a "full" outermost energy level.

I hope that helped. :)

I have snap chat if you need it.

Let me know if you need any more help.

Somatic cells of roundworms have four individual chromosomes per cell. How many chromosomes would you expect to find in an ovum
andrezito [222]

Answer:

2 chromosomes

Explanation:

The cell of an eukaryotic organism like roundworm contains the Nucleus, which harbors the genetic material embedded in the chromosome. The number of chromosomes of that organism is contained in each cell.

Somatic cells, also called body cells, are all other cells asides sperm and eggs, that form the tissues and organs of an organism. Somatic cells are usually diploid i.e two sets of chromosomes from each parent. In this question, the roundworm has 4 chromosomes in its somatic cell.

The reproductive cells or sex cells (sperm and eggs) of an organism always result from meiotic division of specialized cells.

Since meiosis is a kind of division that results in cells with their chromosome number reduced by half (haploid), it therefore means that the ovum and sperm cell will be expected to contain 2 chromosomes each.

This way, when fertilization occurs (sperm and egg fusion), the resulting zygote, which will eventually develop into an adult organism, will have 4 chromosomes.
