The correct answer in this question is option B. The electronegativity increases across a group. Chlorine ion has a higher electronegativity than the sodium ion. Chlorine need one electron to have a noble gas configuration that is why it gets one electron every chance it makes.

Phoenix [80]

Answer:

cellular respiration

Explanation:

All exergonic processes produced in the cell, through which substances oxidize and chemical energy is released, are grouped under the name of cellular respiration, but to break down an organic molecule the cells employ, mainly dehydrogenations that can be carried carried out in the presence or absence of atmospheric O2 oxygen. There are therefore two types of breathing: aerobic respiration and anaerobic respiration. The latter also called fermentation.

Aerobic respiration  (oxidative phosphorylation)

- Use molecular O2.

- It degrades glucose to CO2 and H2O

- Exergonic

- Recovers about 50% of chemical energy

- Present in most organisms.

- It uses enzymes located in the mitochondria.

Answer:see attached photo for answer

Explanation:cell division occurs to produce new cells from preexisting ones. the new cells are called daughter cells.the old cells are called parent cells.cell division may be mitosis or meiosis. Mitosis occurs in a somatic cell and produce four daughter cell. Meiosis occurs in sex cells and produce two daughter cells. Cell division usually involves Prophase, metaphase, anaphase and telophase.

Cell division occurs to ensure the continous existence of life.

Mitosis involve producing daughter cells with the same number of chromosomes as the parent cells while meiosis involves producing daughter cells with Half number of chromosomes.
