<h3><u>Answer;</u></h3>
D. Sodium Ions
<h3><u>Explanation;</u></h3>
- Ions play important and variety of roles in cellular activities.
- The composition of the cell interior is markedly different from the outside environment of the cell.
- The dominant positive ion within the cell is potassium with a concentration that is more than 10-fold higher than that of sodium.
- Outside the cell the major positive ion reverses with sodium as the dominant positive ion.
The correct answer is option D, that is, it will increase the amount of carbon in the soil and increase the amount of carbon dioxide discharged by decomposers.
One of the ways to manage the garden is to utilize mulch, the mulch minimizes the contact between the soil and the organic matter so that the species will consume more time to dissociate it. The mulch will decompose and its nutrients will be discharged to the soil, however, it takes place very gradually, and enhances the organic matter in the soil.
If the mulch is left in the garden for a year, then the soil will be conserved and supplied with nutrients and this process will retain carbon in that garden. The sources of mulch can be leaves, grass, straw, or composted garden waste.

Answer:
In vitro fertilization (IVF)
Explanation:
In vitro fertilization is conducted when infertility is perceived in sexual partners trying to have a baby. It is the process whereby matured ova/eggs are removed from the female's reproductive system and is fertilized externally in a laboratory (usually in a glassware) using a male's sperm cell. It can be thought of as a procedure where the normal fertilization process that occurs in a female's reproductive tract (fallopian tube) is carried out outside the body, specifically in a laboratory.
In order for this procedure to be employed, the male and female must be able to produce their respective gametes. The female's ovary is usually stimulated by fertility drugs in order to yield numerous eggs, which are then extracted from her ovary and fertilized by a sperm externally (in a laboratory). The resulting fertilized egg called embryo is placed back into the female's womb to carry it as a normal pregnancy.
