Answer:
Aerobic activity
Explanation:
Aerobic activity can be defined as a type of physical activity which involves the the circulation of oxgen through the blood.
Aerobic activity is an activity which increases the amount of blood that goes to the muscles. Oxygen is needed for the proper functioning of the muscles.
When carrying out any type of physical activity such as weight lifting the muscles need a large amount of oxygen to function well. The oxygen in the body is used to break down glucose and create the fuel which is needed by the muscles in the form of ATP. Different aerobic activities carried out also helps to strenthen the lungs.
Heat water using the sun during the day, and use it during the cold night.
Use a solar panel to charge batteries during the day, and use the power at night.
Homologous chromosome pairs are separated
Meiosis 1 refers to the initial stage of meiosis where one parent cell divides into two daughter cells. This stage is where homologous pairs of chromosomes will segregate and separate from each other and move into the two daughter cells which result in the division of the total chromosomal number by half.
<h3>What happens during Meiosis 1 ?</h3>
Meiosis I ends when the chromosomes of each homologous pair arrive at opposing poles of the cell.
- The microtubules disintegrate, and a new nuclear membrane forms around each haploid set of chromosomes.
- The chromosomes uncoil, forming chromatin again, and cytokinesis occurs, forming two non-identical daughter cells.
