Answer:
endosymbiosis.
Explanation:
By the beginning of the 20th century, researchers thought that plastids and mitochondria could come from bacteria. These would have been ingested by primitive cells and live within them in symbiosis.
Answer:
In humans, the major precursors from which glucose can be synthesized from are:
1. glycerol from triacylglycerols
2. glucogenic amino acids from protein.
3. Oxaloacetate formed from CO2
4. Pyruvate foem pyruvate carboxykinase
All there's are routes through which the body obtains glucose to replenish body glucose levels

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.
