Explanation:
<em><u>The endosymbiotic theory states that some of the organelles in eukaryotic cells were once prokaryotic microbes. Mitochondria and chloroplasts are the same size as prokaryotic cells and divide by binary fission. Mitochondria and chloroplasts have their own DNA which is circular, not linear.</u></em>
I think it is the secondary ovarian follicle that contains the secondary oocyte.The stages of the ovarian cycle that the follicle will go through includes; a primary follicle contains an oocyte and begins producing estrogen. Then the secondary oocyte contains a secondary oocyte and produces estrogen and some progesterone, then the graafian follicle develops and the secondary oocyte is released a process we call ovulation. the corpus luteum produces progesterone and some estrogen and lastly the corpus luteum degenerates.
Answer:
stimulate blood vessels to develop within cartilage
Explanation:
Most connective tissue, cartilage includes have a very inadequate blood supply because it has no blood vessels innervations in it. It relies on diffusion for nutrient supply of the chondrocytes cells. This is why the chondrocytes divide very slowly compared to other cells. This is exactly the same reason why healing of cartilage takes more time to heal. In addition, due to the chondrocytes fixed position in lacunae, they cannot migrate to a scar to begin the healing process. Cartilages attempt to repair themselves usually by fibrocartilage scar tissue that is not ideal for restoration of movement at a joint.
They transport amino acids
