After the zygote begins to divide, a fluid-filled ball of cells, called blastocyst attaches to the uterine wall.
<span>It is the stage of implantation during the prenatal development. The blastocyst consists of an inner cell mass and the outer layer -the trophoblast. Trophoblast surrounds the inner cell mass and a fluid-filled cavity - blastocoele. Inner cell mass will form embryo and trophoblast gives rise to the placenta.</span>
I’m pretty sure it’s diffusion, they’re absorbed into the small intestine and pass through the wall into our bloodstream,
Dark reaction requires ATP, NADPH, and carbon dioxide to produce glucose.
Some conditions that are possible reasons for declining genetic diversity of a species;
▪︎loss of habitat
▪︎inbreeding
Explanation:
Loss of habitat will definitely reduce diversity because it reduces the population size from increased competition for reduced resources. Some subspecies may be completely eliminated when their niche is completely lost.
Inbreeding also reduces diversity because it results in the expression of recessive genes in a population that are mostly disadvantageous. High inbreeding rates will result in most individuals not reaching maturity to pass down their genes to the next generations.
