Answer:
D. The threat of predators to eat eggs
Explanation:
The internal gestation followed by live birth was an adaptation developed by the mammals on land, and by some fish in the water, like the sharks. The mammals have been the most marking ones in this adaptation though. They too were producing eggs initially, but because they were living in an environment where there were numerous animals that preyed upon them, as well as their eggs, they had to be innovative. They developed internal gestation, where the embryo was developing inside the body of the female, and then it was born alive. This was providing extra safety, as the embryo was always with the mother, instead of being left alone and not guarded, thus an easy meal for the predators. The two types of internal gestation that the mammals developed are the placental and marsupial types, with the placental turning out to be more successful over time.
A: botulism and typhiod fever

Ovulation is the process of releasing of the mature egg (Greek ovum) from the ovaries. In humans, the mature graffian follicles rupture and the secondary oocyte is released. The secondary oocyte is now ready to be fertilized by the sperm.
Answer:
that break down large molecules into smaller molecules
Explanation:
The lysosome is made up of digestive enzymes. They carry out different cell processes. It can break down work out cells, and can aid in the digestion and the break down of large molecules such as carbohydrates, proteins and also lipids. Lysosome is also helpful in the repairing of cell membranes. They are mostly found in the cells of animals.
