<span>The product of fertilization is a one-cell embryo with a diploid complement of chromosomes. Over the next few days, the mammalian embryo undergoes a series of cell divisions, ultimately leading to formation of a hollow sphere of cells known as a blastocyst. At some point between fertilization and blastocyst formation, the embryo moves out of the oviduct, into the lumen of the uterus.The images below demonstrate major transitions in structure during early embryogenesis in cattle. Note that in all of the the early stages, the embryo is encased in its zona pellucida. Embryos from other mammals have a very similar appearance, and the general sequence of stages is seen in all mammals.

Bio=Life. So your answer is B-Biosphere.
Heterotrophs
Explanation:
Heterotrophs are organisms that do not perform photosynthesis. They do not obtain their nourishment using products of synthesis of food using carbon dioxide in the presence of sunlight.
- Heterotrophs are consumers in the ecosystem.
- They use food materials from plants for their nourishment.
- The chemical energy stored in food is released during the process of cellular respiration in them.

Answer:
Null hypothesis: the behavior of mosquito larvae doesn't change in the presence/absence of predators added to the tanks in Treatments 2 and 3.
Explanation:
In statistics, the null hypothesis states that there are no differences between the two variables tested in the experiment, while the alternative hypothesis uses the experimental data in order to reject the null hypothesis. In this case, the alternative hypothesis will use the data from treatments 2 and 3 to confirm that predators can modify the behavior of mosquito larvae.
