Regulating hormones from the hypothalamus first enter into the hypophyseal portal system.
<h3>Are hormones regulated by the hypothalamus?</h3>
The hormones produced by the hypothalamus and secreted by the neurohypophysis are antidiuretic hormone and oxytocin. Antidiuretic hormone promotes an increase in urine concentration, as it ensures greater reabsorption of water by the kidneys.
It is the hypothalamus that produces the antidiuretic hormone and oxytocin, which will be secreted by the neurohypophysis.

Answer:
The correct answer will be- zygote →cleavage→ morula→ blastula→ gastrula.
Explanation:
Human embryogenesis is the study of the formation of an embryo from the zygote formed after the fertilization of the sperm and egg cell.
The fertilization takes place in the ovarian duct in females which form a diploid zygote. The zygote starts the process of cleavage that is cell division and differentiation and leads to the formation of a 2 celled stage, 4 celled stages and later 16 celled stage. The 16 celled stage is known as morula which further undergoes cleavage and form blastula. The blastula now forms a gastrula with 3 layered distinction- the ectoderm, endoderm and mesoderm through gastrulation.
Thus, zygote →cleavage→ morula→ blastula→ gastrula is the correct answer.
D, they make the energy and the energy level only gets smaller the higher you get.
B. microorganisms is the answer
Answer:
Many traits unique to the human lineage were long thought to have originated between 2.4 million and 1.8 million years ago in Africa. These include a large brain and body, long legs, reduced differences between the sexes, increased meat-eating, prolonged maturation periods, increased social cooperation and tool making.
