Neurons in the hypothalamus regulate the activity of secretory cells in the anterior pituitary gland by releasing hormones. Pituitary gland basically store the hormones which is produce by the hypothalamus.
Hypothalamus connect the nervous and endocrine systems by way of the pituitary gland. Both are connected directly to the pituitary gland by a thin stalk which is called infundibulum.
Its main function is to secrete releasing hormones and inhibiting hormones that stimulate the production of hormones in the anterior pituitary. FSH and LH both are produce and secret gonadotropins which regulated by the hypothalami releasing hormone, GnRH. These are the releasing hormones which control the release of another hormone.

C. The cell must be a plant cell.
Only plant cells have cell walls. Bacteria cells and animal cells do not. Both animal cells and plant cells have membrane-bound organelles, but since the student saw a cell wall, it must be a plant cell.
Hope this helps! :)
Answer:
When we talk about the inheritance of traits, or the passage of traits from parents to future generations down the line, we are not just talking about the visual (phenotypical) expression of those traits, but also, their underlying explanation, which is the genotype. A genotype is basically how the genes of the parents combine in such a way that the children inherit a set of traits from the parents, and express them phenotypically, or not.
In the case of blood types, we have four phenotypic groups: A, B and O. Each one of these types is characterized by the underlying set of genes that are responsible for what is expressed. While the O blood type presents a genotype ii, which is recessive, the A and B types will have the following genetic patterns: Ia Ia, or, Ia i (characteristic of the O genetic material) for the A type and: Ib Ib, or Ib i, for the B type. When there is a genetic conjugation from parents genetic material, regarding blood type, we would have these sets of genes combining. In most of the possible combinations genetically speaking, we have the recessive i gene appearing, including in the A and B dominant blood types. This means that when crossed, there will always be a chance of at least one offspring presenting the O blood type, even if one of the parents is dominant A, or B.
In answer: it is the fact that all three types present the recessive allele i, typical of the O blood type, that when pairings of genes happen between parents, the genetic characteristic of the O type may present itself in a dominant fashion, instead of the usual recessive pattern.
