Melatonin exerts its inhibiting effect in the hypothalamus by reducing the gonadotropin-releasing hormone (GnRh). This hormone is responsible for the creation of estrogen in the ovaries and testosterone in the testes.
Hope that helps!

Simple cuboidal epithelium is a type of epithelium that consists of a single layer of cuboidal cells. These cuboidal cells have large, spherical and central nuclei. This type of tissue is found lining parts of organs and ducts in the body. its structure allows for absorption and diffusion in those areas. Mostly found in organs that are specialized for secretion, such as salivary glands ( part of the digestive tract) and thyroid follicles, and those that are specialized for diffusion, such as the kidney tubules.
Answer:
One of the probable ways to determine how long ago any two species of bacteria diverged from each other is by drawing a phylogenetic tree.
Explanation:
- Phylogenetic tree are trees that show the ancestry of two species of interest and the relationship between them.
- The idea behind the construction of phylogenetic tree is darwins's "descent with modification theory".
- A phylogenetic tree is constructed using the similarities or differences in either physical characteristics, behavorial, or genetic buildup.
- Derived traits shared between the different species are the actual data used to construct a phylogenetic tree.
Okay well the signal or the movement coming through the neuron(and its axon) is about the ions. The ion is a charged like particle, such as Na+ (If you remember that). Na+ is a sodium ion. So most of those ions I was talking about before just simply flow in or out of the cell. I hope this helps! <3
