The thyroid-stimulating hormone will be stimulated if estrogen does not activate the hypothalamus.
What is the hypothalamus?The hypothalamus is the part of the brain that secretes hormones to control the function of the body's organs and cells. The most important function of the hypothalamus is homeostasis, which ensures and maintains all body systems running stable.
The hypothalamus releases hormones to another part of the brain, namely the pituitary gland. This gland will then send these hormones to various other organs of the body.

There are two sources of blood flow for the liver. The hepatic artery, which transports oxygenated blood from the systemic circulation, is the first. The second is the hepatic portal vein, which transports nutrient-rich, deoxygenated blood from the small intestine.
The blood that supplies the liver with the nutrients and oxygen it requires comes from two significant blood vessels: the portal vein. liver artery. Liver Bile, a digestive fluid produced by the liver, aids in the breakdown of lipids and several vitamins. The small intestine or your gallbladder receive bile from your liver for storage or usage via bile ducts.

two fruit flies have different parents. one fruit fly has orange eyes while the other has red eyes. why do the fruit flies have different eye colors?
Fruit flies have different eye colors because the fruit flies have many eye colour genes that direct different proteins to interact in various ways to produce a variety of eye colours.
What is the role of genes in variation?
The genetic composition of organisms within a population change is referred to as genetic variety. Genes are inherited sections of DNA that contain the instructions needed to make proteins. Alleles, which are different forms of a gene, determine certain features that can be transferred from parents to kids.
Natural selection and biological evolution are processes that depend on genetic variety. Natural selection does not take place, but genetic variants that develop in a population do.

Which structure packages and transports materials out of the cell?
A certain gene codes for a polypeptide that is 120 amino acids long. Approximately how many nucleotides long is the mrna that codes for this polypeptide likely to be?.
When a gene encodes a polypeptide containing 120 amino acids, 360 nucleotides are required in the mRNA to encode that polypeptide.
Each codon of the mRNA molecule consists of 3 nitrogenous bases because it is called a triplet, and each nucleotide consists of 1 nitrogenous base, 1 pentose sugar, and 1 phosphate so if there are 3 nitrogenous bases it can be said that there are also 3 pentose sugars and 3 phosphates which produce 3 nucleotides at each codon. So that it can be concluded that each codon consists of 3 nucleotides.
Thus, each amino acid is defined by three consecutive nucleotides (i.e., codons) so that if there are 120 amino acids, it is defined by 360 nucleotides (120 x 3 = 360 nucleotides).
