Answer:
During interphase, the cell grows and the nuclear DNA is duplicated. Interphase is followed by the mitotic phase.
During interphase the cell grows and the nuclear DNA is duplicated. Interphase is followed by the mitotic phase, the duplicated chromosomes are segregated and distributed into daughter nuclei. The cytoplasm is usually divided as well resulting in two daughter cells
Answer:
The correct answer would be c. pupil.
Pupil refers to the adjustable opening present at the center of the iris.
It appears as a black hole present at the center of the eye through which light is passed into the eye.
The iris is muscular and contractile structure present around the pupil.
The pupil regulates or controls the amount of light entering the eye with the help of iris.
Iris through its contractile nature regulates the size of the pupil and thus, it controls the amount the light passing through the eye.
The adjustable opening in the center of the eye controlling light entry is the pupil, with size adjustments regulated by the iris.
The adjustable opening in the center of the eye that helps control the amount of light entering the eye is called the pupil. This integral part of the eye widens or narrows to allow more or less light to enter, respectively. The pupil's size is regulated by the surrounding muscle structure, the iris, which adjusts depending on the intensity of light present. Unlike the cornea and fovea, which have different roles, the pupil specifically controls light entrance.

The pancreas produces the peptide hormone known as human insulin, which is essential for controlling blood sugar levels. There are two peptide chains in it, joined together by disulfide bonds.
An "A" chain and a "B" chain are the two peptide chains that make up human insulin. The A and B chains' amino acid sequences are arranged as follows:
A Chain (21 amino acids):
GIVEQCCTSICSLYQLENYCN
B Chain (30 amino acids):
FVNQHLCGSHLVEALYLVCGERGFFYTPKT
The 51 amino acids of human insulin make up the entire protein. Human insulin has a molecular mass of around 5808 Da (Daltons).
Dimer: Since human insulin is made up of two peptide chains (A and B chains) connected by disulfide bonds, it is a dimer.
Peptide Chains: The A chain and the B chain are the two peptide chains that make up human insulin.
Location: The beta cells of the pancreatic islets of Langerhans generate and secrete human insulin.

Human insulin is a peptide hormone consisting of 51 amino acids across two chains. The primary amino acid sequence of chain A includes Gly, Ile, Val, and others. Insulin, a dimer, circulates in the bloodstream and binds to insulin receptors on cells.
The protein of interest I will elaborate on is human insulin. Insulin is a peptide hormone produced by beta cells in the pancreas. It has a total of 51 amino acids divided into two peptide chains linked by disulfide bridges, Chain A and Chain B. Chain A has 21 amino acids while Chain B has 30.
The primary amino acid sequence of chain A of human insulin starts with: Gly, Ile, Val, Glu, Gln, Cys, Cys, Thr, Ser, Ile, Cys, Ser. The molecular mass of insulin is approximately 5808 Da.
Insulin is a dimer in its storage form but functions as a monomer when it is actively binding to receptors. As it is a hormone, it circulates in the bloodstream and binds to insulin receptors on cells to promote glucose uptake.
