Crystal structure is a description of the ordered arrangement of atoms, ions, or molecules in a crystalline material. The arrangement is three dimensional. The manner in which atoms, ions, or molecules are spatially arranged determines crystalline structure.

Unit cell: small repeating entity of the atomic structure. The basic building block of the crystal structure. It defines the entire crystal structure with the atom positions within.

FCC stands for face centered cubic. In fcc, atoms are arranged at the corners and center of each cube face of the cell. In one unit cell, 4 atoms are present and these atoms are assumed to touch along the face diagonals. In fcc lattice, the length of the edge of the unit cell is 400 pm.

The crystal structure is based on the Bravais lattice of the same name, with a single atom at each lattice point on the cube’s corners and faces. FCC is one of the most stable crystal structures and has the highest packing density.

For a fcc unit cell, the number of atoms per unit cell,

The joint, or articular, capsule of a synovial joint encloses the joint and prevents bone ends from being pulled apart.

The skeletal system of vertebrates is composed of stiff bones. They sustain the body's structural integrity, safeguard critical organs, and act as points of attachment for muscles, tendons, and ligaments. Living tissue makes up bones, which are constantly remodeling as old bone tissue disintegrates and new bone tissue is created.

An outer fibrous layer and an interior synovial layer make up the joint capsule, a fibrous structure that encircles the joint. The fibrous layer's strong connective tissue offers structural support and aids in preserving the joint's form. A thin membrane known as the synovial layer creates synovial fluid, which lubricates and nourishes the joint.

GnRH, or gonadotropin releasing hormone, is a protein hormone and not a steroid hormone.

Follicle-stimulating hormone (FSH) and luteinizing hormone (LH) are the two gonadotropic hormones released from the anterior pituitary by the releasing hormone known as gonadotropin-releasing hormone (or GnRH). GnRH is a peptide hormone which is produced and released by GnRH neurons in the hypothalamus. It is then supplied to the pituitary gland through the bloodstream.

The release of FSH and LH is controlled by parameters such as size, the frequency of GnRH pulses, and feedback from androgens and estrogens. FSH is released when low-frequency GnRH pulses are present, but LH pulse synthesis is simultaneously triggered by pulses of GnRH that are higher in frequency.

The correct answer is D. DNA polymerase. DNA polymerase is responsible for the elongation of DNA during replication.

During DNA replication, the double-stranded DNA molecule unwinds, and each strand acts as a template for the synthesis of a new complementary strand. DNA polymerase adds nucleotides to the 3' end of the newly synthesized strand, thereby extending it in the 5' to 3' direction. The energy for this process is derived from the hydrolysis of the high-energy phosphate bond in the incoming nucleotide triphosphate. DNA polymerase is capable of proofreading its own work and correcting errors that occur during replication. DNA ligase, on the other hand, joins the Okazaki fragments of the lagging strand during replication, and RNA polymerase synthesizes RNA during transcription.

A carotid cavernous fistula (CCF) is a type of abnormal connection between the carotid artery and the cavernous sinus. The carotid artery is one of the main blood vessels that supplies blood to the brain, and the cavernous sinus is a collection of veins located near the base of the skull.

When a CCF forms, blood from the carotid artery can flow directly into the cavernous sinus, causing increased pressure and a range of symptoms.

There are two main types of CCFs: direct and indirect. Direct CCFs occur when there is a direct connection between the carotid artery and the cavernous sinus, usually as a result of trauma or injury to the head or neck.

Indirect CCFs occur when there is an indirect connection between the two structures, usually as a result of a congenital defect or a weakening of the blood vessel walls.

Symptoms of CCFs can include bulging eyes, double vision, redness or swelling of the eye, and vision loss.

As a result, around 4% of persons in the United States are cystic fibrosis carriers.

Cystic fibrosis (CF) is a genetic disorder that affects mainly the lungs, pancreas, and digestive system. It is caused by mutations in the cystic fibrosis transmembrane conductance regulator (CFTR) gene, which encodes a protein that regulates the flow of salt and fluids in and out of cells. In people with CF, the CFTR protein is either absent or malfunctioning, leading to thick, sticky mucus buildup in the airways and pancreas. This can cause a range of symptoms, including chronic lung infections, coughing, wheezing, shortness of breath, and digestive problems such as difficulty digesting food and absorbing nutrients.

Here,

The Hardy-Weinberg equilibrium equation relates the frequencies of alleles and genotypes in a population, and can be used to predict the frequencies of carriers for a recessive disease like cystic fibrosis.

Let's use the following notation to represent the alleles for the cystic fibrosis gene:

Let p be the frequency of the normal (non-disease) allele.

Let q be the frequency of the disease allele.

Since cystic fibrosis is a recessive disease, individuals with two copies of the disease allele (qq genotype) will be affected, while individuals with one copy of the disease allele and one copy of the normal allele (pq genotype) will be carriers. Individuals with two copies of the normal allele (pp genotype) will not be affected and not be carriers.

According to the problem statement, the frequency of the q allele (the disease allele) is:

q = √(1/2500) = 0.02

The frequency of the p allele can be found by subtracting the frequency of the q allele from 1:

p = 1 - q = 1 - 0.02 = 0.98

Now, we can use the Hardy-Weinberg equation to calculate the expected frequencies of the three genotypes:

p² = frequency of pp genotype (non-carriers)

2pq = frequency of pq genotype (carriers)

q² = frequency of qq genotype (affected)

The frequency of carriers (pq genotype) is:

2pq = 2 x 0.98 x 0.02 = 0.0392

To convert this to a percentage, we can multiply by 100 and round to the nearest whole number:

0.0392 x 100 ≈ 4

Therefore, approximately 4% of people in the United States are carriers for cystic fibrosis.

Opioid receptors are transmembrane proteins. Opioid receptors fall within the category of G protein-coupled receptors (GPCRs), a class of proteins.

Opioid receptors are found in the nervous system and are housed in the outer membranes of nerve cells (neurons). When opioids engage (bind) to the receptors, a series of chemical changes within and between neurons are triggered by the contact, producing feelings of pleasure and pain relief.

Opioid receptors are expressed in the locus coeruleus, periaqueductal grey area, and other descending circuits that influence pain. Opioid receptors are an inhibitory G protein-coupled receptor type that respond to opioid ligands. Examples of endogenous opioids include nociception, enkephalins, endorphins, and dynorphins.

All three of the G protein-coupled receptor (GPCR) family's opioid receptor subtypes, which are made in cell lines, mediate how opioids inhibit adenylyl cyclase activity (2–5).
