It takes for the body to get rid of each drink in an average adult 2 hours. So the correct answer is c.

The liver processes alcohol at a fairly consistent rate of about one standard drink per hour, regardless of factors such as gender, weight, or ethnicity. Therefore, if an average adult consumes one standard drink, it takes about two hours for their body to eliminate it. However, it's important to note that consuming more than one drink in an hour can result in a buildup of alcohol in the bloodstream, leading to impaired judgment and coordination, and potentially dangerous levels of intoxication.

When we consume alcohol, it enters the bloodstream and is transported throughout the body, affecting various organs and bodily functions. However, the liver is primarily responsible for processing and eliminating alcohol from the body.

The liver breaks down alcohol into acetaldehyde, a toxic substance that can cause damage to cells and tissues. Acetaldehyde is then broken down further into acetate, which is eventually eliminated from the body as carbon dioxide and water.

In this scenario, the 56-year-old woman was brought to the emergency department due to various symptoms, and her lab studies showed increased levels of cardiac troponin I in her blood.

Based on the given scenario, the patient is experiencing symptoms of a possible cardiac emergency. The elevated cardiac troponin l in the blood suggests damage to the heart muscle, which could be due to a myocardial infarction (heart attack).

In this case, the protein was most likely released from the sarcoplasmic reticulum, which is responsible for calcium storage and release during muscle contraction in cardiac muscle cells.

It is important to promptly diagnose and treat this emergency to prevent further damage to the heart and other organs.

By bicarbonate system the majority of carbon dioxide produced by cellular metabolism carried in the blood on its way to the lungs to be exhaled.

Three mechanisms exist for transferring carbon dioxide through the blood. It is either immediately dissolved in the blood, attached to haemoglobin or plasma proteins, or transformed into bicarbonate. As part of the bicarbonate system, the majority of carbon dioxide is transferred.

Bicarbonate ions are the main form in which carbon dioxide is transferred. This is due to the high activity of the enzyme carbonic anhydrase in erythrocytes, which catalyses the reaction between carbon dioxide and water.

The blood carries carbon dioxide to the lungs, where it is eventually expelled from the body by breathing. The human body uses carbon dioxide for a variety of functions, including regulating blood pH, driving the respiratory system, and increasing hemoglobin's affinity for oxygen.

The answer is (d) temporary. Temporary hair color only coats the surface of the cuticle and does not penetrate the cortex.

Temporary hair color sits on top of the hair shaft and doesn't change the natural hair color. It can be washed out easily and typically lasts only a few washes. Because it doesn't penetrate the hair shaft, it's less damaging to hair than permanent or semi-permanent hair color. Temporary hair color can be a good option for those who want to experiment with a new hair color without committing to a permanent change.

The factor that should limit biological activity in the biochemical oxygen demand (BOD) test is oxygen. This test measures the amount of oxygen required by microorganisms to break down organic matter in a sample of water. The higher the BOD, the more organic matter there is in the water, and the more oxygen is required for the microorganisms to break it down. Therefore, if there is not enough oxygen available, the biological activity will be limited and the BOD will be lower.

The cardinal ligaments are paired structures that provide support to the cervix and uterus. Here option C is the correct answer.

In an abdominal hysterectomy, these ligaments are encountered and ligated last, after the uterus has been removed. This is because the surgeon must first dissect the bladder and ureters away from the cervix and vagin* to avoid injury, and then the cardinal ligaments can be identified and ligated.

In contrast, in a vagin*l hysterectomy, the surgeon approaches the uterus from below, and the cardinal ligaments are the first structures encountered and ligated. This allows the surgeon to mobilize the uterus and cervix and facilitate their removal through the vagin*l canal.

The round ligaments are paired structures that attach the uterus to the labia majora and are not typically encountered or ligated in a hysterectomy. The uterosacral ligaments provide support to the posterior aspect of the cervix and are usually ligated during a vagin*l hysterectomy.

Transcytosis is the mechanism whereby peptides, bicarbonate, and enzymes can be absorbed.

Transcytosis is a process by which substances are transported across a cell by endocytosis on one side and exocytosis on the other side. It involves the formation of vesicles that internalize the substances from the extracellular space and transport them across the cell to release them on the other side.

Peptides, which are short chains of amino acids, can be absorbed through transcytosis. They are often transported across the epithelial cells of the intestines, allowing for the absorption of dietary proteins.

Bicarbonate, an important ion involved in maintaining the acid-base balance in the body, can also be transported through transcytosis. Bicarbonate is produced in certain cells, such as pancreatic cells, and is transported across the cell membrane to be released into the bloodstream or other target tissues.

Enzymes, which are proteins that catalyze biochemical reactions, can undergo transcytosis to be transported to specific locations within the body. For example, certain digestive enzymes produced in the pancreas are transported via transcytosis to the small intestine, where they play a role in the breakdown of food.

During the elongation cycle of translation, the A site on a ribosome functions in receiving a new tRNA with the correct amino acid. Elongation is the second stage of translation, where the ribosome moves along the mRNA strand, adding amino acids to the growing polypeptide chain.

The ribosome has three binding sites for tRNA molecules: A site (aminoacyl site), P site (peptidyl site), and E site (exit site). The A site is where the incoming tRNA carrying the next amino acid in the sequence binds to the ribosome. The correct tRNA molecule must have an anticodon that is complementary to the codon on the mRNA. Once the tRNA is bound to the A site, the ribosome catalyzes the formation of a peptide bond between the amino acid on the tRNA in the A site and the growing polypeptide chain on the tRNA in the P site.

Then, the ribosome translocates along the mRNA, moving the tRNA from the A site to the P site, and the tRNA from the P site to the E site. The A site is now open and available for the next tRNA molecule to bind and start the process again. This cycle continues until a stop codon is reached, and the completed polypeptide is released from the ribosome.
