A feedback mechanism is a physiological control system in a living organism that functions to bring the body back to its stable internal condition, also referred to as homeostasis.
When a change in the system results in an output, the feedback mechanism is activated. Chemicals, genes, and the regulatory relationships between them make form the biochemical control system in living things.
There are two types of feedback mechanisms; these are positive and negative feedback mechanisms.
When a change in one direction is followed by another change in the same direction, positive feedback loops develop.When a change in one direction results in a change in the other, negative feedback loops are created. For instance, feedback results from an increase in a substance's concentration, which lowers the substance's content. Mechanisms called negative feedback loops appear to be stable by nature.Feedback loop for dehydration.
A stimulus is reversed or turned off by negative feedback. Antidiuretic hormone, which acts to reduce urine production and enable the body to save fluids, is secreted when the body is dehydrated. Negative feedback stops the release of the antidiuretic hormone when the body's fluids are replenished.

What is plasma ?Of the four basic states of matter, plasma is one. It comprises a substantial amount of ions and/or electrons, which are both types of charged particles. The main distinction between plasma and the other elementary forms of matter is the presence of these charged particles. Being largely linked to stars, such as the Sun, it is the most prevalent type of ordinary stuff in the universe. It reaches to the rarefied intracluster medium and perhaps even to areas outside of our galaxy. Heating a neutral gas or exposing it to a powerful electromagnetic field can produce plasma artificially.
Plasma is electrically conductive due to the existence of charged particles. Individual particle dynamics and macroscopic plasma motion are controlled by collective electromagnetic fields, and both are extremely sensitive to externally imposed fields.

Suppose you provide an actively dividing culture of e. Coli with radioactive thymine. What would you expect to see if the cell replicates its dna and divides once in the presence of the radioactive base?.
Suppose you provide an actively dividing culture of E. coli with radioactive thymine. If the cell replicates its DNA and divides once in the presence of the radioactive base then e. DNA in both daughter cells would be radioactive.
An E.coli divides itself into two daughter cells by splitting in two cells after the process of mitosis. If an actively dividing E.coli cell is treated with radioactive thymine, then we can infer that the radioactive base has been incorporated in its DNA if it is found in both the daughter cells of the actively dividing E.coli cell.
We will see the radioactive thymine in both the daughter cells because of the process of division of E.coli is mitosis as a result of which the parent and daughter cells formed are all genetically identical and copies of each other.

The defects we will most likely see in the mutant E.coli are C. a delay in DNA polymerase beginning the synthesis and D. a longer total time to replicate DNA.
The primase plays a crucial role in DNA replication as they are involved in the formation of primers. These primers are short RNA sequences that initiate transcription.
A mutation is a change in the DNA sequence. A mutation in the primase activity of E.coli will cause a delay in the process of replication, as without the formation of primers, DNA polymerase will delay its activity to synthesize a new strand by the addition of nucleotides. On the whole, it will take much longer for the replication process as the activity of DNA polymerase will take much longer.

d. 6.50-7.50.
The correct answer is [c] 7.35-7.45
The normal range of pH of arterial blood pH 7.35-7.45.
What do you mean by arterial blood?Three different tests—pH, Pco2, and Po2—are typically taken in conjunction to assess the patient's acid-base state, ventilation, and arterial oxygenation. This group of measurements is referred to as arterial blood gases (ABGs). The most significant respiratory gases are oxygen (O2) and carbon dioxide (CO2), and the partial pressures of these gases in arterial blood indicate how well gas exchange is functioning generally.
Age and altitude have an impact on Pao2. Paco2 by height. As a result, Pao2 needs to be determined specifically for each patient, and both results need to be compared to the neighborhood's norms. Because hydrogen is not a gas in blood, it does not impose a partial pressure. However, every arterial blood gas determination includes pH, which assesses hydrogen ion activity. Blood pH should fall between 7.35 and 7.45.
The ABGs may include certain calculated or derived variables. The most helpful of these is the bicarbonate concentration, which may be determined from the pH and Pco2. Others are not necessary and could be confusing, such as base excess and base deficiency.

Every enzyme has a different specific heat.
The amount of heat needed to raise a substance's temperature by one degree Celsius in one gramme is also known as specific heat. Typically, calories or joules per gramme per degree Celsius are used as the units of specific heat. For instance, water has a specific heat of 1 calorie (or 4.186 joules) per gramme per degree Celsius.
The notion of specific heat was developed by the Scottish scientist Joseph Black in the 18th century as a result of his discovery that equal masses of different substances required varying quantities of heat to raise them through the same temperature range. The French scientists Pierre-Louis Dulong and Alexis-Thérèse Petit showed in the early 19th century that measurements of a substance's specific heat allow one to calculate its atomic weights.
