Feedback inhibition is the enzyme function in this scene

Feedback inhibition is an essential biochemical process that modulates several enzymatic reactions using noncompetitive inhibitors. The final product of this process blocks the enzyme that catalyzes the first series of reactions. Synthesis of some amino acids is regulated by feedback inhibition. A simple example of feedback cancellation is a thermostat connected to a heater. A sensor detects the temperature in the that room, and when the temperature was reaches a predetermined set of point, the thermostat was signals the stove to turn it off. Feedback inhibition occurs when there end product of the reaction interferes with the enzyme that actually helped produce it. Inhibitors do this by the binding to the second active binding site that is actually different from that bound to the first and the reactant. The enzyme then changes shape and can no be longer catalyze the reaction

The mechanism causes the movement of phloem sap from sources to sink tissues that would be differences in the source-sink pressure potential according to the pressure-flow hypothesis.

As a result of the high turgor pressure, phloem sap is transported by "bulk flow" from the source to the sink, where the sugars are quickly eliminated from the phloem. The rise when the sugar is removed, causes the water to leave the phloem and return to the xylem, lowering the p.

Phloem sap moves through phloem via translocation, the transport of dissolved materials in a plant, which is triggered by high turgor pressure and occurs from source to sink. Phloem carries sap both upward and downward, from sugar sources to sugar sinks, unlike the xylem, which can only carry water upward. It is suggested that the phloem is a conduit through which pressure-containing water-carrying food molecules flow.

In an important experiment with e. Coli, Mseason and Stahl hooked up that in DNA replication, every one of the 2 strands that make up the double helix had been used as a template for the new strands of DNA to just take the test.

The presence of 1 parental subunit for every daughter DNA double helix supported semi-conservative replication. The 1/3 conclusion made with the aid of Meselson and Stahl said that for every parental DNA molecule,  new molecules were made. consequently, the quantity of DNA after each replication is elevated via an issue of two.

Meselson & Stahl reasoned that these experiments confirmed that DNA replication changed into semi-conservative: the DNA strands separate and everyone makes a copy of itself so that each daughter molecule accommodates one "vintage" and one "new" strand.

Macrophages arise from monocytes. Therefore, the first option (monocytes) is the correct answer.

Monocytes are a type of white blood cell that carry out phagocytosis and destroy antigens. They are the largest white blood cells and are involved in innate immunity.

This type of immune cell circulates through the blood for 1–3 days and then migrates to the tissue. In the tissue, they differentiate into dendritic cells and macrophages.

These macrophages help detect and degrade dead cells, tumor cells, and foreign materials.  Macrophages are large phagocytic cells. But they are smaller compared to monocytes. They are specialized cells, so they don't differentiate.

The topmost coat of many different types of viruses is called a viral envelope. When moving between host cells during their life cycle, it safeguards the genetic material. Not every virus has an envelope. Even though some viral glycoproteins are present, the envelopes are typically made from remnants of the host cell membranes. This envelope is produced by a process known as "budding off" from the infected cell, or host. Newly formed virus particles are "enveloped" or wrapped in an outer layer made of a small fragment of the cell's plasma membrane during the budding process.

Answer:

Haploid cells have only one set of chromosomes due to meosis.

Explanation:

Gametes are sex cells.

Gametes contain half the chromosomes contained in a normal diploid cell.

Gametes are produced as a result of meiosis.

During meiosis, the chromosome number is reduced to half and each daughter cell receives half the set of chromosomes.

These gametes unite together to form a zygote.

If both the gametes were diploid, the zygote will have double the number of chromosomes of somatic cells, which in turn results in an abnormal organism.

Thus, gametes have a haploid number of chromosomes.
