Answer:

<u>Option-(True):</u> The following statement is true in all sense, as the "Cytotoxic T cells and NK cells kill by secretion of proteins. The first called granzyme which forms complexes that penetrate the cell membrane and allows the passage of the apoptosis inducing protein perforin to enter the targeted cell."    

Explanation:

  • In order to make it more difficult for the pathogens and other foreign particles to stay inside the human body, the defense mechanism of the human body system has evolved itself to great extents as there are different level of immune layers and more over cells that either helps in the recognition of these anti-bodies or attacks them to be eliminated from the given system.
  • As the hazardous or cancer cells which are not required to stay inside the human body is removed with the help of these lymphocytes inside the immune system of the human body.

Pie

Dab most likely inhibits phosphorolysis of glycogen reaction.

<h3>What is phosphorolysis?</h3>
  • Inorganic phosphate acts as the attacking group during phosphorolysis, which is the cleavage of a molecule.
  • It's comparable to hydrolysis.
  • A reversible process akin to hydrolysis where phosphoric acid behaves like water and produces phosphate as a byproduct.
  • It's comparable to hydrolysis.
  • Glycogen phosphorylase, which catalyzes the assault of inorganic phosphate on the terminal glycosyl residue at the nonreducing end of a glycogen molecule, is an example of this.
  • The difference is that while reactions involving hydrolysis use water to split larger molecules into smaller ones, reactions involving phosphorolysis use phosphate to achieve the same result.
  • The primary enzyme in utilizing the glycogen reserves in the muscle and liver is known as glycogen phosphorylase.
  • It catalyzes the sequential phosphorolysis of glycogen to liberate glucose-1-phosphate.

A science teacher wants to use a line graph to model the relationship between the concentration of CO2 in the atmosphere and the
natali 33 [55]

Answer:

A)

global temperature increasing as CO2 concentration increases

Explanation:

Global warming is the progressive increase in the temperature of the earth's atmosphere. Global warming is caused by an increase in the concentration of greenhouse gases e.g CO2, chlorofluorocarbons etc. These greenhouse gases, in which carbondioxide is an important example, are capable of trapping heat in order to keep the earth warm.

Howeever, as the concentration of CO2 and other greenhouse gases increase in the atmosphere, the earth's atmospheric temperature also increases above normal, causing Global warming.

In this case, the science teacher's graph will show that global temperature is increasing as CO2 concentration increases.

Part a - bacterial cell wall peptidoglycan is a polymer of millions of n-acetylglucosamine (nag) and n-acetylmuramic acid (nam)
LekaFEV [45]
I believe the appropriate answer is, short amino acid chains, NAG, NAM, and some lipid proteins.
Peptidoglycan is also known as Murein, it is a polymer consisting of sugars and amino acids that form a mesh-like layer outside the plasma membrane of most bacteria, forming the cell wall. The sugar component consist of alternating residues of β-(1,4) linked N-acetylglucosamine (NAG) and N-acetylmuramic acid (NAM),
