Tmp/smx has two components that act on different steps in the folic acid biosynthesis pathway and are thus used together. sulfam

ethoxazole is a structural analog of a compound called paba, competing with it in the enzymatic production of dihydrofolic acid, an intermediate in the synthesis of folic acid. trimethoprim inhibits the step following dihydrofolic acid production and prevents the formation of the biologically active form of folic acid. choose true statements regarding tmp and smx.

Trimethoprim-sulfamethoxazole (TMP-SMX) are a class of antibiotics used in the treatment of bacterial infections due to their inhibitory actions in the folic acid biosynthesis pathway of bacteria.

<h3>What is TMP-SMX?</h3>

Trimethoprim-sulfamethoxazole (TMP-SMX), otherwise known as co-trimoxazole, is a combination of two antimicrobial agents that work synergistically to inhibit the enzyme systems involved in the bacterial synthesis of tetrahydrofolic acid.

They are used in the treatment of urinary tract infections, respiratory tract infections, cholera, etc.

They can be administered intravenously or orally.

Therefore, Trimethoprim-sulfamethoxazole (TMP-SMX) are antibiotics used in the treatment of bacterial infections.

The reason for the change in the hands of the chimpanzee include:

  • Crossbreeding between gorillas and chimpanzees( Represents a reason for the change)
  • Mutations in chimpanzee DNA ( Represents a reason for the change)
  • Differences in the ways chimpanzees use their hands ( Doesn't represents a reason for the change)
  • Sexual reproduction ( Doesn't represents a reason for the change)
  • Differences in enhancer sequences( Represents a reason for the change).

<h3>What is mutation?</h3>

Mutation is defined as the alteration in the genetic makeup of a living organism which may occur due to the following:

  • When there is spontaneous break down of deoxyribonucleic acid (DNA).
  • Change in a single nucleotide of the DNA.
  • when there is additions or deletions of nucleotide in a DNA strand.

A change can be noticed in an animal such as Chimpanzee when the following occurs:

Mutations in chimpanzee DNA: This can alter both that anatomy and the physiological features of the organism involved.

Crossbreeding between gorillas and chimpanzees: When there is cross breeding between a chimpanzee and a gorilla, it will lead to a genetic diversity which can be observed as a change in the hands of the chimpanzee.

Mila [183]

Answer:

The green buble

Explanation:

Antibiotics are added to the animal feed or drinking water of cattle, hogs, poultry and other food-producing animals to help them gain weight faster or use less food to gain weight.

Because all uses of antimicrobial drugs, animals contribute to the development of antimicrobial resistance, it is important to use these drugs only when medically necessary.

the production (e.g. growth enhancement) purposes as well as for the treatment, control or prevention of animal diseases. Even today, it is not entirely understood how these drugs make animals grow faster. The drugs are primarily added to feed, although they are sometimes added to the animals’ drinking water.

Mechanical stress applied to bone __________ osteoblast activity in bone tissue, and the removal of mechanical stress __________
iren2701 [21]

Mechanical stress applied to bone increases osteoblast activity in bone tissue, and the removal of mechanical stress decreases osteoblast activity.

Explanation:

Osteoblasts are cells , that are produced in the bone marrow and are responsible for formation of bones and bone matrix.

Whenever a mechanical stress is applied on the bones , a series of reactions are triggered. As a result the activities of osteoblast increases to synthesize more and more bone matrix to provide strength.

Again on the other hand a decrease in mechanical causes a decrease in the activities of the osteoblasts.
