Answer:
A
Explanation:
Gram positive bacteria stain violet due to the presence of a thick layer of peptidoglycan in their cell walls, which retains the crystal violet these cells are stained with.
The similarity in the arrangement and structure exists mostly with the quads because we, just like cats, need to be able to flex and extend them so we need a lot of strength in them.
Cohesion/adhesion - they help water act as if it were a "magnet"
Answer:
During the second half of glycolysis , <u>ATP is made</u> occurs .
Explanation:
Glycolysis -
In the first pathway of Glycolysis in the cytoplasm , it breakdowns the glucose to release energy .
Glycolysis has two parts -
In the first part , the six carbon moiety glucose break down to two three - carbon sugar moieties , in this process two molecule of ATP are invested .
In the second part , glycolysis extracts ATP and electron of high energy from the hydrogen atoms and gets attached to the NAD⁺ , in this process four ATP molecules are formed by the substrate phosphorylation .
Hence,
In the net process , Two molecules of ATP are formed .
Answer: Option A. "tetracyclines"
Explanation:
Tetracyclines are defined as a group of broad-spectrum antibiotics that are either isolated directly from several species of Streptomyces bacteria or can be synthesised semi-synthetically.
Tetracyclines act as inhibitors of growth rather than killing the infectious agent. Tetracyclines passively diffuse through porin channels present in bacterial membrane. it reversibly bind to the bacterial 30S ribosomal subunit to inhibit protein synthesis and prevents the aminoacyl transfer ribonucleic acid (tRNA) from binding to A site of the ribosome.
Hence, it is proved that tetracyclines bind to 30s ribosomal subunit rather than 50S ribosomal subunit in the ribososmes.
