Answer:
Explanation:
Electric field is a vector quantity whose direction is defined as the direction that a positive test charge would be pushed when placed in the field. Thus, the electric field direction about a positive source charge is always directed away from the positive source.
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.
Answer:
A) Occipital bone
Explanation:
Based on the scenario being described it can be said that the structure best demonstrated would be the occipital bone. This is a bone that forms in the base of the skull towards the back and around the spinal cord. Since the AP axial position projects the anterior structures downward, then it would allow for the occipital bone to be easily viewed without special equipment.
Frontal lobe
Frontal lobe is situated near the front of the head and it is the most forward of the four lobes of the cerebral cortex. The frontal lobe is the area responsible for primary motor functions and some of the most complex cognitive processes such as memory, problem solving, sexual behaviors, emotional expression, language, and judgment.
