Answer:
Antibiotics inhibit enzymes specific to bacteria and have no effect on virally encoded enzymes
Explanation:
The specificity of the antibiotics to inhibits some bacterial enzymes is one of the major reasons why antibiotic do not affect viruses.In addition antibiotics are designed to have a significant destructive effects on the mechanisms of biochemical reactions in bacteria and its physiology, e,g on the cells walls,( inhibiting the formation of peptydoglycans) on certain organelles e,g ribisomes (inhibiting protein synthesis) and on the DNA(disrupting replication). The virus physiology is different from bacteria, therefore the design of antibiotics will nor affect these same mechanisms in viruses, thus no specificity for the antibiotic to act on in virus

Explanation:
Spinal nerve divides into several branches after passing through its intervertebral foramen. These branches are called rami. A spinal nerve gives off several branches such as anterior ramus, posterior ramus, rami communicantes, and a meningeal branch. The meningeal branch reenters the vertebral cavity through the intervertebral foramen. It serves to supply the vertebrae, vertebral ligaments as well as the blood vessels of the spinal cord, and meninges.

The answer is; D
Archaebacteria are early life forms on earth. They utilized the process of chemosynthesis to make organic molecules from inorganic molecules and for energy. The word archae means ‘ancient’ life forms. These single-celled organisms evolved around sulfur-rich environments of the hydrothermal vents.
