Answer:

An antibiotic is a type of antimicrobial substance active against bacteria. It is the most important type of antibacterial agent for fighting bacterial infections, and antibiotic medications are widely used in the treatment and prevention of such infections. They may either kill or inhibit the growth of bacteria. Antibiotics DO NOT work on viruses, such as those that cause: Colds and runny noses, even if the mucus is thick, yellow, or green. Most sore throats (except strep throat) Flu.

Answer:

Antibiotics are medicines that help stop infections caused by bacteria. They do this by killing the bacteria or by keeping them from copying themselves or reproducing. Antibiotics do not work on viruses, such as those that cause colds, flu, bronchitis, or runny noses, even if the mucus is thick, yellow, or green. Antibiotics are only needed for treating certain infections caused by bacteria, but even some bacterial infections get better without antibiotics.

Explanation:

-The Retina

The retina is a thin, transparent layer at the periphery of the eye's interior. Light enters the eye and is detected by specialized neural cells. The light is converted into an electrical impulse, by photosensitive rods and cones. This impulse is transmitted and interpreted by the central nervous system or CNS.

Further Explanation:

The nervous system is subdivided into; the central nervous system (CNS), which includes the brain and spinal cord, within the vertebral column; and the peripheral nervous system, which includes nerves that branch into the rest of the body from the brain and spinal cord. Nervous tissue responds to electrical impulses, allowing for communication between different regions of the body.

The peripheral nervous system is further divided into the somatic nervous system responsible for carrying out sensory and motor information between the peripheral nervous system- including sensory organs like the eyes; and central nervous system;

prisoha [69]

Answer:

Concentration gradient means difference in solute concentration among two regions of a solution.

Explanation:

When there is a difference in solute concentration in the two regions of a solution then the term concentration gradient is used .

Various membrane transport process such as passive transport(diffusion and osmosis),facilitate transport depends on concentration gradient of solute molecule in both sides of plasma membrane.

During passive and facilitate diffusion solute molecules are transported along their concentration gradient that means from high concentration region to the region of low concentration until equilibrium is being established.
