Chronic hepatitis is usually caused by contaminated needles due to drug use or sexually transmitted disease. Acute hepatitis is usually caused by the hepatitis A infection due to poor living conditions.
Answer:
b. Clostridium botulinum.
Explanation:
The enterotoxins (also know as exotoxins when they are produced by bacteria) are polypeptides secreted by microorganisms that target the intestine. These toxins may produce serious damage to the host by disrupting the function of the epithelial intestinal cells Moreover, <em>Clostridium botulinum </em>is a Gram-positive bacterium that is able to produce a potent neurotoxin (botulinum) which is known to cause severe flaccid paralytic deformities in humans.
Birds live virtually everywhere on Earth because they have evolved endothermy, the ability to use their metabolism to maintain a constant body temperature.
Birds belong to the class aves; they have an extremely efficient, one way breathing system with additional air sacs. Flying birds have strong, hollow bones and powerful flight muscles. Most birds can fly, they have a strong heart and an efficient way of breathing; which are necessary for birds to fly.
It could be Infectious Arthritis. It happens when an infection, caused by a bacteria, spreads to the joint or the fluid surrounding it.

Please find the explanation below
Explanation:
Photosynthesis is the process whereby plant cells manufacture their energy source or food (glucose) in the presence of sunlight. Cellular respiration, on the other hand, is the process by which living cells release energy in form of ATP needed by their cells for cellular activities.
Living organisms eat or obtain take in food in order to obtain energy for their cellular upkeep. Plants are one of the only set of organisms that can produce their own food i.e. autotrophic and they do so via PHOTOSYNTHESIS. However, they need to undergo cellular respiration in order to breakdown the synthesized food to yield usable energy for their cells. These two processes in plants are direct metabolic opposite of one another.
Based on the explanation above, plants need to use both PHOTOSYNTHESIS AND CELLULAR RESPIRATION because the products of one yields reactant for the other. photosynthesis uses carbon dioxide released by cellular respiration while cellular respiration uses oxygen released by photosynthesis.
