D) All the Above.

There are diseases that are carried from one person to another by sharing the same food, water and body fluids. If an infected person shares food with a non infected person the germs and bacteria that are present on his hands will carry the disease. There are several diseases that are water borne. These are spread through poor sewage systems or the water droplets in the air in which an infected person breathes. Body fluids can be the mucus from the nose of the flu, the spit of an infected person or sexual discharge that can cause STDs to a non infected person.

What contributes to waste management by recycling metabolic products and converting toxic substances into less toxic ones
kompoz [17]

The kidneys contribute to waste management by recycling metabolic products and converting toxic substances into less toxic ones.

Kidneys are an important organ of animals as they provide a channel for the disposal of body waste and simultaneously regulate the balance in the level of salt and water in the body.

Kidneys work as microfilters that are capable of eliminating dissolved and suspended forms of ammonia, uric acid, urea, creatine, creatinine, amino acids, excess salts, and water along with proper disposal of organic waste which altogether constitutes the metabolic waste of the body. These substances before being finally excreted from the boy undergo a last round of reabsorption.

Where do prions come from?
Musya8 [376]

Answer:

There are prion-like particles in the brain normally, and when these become abnormal they can cause disease. (Ans. A)

Explanation:

Prions are proteins which can trigger normal proteins to fold abnormally, and they are present in the brain. They are causing many types of neurodegenerative diseases in both humans and animals. Which are known as transmissible spongiform encephalopathies.

Prions can enter the brain with the help of infection, also can arise from the gene mutation that encodes the proteins, and sometimes this affects humans by infected meat.

If a person infected from prion disease, it affects central nervous system tissues like brain, eye tissues and spinal cord.
