Answer:
Virulence, the capacity to cause disease, varies markedly among viruses. Some viruses cause lethal disease while others do not. For example, nearly all humans infected with rabies virus develop a disease of the central nervous system which ultimately leads to death. In contrast, most humans are infected with circoviruses with no apparent consequence.
Explanation: One explanation for viral virulence is that it facilitates transmission. However, a comparison of infections caused by two enteric viruses, poliovirus and norovirus, does not support this general view. Both viruses infect the gastrointestinal tract and are spread efficiently among humans by fecal contamination.
Deadly particles like SO2 that comes into contact with the air will form air pollution. This deadly particles will then form acid rain. When those rain comes into contact with water supply, they turn the water acidic. They will cause river to be too acidic for fishes and other living organisms to survive.

Explanation:
Tributyrin agar Is the inability of this medium to distinguish between these different enzymes a weakness in its specificity or its sensitivity.
Lipases break down lipids (fats).
Tributyrin oil is a type of lipid called a triglyceride. Other lipase tests use different fat sources such as corn oil, olive oil, peanut oil, egg yolk, and soybean oil.
Lipase allows the organisms that produce it to break down lipids into smaller fragments. Triglycerides are composed of glycerol and three fatty acids. These get broken apart and may be converted into a variety of end-products that could be used by the cell in energy production or other process.
Tributyrin oil forms an opaque suspension in the agar. When an organism produces lipase and breaks down the tributyrin, a clear halo surrounds the areas where the lipase-producing organism has grown.
Answer:
Chimpanzees are the animals which are the closes to humans. Infact, the genome of chimpanzee is 98.6% similar to the genome of humans. Humans are thought to have evolved from chimpanzees.
Chimpanzees walk on all fours and have longer arms than legs. They are called “knuckle walkers” because they use their knuckles for support. Like humans, chimps have opposable thumbs and opposable big toes which allow them to grip things with their feet. This feature of chimpanzees for using knuckles for support makes them unique.
Chimpanzees are the only kind of animals which have the capability to groom each other which makes them unique.
