Answer:
Skin serves as a protective barrier, a way to sense the world, and a layer that keeps nutrients and water inside the body.
Explanation:
When it comes into contact with a host cell, a virus can insert its genetic material into its host, literally taking over the host's functions. An infected cell produces more viral protein and genetic material instead of its usual products. Some viruses may remain dormant inside host cells for long periods, causing no obvious change in their host cells (a stage known as the lysogenic phase). But when a dormant virus is stimulated, it enters the lytic phase: new viruses are formed, self-assemble, and burst out of the host cell, killing the cell and going on to infect other cells. The diagram below at right shows a virus that attacks bacteria, known as the lambda bacteriophage, which measures roughly 200 nanometers

Explanation:
1. Describe two effects of insecticide use on the forest ecosystem other than the intended reduction of moths to protect the trees.
1. Insecticides when sprayed on a certain areas or spots can be blown by the wind to other areas or flow with rain water into nearby streams or local water bodies or seep through the soil into ground water. This is called indirect application or secondary poisoning,
2. Insecticides can affect the food chain because they reduce the biomass of primary consumers and there is is less food available to secondary consumers which eat poisoned plants or prey those who have been exposed to pesticides.
Insecticides can travel great distances through the environment and they can also flow with rain water into streams so fish can be directly or indirectly impacted by pesticides. The phenomenon of nutrient enrichment of aquatic bodies is known as eutrophication, which deteriorate the water quality leading to death of fish. Some long-term exposures cause abnormalities or mutations in developing fish larvae, while acute exposure can cause immediate fish die-offs. The liver, kidney, brain and gills of exposed fish are extremely vulnerable to chemical exposure.

The explanation is given in the explanation section.
Explanation:
Osteochondroma is a condition where the cartilage and the bone faces excess growth at the end of the bone near the growth plate. Most often, it strikes the large bones in the leg, the shoulder blade, or in the pelvis. It usually happens between the ages of 10 and 30. It affects males and females equally. The actual cause of Osteochondroma is still not known. There are two types of Osteochondroma. One type that is inherited and one type that is not inherited.
