When you get a scratch, the cells in your body will multiply until they reach the cells gathering at the other side of the wound.
What is a wound?A wound is a cut that occurs on the body. When the scratch or the wound occurs, the skin cells that are around that area are destroyed. When this occurs, the person would feel pain as the blood vessels in that area become affected and the individual begins to bleed. The bleeding that the individual experiences is in proportion to the extent of the wound that the individual has.
Having said this, we know that the cells are affected when there is a scratch on the body. The scratch depends on the impact of the object that caused the injury in the body.
Immediately the scratch occurs, the cells that are around the affected area begins to multiply. The multiplication of the cells is in order to cover the area and cause the wound to heal.
Thus, when you get a scratch, the cells in your body will multiply until they reach the cells gathering at the other side of the wound.

2. Explain why a bear will need the following;
a. Food and water
b. Shelter.
c. Mates to reproduce young ones.
Answer:
Competition for food, water, shelter, predation by bears and wolves, and mates would all increase if the population is large and dense.
Explanation:
First of all every living things needs basic food and water to survive.
And without shelter the population would not survive natural disasters and Mother Nature.
They produce young’s ones to keep population steady and not go extinct.
Answer:
A bear is a form of life, and like every form of life, it it has basic needs that have to be met. All organisms need water to survive. Organisms take in food to turn into energy. Without those, the bear would not be able to function and would die. Shelter is needed for protection, essentially. Having a safe place for the bear can shield it from harsh weather, and gives the bear a place to stay safely. If there weren't any mates for the bear, there would not be any way for it to repopulate. The bear will eventually die and there wouldn't be anything to take its place. If this were to happen on a large scale, the bear population would die off, ultimately throwing off the ecosystem and causing a major imbalance in nature.

what has “sprung up” all over phoenix and why is this a problem?
Drought has “sprung up” all over Phoenix.
How Drought has become a problem in Phoenix?About 40 million people in the southwest depend on the Colorado River for their water supply, but it is currently experiencing catastrophically dry conditions. It has been the driest two decades in 1,200 years. Phoenix is one of at least six Arizona cities that have officially declared water shortages. This desert area gets less than 8 inches of rain a year.As Phoenix and its neighbors continue their relentless development — Arizona's population has more than quadrupled in the past 50 years, from 1.8 million in 1970 to 7.2 million today — it has long been debatable how to supply enough water to sustain a city this size in the desert. The potential effects of drought on their daily life, are an increase in wildfires, a decrease in local food, and a decrease in leisure activities because of low lake water levels.How is Phoenix coping up with dry conditions?Phoenix has activated its drought management plan and is asking residents to use less water. The City of Phoenix issued a stage 1 water alert this year. With the alert, individuals are being advised to use less water in ways that won't significantly affect their daily life. One of the simplest and most efficient methods to preserve water, according to the city, is to water landscapes appropriately. The city concentrates on consumer outreach and education about the drought conditions rather than enforcement because the water reductions are voluntary.Phoenix has weathered every drought without having to impose forced water use restrictions or prohibitions thanks to long-term planning, investments in alternate water supply options, and a track record of success with water conservation.To learn more about Phoenix visit:

what is difference between anabolism and catabolism?The body's metabolism is a critical component of growth, development, and effective operation. Based on how they function, it can be divided into two types: catabolism and anabolism. The way molecules are used by the organism in catabolism and anabolism are the main distinctions. Anabolism uses energy to produce the molecules that the body needs to function.

Which term best describes the fine tuning of an antibody mediated immune response, via genetic hypermutatoins?
Adaptive Immunity is the term that describes the fine-tuning of an antibody-mediated immune response, via genetic hypermutations.
Adaptive immunity involves lymphocytes- B cells and T cells which have receptors for any antigen they encounter. When exposed to an antigen, T cells release chemicals to activate B cells. B cells then divide and differentiate into memory cells and plasma cells. Plasma cells produce a large number of antibody molecules to fight against the specific antigens while memory cells reserve some of these antibodies to protect the body from future infections.
Genetic hypermutation changes the affinity of an antibody (B cell receptor) to detect the antigen. This occurs through a process called affinity maturation. It enables an antibody to produce a stronger and specific response to an antigen.
