Clumped, evenly spaced, and random
There are three common patterns of population distribution. These are clumped, uniform or evenly spaced and random. Clumped distribution is the most common type found in nature. The distance between neighboring individual is at a minimum. This is common among organisms that are usually preyed such as in herds or family groups. Evenly spaced distribution maximizes the distances between individuals. There is usually competition for a resource. Penguins are an example of this distribution. Random distribution or unpredictable spacing is the least common among the three. Each individual is independent of the other. They occur in environments that have consistent environmental resources and conditions.
Answer:
b
Explanation:
These cells are different because they use the same set of genes differently.
The correct answer is (c) Small amounts of a mutagen often do not have an effect on health.
The doctor will explain that small amount of mutagen(x-ray) often do not have any severe health issues. Radiologists are trained to use the optimal amount of x-rays required for the procedure and this amount is very less. Properly carrying out the whole procedure minimizes the risk. The amount of radiation used is small and is turned off soon after the procedure is completed. So, small amount of x-ray exposed for a very short period of time is not risky.
During volcanic eruptions, some of those that is emitted by the volcano are water vapors. With the proper conditions, these water vapors then condense. The precipitation of water vapors from volcanic eruption about 3-4 billion years ago became the origin of the seas.
