Explain at least one way in which the quantity and quality of water resources have been affected by human population growth. Predict how you think the water supply will be affected by continued human population growth. Support your response with appropriate evidence and scientific reasoning.
Think of some examples of competition among organisms. What are some things they would need to compete over?
Answer:
Organisms compete for the resources they need to survive- air, water, food, and space. In areas where these are sufficient, organisms live in comfortable co-existence, and in areas where resources are abundant, the ecosystem boasts high species richness (diversity).
Explanation:
Answer:
They would need to compete over space, water, food, resources.

What happens when an organism genome (genetic code) is incorrectly copied or changed?
Answer:
When there is a mistake in the copying of the genetic message that is permanent, a mutation has occurred. Two of the bases in DNA (Cytosine and Thymine) are the most vulnerable, and when this happens, they may pair with each other or themselves and the message is changed.

how does the rock cycle support the explanation that "matter is never created or destroyed?"
Answer:
The chemical elements that make up minerals and rocks are not destroyed. This fact illustrates the principle of conservation of matter. The changes that take place in the rock cycle never destroy or create matter. The elements are just redistributed in other forms.
Explanation:
.

What is the problem with using common names in classification?
A general phobia with unfamiliar latinized scientific nomenclature has proliferated the use of common or trivial names. These names, however, can vary with geographic region, language, or individual preference often and thus, can lead to misidentification or a delay in the proper identification of a toxic plant.
Answer:
The only problem of using common names is that we cannot deduce the features of a particular organism just by looking at its name.
Explanation:
The only problem of utilizing basic names is that we can't find the highlights of a specific organic entity just by seeing its name.
