Answers
Answer:
Nondisjunction is the failure of homologous chromosomes or sister chromatids to separate properly during cell division (mitosis/meiosis).

Nondisjunction results in daughter cells with abnormal chromosome numbers (aneuploidy).

What is the relationship between the curve seen in the graph and the environmental health of the oceans?
An increased population will result in the improved environmental health of the oceans due to more scientists inventing better technologies.
An increased human population size means that the ocean's resources will be used more efficiently.
As the population goes up, the oceans are more likely to be used as a habitat for humans.
As the population increases, more demands are put on the ocean to support human life.
Answers
Answer:
As the population increases, more demands are put on the ocean to support human life.
Explanation:
Many countries rely on the ocean for transport and as food sources. Over fishing has continuously been a growing problem as more and more fish are required to sustain populations as well as support more gourmet markets. A higher population will also lead to higher trade rates as more materials that aren't available in one country will need to be imported from others.

Answers
It is important that blood flow varies throughout different organs because of differences in the metabolic activities of the different organs.
What is the circulatory system?The circulatory system refers to the system of organs and tissues which are involved in the circulation of blood around the body.
The circulatory system performs the essential function of delivering nutrients to tissues and cells as well as removing metabolic waste from them.
Since the different organs in the body perform specialized functions, some organs are actively involved in metabolic activities, therefore need greater blood flow.
Therefore, blood flow varies throughout different organs because of differences in their metabolic activities.
