Explanation:
Precipitation is any form of liquid or solid water particles that fall from the atmosphere and reach the surface of the earth.
Answer:
Precipitation is water that goes through a process that prosses is water evaporates and the turns into clouds then when there is enough water in the clouds it rains and starts over again.

Answer:
The correct answer is B
Explanation:
Transposons need to regulate their copy number to avoid errors with chromosomal pairing during meiosis and mitosis such as unequal crossover.
A typical example of this error is called the Alu Sequence or Elements. Alu elements contain more than one million copies found everywhere in the genome of human beings.
Many inherited human diseases such as cancer are related to Alu insertions.

To minimize their negative impact on a host cell's genome, transposons need to regulate their copy number. Unregulated replication could lead to harmful mutations.
Transposons, also known as jumping genes, are sequences of DNA that can move around to different positions within the genome of a single cell. Their movement can cause mutations, which can have negative impacts on the host cell. In order to limit their negative impact on the host cell's genome, transposons need to B. regulate their copy number. If they did not manage this, over-replication of transposons could overload the cell with unnecessary genetic material, leading to harmful mutations or even cancer.

B. transporting oxygen across the cell membrane.
C. breaking down unneeded molecules.

D. taking in wastes from other cells
The correct answer is D. taking in wastes from other cells.
The correct answer is D. taking in wastes from other cells.
Homeostasis is the process by which cells, organisms, or systems maintain stable internal conditions. To achieve and maintain homeostasis, cells perform various processes such as making new molecules for growth, transporting substances across cell membranes, and breaking down unneeded molecules. However, taking in wastes from other cells does not contribute to maintaining homeostasis and is not a recognized process for this purpose.

B. It is a small pilot study on non-AWAR species.
C. It is a teaching activity that uses students' personally owned dogs and cats.
D. There are no circumstances in which animal work may begin before IACUC approval.
Answer: the correct option is D (There are no circumstances in which animal work may begin before IACUC approval)
Explanation:
The IACUC known as Institutional Animal Care and Use Committees is a local working group that research facilities must appoint in accordance with the Animal Welfare Act , Policy on Human Care and Use of Laboratory Animals. It was introduced to research system by the U.S. government in 1986. The policy protects all warm-blooded animals except rats, mice, and birds bred for research. For an institution to use a specie that is covered by the policy, it must obtain their approval before work begins. I hope this helps. Thanks.
