control group: tree left outside in normal conditions
Explanation:
Answer:
Runoff is one of the ways land water finds its way back to the ocean, so it can join the water cycle again.
Usually, all the water that falls to the land gets soaked in the soil. However, during long rainy periods, or in the spring, when snow and ice glaciers start melting, soil gets oversaturated with water, so this excess water start flowing on the earth's surface. Gravity directs this water from higher to lower areas, where it will flow into some valley river. This river will take the runoff water to another river, then to the sea or the ocean.
Now this water can evaporate and start the water cycle once more.
Nucleic acids function is to make up genetic information in living things. There are two types of nucleic acid and they are DNA and RNA. DNA is the basic instructions for living things. It is passed down from parent to offspring and is found in the nucles of the cell
Answer:
Option D, telophase
Explanation:
Telophase is the last stage of mitosis cell division in which the duplicated genetic material gets arranged into two identical daughter cells. In generals, this phase begins once the replicated, paired chromosomes have separated and arranged themselves on two opposite sides, or poles of the cells. After this, nuclear envelope begins to form around the chromosomes. After telophase, the cell undergoes cytokinesis to divide the cytoplasm of the parental cell into two daughter cells.
Hence, option D is correct
