What is microgravity, and what causes it?
fgiga [73]

Answer:

The answer is because they are in free fall. In a vacuum, gravity causes all objects to fall at the same rate. The mass of the object does not matter. If a person drops a hammer and a feather, air will make the feather fall more slowly. But if there were no air, they would fall at the same acceleration.

n200080 [17]

Answer:

answer should be "making water hypoxic for organisms". reason is because the runoff from these treatment plants are filled with nutrients, which will cause eutrophication. eutrophication is excessive algae sprouts which create more DO but then later becomes all used up when they decompose, making it so other organisms have no oxygen.

Answer:

DNA replication

Explanation:

DNA is the genetic material and serves to store genetic information. The genetic information is transmitted from a parent cell to the daughter cells or from the parent to the progeny by the process of DNA replication.  

DNA replication is the process that occurs in the nucleus in eukaryotes and includes the synthesis of new DNA strands using the existing DNA strands as a template. The newly formed DNA molecules are then distributed among the daughter cells during cell division. Thereby, the process of DNA replication ensures that the DNA of the parent generation is carried to the next generation.

For instance, sperms and egg cells in humans carry the DNA of male and female parents respectively to the young one. DNA replication occurs in sperm mother cells and egg mother cells during the formation of sperms and egg cells respectively.

Answer:

Approximately 6944 glucose residues are added enzymatically per second

Explanation:

Cellulose is the main structural polysaccharides in plants. It is composed of unbranched glucose monomer units linked to each other by beta 1-4 glycosidic bonds.

The cell wall and stem of plants cells are composed of cellulose fibers. They provide rigidity and support to the plant.

In the given bamboo plant, the enzymatic addition of glucose units to the growing cellulose fiber chains results in the phenomenal growth rate of the bamboo stem.

Since each glucose unit contributes ~0.5 nm to the length of a cellulose molecule, number of glucose units required for daily growth is calculated as follows:

0.5 nm = 10⁻⁹

0.3 m/0.5 x 10⁻⁹ m = 600000000 units of glucose per day

Number of seconds in a day = 24 * 60 * 60 = 86400 seconds

Number of glucose residues added per second = 600000000/86400

Number of glucose residues added per second = 6944.4 glucose molecules per second

Therefore, approximately 6944 glucose residues are added per second
