Answer: Option A
The primary function of DNA polymerase is to add nucleotides to the growing daughter strands.
Explanation:
DNA polymerase is an enzyme that synthesis DNA and its main function is to make DNA from nucleotides which is the building block of DNA. It is essential for DNA replication and work in pairs by creating identical DNA strands from the original DNA molecule. DNA copies are created by pairing the nucleotides to each bases present in the DNA molecule.The bases are thymine, cytostine,guanine, and adenine, the pairing occur with any of the above combinations forming two pairs respectively.
Answer:
Hypertonic
Explanation:
In hyper-tonic solutions, the cell will shrink and crenate. The mass and volume of a gummy bear that is placed in a salt solution will decrease due to the effect of osmosis. When placed in water, a hypo-tonic solution, the gummy bear will expand in size and volume due to the water entering it.
The correct answer is option A, that is, placer deposits.
The concentration of heavy deposits known as the placer deposits are produced by the gravitational action, generally found in streams. The minerals that take place as placer deposits comprise copper, gold, magnetite, cassiterite, and copper.
The formation of placer deposits takes place when the metal-bearing rock on land is weathered and the generated debris is washed down to the sea by the rivers. Further by the action of waves, currents, and rides the particles of heavy metal gets amassed to produce mineral sand deposits. These generally occur as beach deposits.
