Answer: Chlorophyll
Explanation:
Chlorophyll is the photosynthetic pigment found in the chloroplasts of green plants. It helps the plants to trap solar energy radiated from the sun during day light. This energy trapping by chlorophyll occurs during the Light-dependent stage (first stage) of photosynthesis, followed by Light-independent stage (second stage)
Answer:
A cell that has duplicated chromosome cannot be in<u> G1 phase.</u>
Explanation:
- G1, G2 and S phase are the divisions of the interphase i.e. the resting phase of the cell cycle.
- A cell cycle has two phases; interphase and M-phase.
- During interphase the cell grows and in M-phase it divides.
- G1 is the Gap between the M-phase and the S-phase.
- G2 is the gap between the S phase and M phase.
- DNA replication is confined to the S part of interphase.
- Since G1 phase comes before the S phase , we can say that a cell that has duplicated chromosome cannot be in G1 phase.
The FDA requires retention of investigational drug study records for The answer is C. At least two years after the investigational drug's approval by the FDA
An investigator shall retain records needed to be preserved under this part for a period of two years following the date a marketing operation is approved for the drug for the explanation for which it is being investigated
Iceberg: The formation of icebergs increases salinity because it is taking liquid water out of the ocean without taking the salt.
Sea Ice: Same as icebergs, this increases salinity because it removes liquid water.
Runoff: This decreases salinity because it is introducing fresh water into the ocean, reducing the salt to water ratio.
Evaporation: This would increase salinity because it is removing liquid water from the ocean, increasing the salt to water ratio.
