Answer:
Explanation:
These reactions occur within specialised membrane discs within the chloroplast called thylakoids and involve three steps:
Excitation of photosystems by light energy.
Production of ATP via an electron transport chain.
Reduction of NADP+ and the photolysis of water.
Answer:
<em>The correct option is B) Capillary action, when adhesive forces are stronger than cohesive forces.</em>
Explanation:
When water leaves from the leaves of a plant through events such as transcription, a gap is produced in the capillary action of the xylem tube. As a result, more water is drawn from the roots to fill the void. The forces of attraction between the water and the xylem tube are much greater than the intramolecular forces of water. As a result, the water flows in an upward direction due to these string adhesive forces present between the water and xylem tube.
Answer;
Sister chromatids may drift apart after being synthesized.
Explanation;
-Cohesin is a protein which localizes between the sister chromatids and holds them together to resist the pull of the kinetochore microtubules.
-Because cohesin enables sister chromatids to remain attached from the time they are synthesized during S phase until the end of metaphase. If cohesin is defective, sister chromatids may separate before they normally would in anaphase, which would lead to daughter cells that have too few or too many chromosomes.
