Answer:
It helps us to see things.
It helps plants to make food and grow.
It is used in power satellites and space stations.
It is used in many electronic appliances.
The energy of light from the sun can be harvested to solar panels and can be used for domestic use since it is eco-friendly and cost effective too.

Answer:
The diameter of the xylem vessels should be small in order for the capillary action to take place.
Explanation:
The vessels through which water is transported to different parts of the plants and trees are the xylem. Water is transported in the trees through a mechanism named as capillary action. This mechanism can occur only if the diameter of the vessels are small.
The water molecules adhere to the walls of xylem and an upward force is generated. If the diameter of the vessels i.e xylem would be small then the surface tension between the xylem and water molecules would be enough to move the water in an upward direction.
This is because twilight or mesopelagic zone (extending from 200 meters to 1,000 meters) is the zone that contains the thermocline.
A thermocline or the thermal layer is a layer in an ocean or lake where the temperature changes more rapidly with depth than in the other layers. The thermocline in twilight zone divides the upper mixed layer from the calm deep water below.
Answer:
The best answer to the question, given the research found on this particular process in E. Coli specifically, would be: D) It identifies hemimethylated base pairs and methylates the unmodified base.
Explanation:
According to research on this pretty complicated topic, in E. Coli specifically, and other gram negative prokaryotes, it has been found that the presence, or absence of methylation will initiate MutS, which is a protein both in prokaryotes and eukaryotes responsible, in a full complex, of initiating and carrying out the full mechanism of DNA mismatch repair. As the daughter DNA strands are produced from parent strands, these first ones arise with several deletions and mismatches which need to be repaired and they are recognized due to the fact that daughter strands are hemimethylated. This circumstance activates MutS in E. Coli, who will then bind to the DNA strand that needs to be repaired and together with other members of the complex, like MutH and MutL, begin the process of repair.
In eukaryotes and other prokaryotes, the exact process by which DNA is repaired by MutS is still not totally known.
