Select the most accurate statement describing the basic function of the light reactions of photosynthesis. Select the most accur
S_A_V [24]

Answer:

The basic function of the light reactions of photosynthesis is the conversion of solar energy to chemical energy.

Explanation:

In photosynthesis, the light energy is captured by chlorophyll pigment which is present in the thylakoid membrane. Then this light energy is used split water which releases the electron that enters the electron transport chain. Then electrons move through several electron carriers and helps to generates NADPH and ATP.  

These NADPH and ATP are used in the Calvin cycle to fix the carbon into carbohydrates like glucose. Glucose molecules is then used by the plant to get energy source and to make structural components like cell wall. Therefore during photosynthesis solar energy is converted into chemical energy like glucose.

What is the role of RNA polymerase?
LUCKY_DIMON [66]
I think the answer MIGHT be D. RNA synthesis is carried out by proteins known as RNA polymerases that transcribe the genetic information from DNA in a highly-regulated, multi-stage process. But transcribe and translate are different so I'm not a 100% sure. Hope this helps!

Sketch and label a food-web that includes at least 6 different items. Make
astra-53 [7]

Answer and Explanation:

Example of a food-web:

(1) Algae --> (2) Protozoas --> (3) Krill --> (4) Cephallopods --> (5) Medium sized dolphin --> (6) Large Dolphin

The trophic web is the process of energy transference through a series of organisms, in which every organism feeds on the preceding one and becomes food for the next one.

1) The first link is an autotroph organism or producer, such as a vegetable, that can synthesize organic matter from inorganic matter. In this example, the autotroph organisms are algae, that make use of sunlight and inorganic matter.

The next links are the consumers:

2) Herbivores are primary consumers and feed on producers. In this example, herbivore organisms are protozoan.

3) Krills are the secondary consumers and feed on protozoans.

4) Some species of cephalopods feed on krill, among other species.

5) Specialized Cetaceans such as the Risso´s dolphin, feed especially on cephalopods, as they lack upper teeth and they only have a few teeth in their jaws.

6) The killer whale is a big sized-dolphin and a very important predator. It feeds on many animals, and one of them is the Risso´s dolphin.
