Plants use sunlight to convert nutrients into energy. What form of energy transfer is taking place?

2 answers:

6 0

Plants converts solar energy into chemical energy through the process of photosynthesis . The electron and proton from the water molecules are used to produce energy transport molecules i.e ATP and NADPH, in the light reaction phase of photosynthesis. The energy of the sun excites the chlorophyll molecule which in turn release high energy electron. The energy of ATP and NADPH is further used to fix the carbon in the Kelvin cycle.

Answer: The correct answer is-

Solar energy ( light energy ) to Chemical energy.

Plants synthesize their own food using carbon dioxide and water in the presence of sunlight. This process is called photosynthesis.

During this process, energy from sunlight is first absorbed by chlorophyll ( a green pigment present in the chloroplast) and then it is converted into chemical energy in the form of ATP and NADPH.

In the next phase ( a light independent phase), this chemical energy is then used for the formation of carbohydrate ( glucose).

Thus, light energy is converted to chemical energy during photosynthesis.

In many animals, height is an example of a polygenic trait. Which types of natural selection can affect polygenic traits? I. dir

Marat540 [252]

The question is incomplete as it does not have the options which are:

I. only

I. and II. only

II. and III. only

I, II, and III.

Answer:

I, II, and III.

Explanation:

The mechanism of natural selection can be explained for the trait which is determined by one gene but the traits which can be determined by more than one gene like height (polygenic trait), the selection becomes very complex.

The natural selection can be explained by the phenotype produced in a population and that depends on the genes. The polygenic trait shows the variation in the population, therefore, it is impossible to predict only one mechanism and therefore all types of natural selection occurs on a population.

Thus, I, II, and III are correct.

. As arteries extend outward they decrease in thickness until they turn into microscopic vessels known as_ ((frog dissection))

sveticcg [70]

ANSWER: The correct answer is CAPILLARIES

EXPLANATION: Arteries are the muscular wall tube that carries oxygenated blood from the heart to other part of the body. The arteries extend outward from the heart, and form capillaries.

The capillaries are hairlike thinnest blood vessels, that helps to join the arteries and ventricles together. The blood in the arteries extends to the capillaries of the organs where the blood is supplied, and then moves out to from the organ via the ventricles.

The capillary starts from the part of the arteries that are very thin.

Which of the following occurs after a condon and anticondon form hydrogen bonds<br><br>

xxTIMURxx [149]

Answer:

Anticodon. The anticodon region of a transfer RNA is a sequence of three bases that are complementary to a codon in the messenger RNA. During translation , the bases of the anticodon form complementary base pairs witht the bases of the codon by forming the appropriate hydrogen bonds.
