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

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 an enzyme immunoassay, the enzyme

antoniya [11.8K]

Answer:

is bound to the constant region of the secondary antibody.

Explanation:

Enzyme immunoassays are the techniques used to detect the presence of antigens with the help of antibodies. Each of the antibody molecules has a constant and variable region.

The primary antibodies are added to the wells. The constant region of the secondary antibody is bound to an enzyme while its variable region is free so that it can bind to the specific antigen.

Addition of substrate to the system is followed by visualization and/or evaluation of antigen as the reaction between enzyme and substrate produce some visible changes such as color change.

In 1958, Meselson and Stahl conducted an experiment to determine which of the three proposed methods of DNA replication was corr

Katen [24]

<h2>Meselson and Stahl conducted an experiment to determine the correct proposed methods of DNA replication was semi-conservative. the three proposed models for DNA replication are semi-conservative, conservative, and dispersive.</h2>

Explanation:

In Semi-conservative replication model, the two strands of DNA uncoil from each other. It perform with the original strand and a new strand.

In Conservative replication model, DNA replication didn't open at all, but the parent strands remains undamaged by creating a new and separate molecule that consists of two new strands.

In Dispersive replication model, DNA replication results in two DNA molecules that consists of both parental and daughter DNA.

He demonstrated that semi-conservative DNA replication is an universal mechanism allocated by all organisms on Earth.

Which statement best describes how carbohydrates help the body maintain homeostasis

steposvetlana [31]

Answer:

they provide the body with energy

Explanation:

Carbohydrates are your body's main source of energy: They help fuel your brain, kidneys, heart muscles, and central nervous system. For instance, fiber is a carbohydrate that aids in digestion, helps you feel full, and keeps blood cholesterol levels in check.
