Place the terms into the correct column that describes the reactions of photosynthesis.
Answer:
In the light-dependent reaction, which occurs in the THYLAKOID MEMBRANE of the chloroplast, energy from SUNLIGHT is used to breakdown WATER to release electrons in order to synthesize ATP and NADPH from ADP and NADP+. In a nutshell, the processes involved in this stage are Electron transport chain, photosystem I, photosystem II, and ATP synthase.
- In the light-independent stage, also called CALVIN CYCLE, the ATP, NADPH, and CO2 are used as reactants to synthesize SUGAR (glucose), NADP+ and ADP (which goes back to the first stage) as products.
Explanation:
In the light-dependent reaction, which occurs in the THYLAKOID MEMBRANE of the chloroplast, energy from SUNLIGHT is used to breakdown WATER to release electrons in order to synthesize ATP and NADPH from ADP and NADP+. In a nutshell, the processes involved in this stage are Electron transport chain, photosystem I, photosystem II, and ATP synthase.
- In the light-independent stage, also called CALVIN CYCLE, the ATP, NADPH, and CO2 are used as reactants to synthesize SUGAR (glucose), NADP+ and ADP (which goes back to the first stage) as products.
The light-dependent reactions involve both photosystems I and II along with the electron transport system. ATP is synthesized in this reaction, so ATP synthase is also included.
What is Photosynthesis?Photosynthesis may be defined as a process through which green plants and some photosynthetic algae synthesize their own food in the form of glucose with the help of carbon dioxide and water in the presence of sunlight.
The light-dependent reaction of photosynthesis occurs in the thylakoid membrane. Sunlight and water are the reactants of this reaction. The products of this reaction are NADPH, ATP, and oxygen.
Light-independent reaction involves the Calvin cycle. It occurs in the stromal part of the chloroplast. The reactants of this reaction are carbon dioxide, ATP, and NADPH while the products are glucose, NADP+, and water.
Therefore, the difference between light-dependent reaction and light-independent reaction is well described above.

Explanation:
Adenine (A) and Thymine (T) are base-pairs, alongside Cytosine (C) and Guanine (G). Only A - T or G - C are base-pairs in DNA strands, you will never see Adenine (A) and Cytosine (C) together in a DNA or RNA strand.

Carbon atoms enter the child as part of ________________ . These will first be broken into smaller molecules by _____________. These smaller molecules contain the same ____________ energy. The child needs oxygen so that his cells can perform _______________ __________________ . This process transforms _____________ energy into ____________________ . The carbon atoms leave the child in ________ .
Please help
Answer:
Organic molecules
Digestion
Cellular respiration
CO2
Explanation:
Carbon atoms enter the child as part of organic molecules. These will first be broken into smaller molecules by the process of digestion. These smaller molecules contain the same amount of energy. The child needs oxygen so that his cells can perform cellular respiration. This process transforms chemical energy into energy, carbondioxide gas and water. The carbon atoms leave the body of the child in the form of carbondioxide gas through breathing process..

Under certain external conditions, a person will perspire a great deal. For which internal condition does this response primarily provide homeostasis?
Answer:
Abnormally high temperature
Explanation:
Sweating or perspiration is a homeostatic response to abnormally high body temperature. Evaporation of the sweat causes cooling of the body and this causes the temperature of the body to return back to normal.
When the setpoint temperature of the body is breached by being too high, the negative feedback mechanism kicks-in, and the sweat glands of the skin becomes activated. The body sweats, and the evaporation of the sweat from the surface of the skin causes cooling and a return back to the setpoint.

How does the size of a bacterial cell compare with an animal cell?
Answer:
hope it helped
Explanation:
Bacterial cells are very small - about 10 times smaller than most plant and animal cells. Most bacterial cells range in size from 0.2 to 10 microns or micrometers (0.0000079 to 0.00039 inches). ... One reason why bacterial cells are so small is that they need a large surface area to cell volume to take in nutrients.
All cells in an organism have the same copy of DNA, because they all came from the same orginal cell.
