If you change two of the three variables than you don’t know if the change is caused by variable A or variable B. In this case if you keep light constant but change the amount of co2 and the color of the light, you can’t which of these two are affecting photosynthesis.

what is the autonomic nervous system about? explain full details, like a reflection on it. I will give brainliest if answered co
DochEvi [55]
The autonomic nervous system is responsible for regulating the activity of glands, smooth muscle, and cardiac muscle. its under involuntary control, meaning it works without us telling it to do so. it's divided into two divisions: sympathetic and parasympathetic. in sympathetic division, here, the preganglionic fiber is short and the preganglionic fiber is long. sympathetic division is very important during emergancy situationd and is commonly associated with "fight or flight" response. it accelerates the heartbeat, dilates the bronchi, and inhibits the digestive tract. the parasympathetic includes cranial nerves and fibers. it is often referred to as the "rest and digest division". here, the preganglionic fiber is long and the preganglionic fiber is short. it promotes responses associated with a relaxed state, such as pupil contraction, digestion of food, and a reduced heart rate.

hope this helps!!

When an ATP molecule is activated or used, what are the resulting molecules?
Sidana [21]
All living things require energy to function. While different organisms acquire this energy in different ways, they store (and use it) in the same way. In this section, we’ll learn about ATP—the energy of life. ATP is how cells store energy. These storage molecules are produced in the mitochondria, tiny organelles found in eukaryotic cells sometimes called the “powerhouse” of the cell.

Nikolay [14]
<h3><u>Answer;</u></h3>

Distillation

<h3><u>Explanation</u>;</h3>
  • Distillation is a process of separating the component substances from a liquid mixture by selective evaporation and condensation.
  • Distillation is the process of separating components of a mixture based on different boiling points.
  • To separate a mixture of liquids, the liquid can be heated to force components, which have different boiling points, into the gas phase. The gas is then condensed back into liquid form and collected.
  • It is applied in processes such as purification of alcohol, desalination, crude oil refining, and making liquefied gases from air.
