The answer is splitting of water molecules. This happens during the light stage of photosynthesis where light energy from the sun is absorbed by chlorophyll is used to split water molecules into hydrogen ions and oxygen. This process is called photolysis. The hydrogen ions joins the dark stage or the light independent stage, while oxygen gas is either released to the atmosphere or used for cellular respiration.
<span>The 4 categories of macromolecules include carbohydrates, proteins, lipids, and nucleic acids. Carbohydrates (grains and vegetables) are the largest group at the base of the pyramid, proteins (milk, poultry, eggs, nuts) follow up the pyramid while lipids (fats and oils) are the least amount at the summit of the pyramid. </span>

</span><span>The aim of the pyramid is to recommend ideal rations for a healthy diet. Carbohydrates provide most of the energy needs for the days’ activities hence taking the largest portion. Proteins are used in building muscles, f0r nutrition, and body’s immunity hence required in lesser amounts compared to carbohydrates. Lipids help the body store energy since they have thrice as much energy as carbohydrates.They also a constituent of cell membranes and also help deliver vitamins. They are required in the least amount to avoid obesity and related illnesses such as cardiovascular <span>diseases</span></span>
Answer:
The amount of electricity a hydropower plant produces depends on two factors: How Far the Water Falls. The farther the water falls, the more power it has. Generally, the distance that the water falls depends on the size of the dam.
Explanation:
Because it can be a matter of our physical safety. In the wilderness a loud noise nearby is usually not a good thing. It is just natural instinct for the majority, if not all, species.

Explanation:
STD is an acronym for sexually transmitted disease and it can be defined as diseases that are easily transmissible or contractable from another person through sexual intercourse. Thus, STD spread from an infected person to an uninfected person while engaging in unprotected sexual intercourse. Some examples of STDs are gonorrhea, chlamydia, syphilis, HIV, etc.
HIV is an acronym for human immunodeficiency virus and it refers to a type of disease that destabilizes or destroy the immune system of a person, thus, making it impossible for antigens to effectively fight pathogens.
Generally, contracting STDs has a detrimental effect to a patient because it causes an opening (break) or sore in the body of the carrier (patient) and as such making them vulnerable to diseases that are spread through bodily fluids e.g human immunodeficiency virus (HIV), Hepatitis, staphylococcus, AIDS, etc.
Hebce, having a sexually transmitted disease (STD) increases your risk of contracting HIV.
