Answer:

Dopamine.

Explanation:

Schizophrenia is a mental illness characterized by psychotic episodes and the inability to relate thoughts, feelings and actions, accompanied by delusions, hallucinations (auditory, visual, olfactory and tactile), incoherent thoughts, memory disorders and, in occasions, confusion. Dopamine is a hormone synthesized by the brain that acts as a neurotransmitter and allows the connection between neurons. Studies suggest that some of these alterations in mental functions are caused by an excess in the activity of dopaminergic synapses, that is, there is a hyperactivity in those connections where dopamine is produced and expelled, which range from the ventral tegmental area to the nucleus accumbens and the amygdala, which are the main ones responsible for synthesizing and expelling dopamine from brain reward systems.

Lipids and proteins.

Lipids are macromolecules which provide insulation
. 
A macromolecule is a large molecule. There are four groups of macromolecules: carbohydrates, proteins, nucleic acids and lipids. Lipids consist of glycerol and fatty acids and are constructed from fats, oils, waxes, phospholipids and steroids. A lipid's function is to insulate the body and provide warmth in cold conditions. It can be concluded that a person with very little body fat gets very cold easily and a person with a lot of body fat gets very warm very quickly.

Proteins are biological macromolecule and mostly composed of enzymes.<span> Proteins play a role in the physical make-up of a cell or acts as a cytoskeleton –maintains cell shape and figure. These proteins plays different roles and works with nucleic acids and other macromolecules in the cells including cell cycle, cell adhesion, immune response and cell indicators. <span> </span></span>

What are some examples of genetic diversity
Lena [83]

Explanation:

Woody plants, such as trees, tend to have more genetic diversity, on the whole, than vascular plants, such as grasses. Part of the diversity is due to the size of each species' geographic range and how far they can move their genetic information, for example through wind pollination or animal seed dispersers

When an athlete eats more protein or amino acids than he or she needs, the extra amino acids are?
Rzqust [24]

When an athlete eats more protein or amino acids than he or she needs, the extra amino acids are either used in building the muscle tissues or are used in energy expenditure.

Proteins are the macromolecules composed of amino acid as polymers. Protein is an essential food component because it helps in the synthesis and repair of body parts, it help in growth and development, and also provides fuel to the body.

Muscle tissues are the ones responsible for the movement of the complete body. The tissues are rich in blood supply. They are of three categories: skeletal, cardiac and smooth. Any movement in body is possible only because of the contractions and relaxations of muscles.
