Answer:
One common neurotransmitter is dopamine. It is an excitatory neurotransmitter that is involved in movement, learning, attention, and emotion. GABA is another common neurotransmitter, and it is a major inhibitory neurotransmitter. It is involved in anxiety, arousal, and sleep. Glutamate is a major excitatory neurotransmitter, and it is involved in learning and memory.
Acetylcholine: Serves as a messenger between each motor neuron and skeletal muscles, which accounts for its role in helping to control skeletal muscles.
Serotonin: Affects sleep, hunger, mood, and arousal; connected to aggression and abnormal behavior
Norepinephrine: Helps control arousal and alertness; helps in regulating mood
Endorphins: Major excitatory neurotransmitter; linked to memory and learning processes; released in response to pain and intense exercise
Explanation:
:) have a good day
Answer:
Dopamine, Acetylcholine, Serotonin
Explanation:
they result in a longer lifespan
they are caused by mutations of the X chromosome
they are linked to an unknown chromosome
they are disorders that affect only women
Answer:
they are caused by mutations of the X chromosome
Explanation:
The X chromosome contains many genes in addition to those that determine sex. Certain hereditary defects determine by recessive genes are linked to the X chromosome. The disorders are caused by mutations of the X chromosomes.

This answer explains the different types of fossils and their descriptions.
The types of fossils and their descriptions are as follows:

B) probably the primitive organism on the left
C) it is certain that the two organisms lived at the same time
D) it is foolish to even speculate about the relative age of the fossils
Answer;
B) probably the primitive organism on the left
Explanation;
The first living organisms we have proof of thanks to fossils, are three and a half billion years old.
Organisms which possess simple body organisation are called primitive organism. They differ from so called advanced organisms as all the activities of life are performed by a single cell.
Primitive organisms do not change their body design so easily as advanced organisms do. Prokaryotes are considered to be primitive forms and eukaryotes are the advanced organisms.
Advanced organisms are complex and have acquired new features morphologically and anatomically by evolution from simpler organisms to better adapt the changing environmental conditions.
B. neap tides.
C. high tides.
D. rip tides.
Water flows toward the hightides, halfway between them causing lowtides. The correct option is A.
They are caused by the moon's and, to a lesser extent, the sun'sgravitationalforces on the earth.
A high tide occurs when the highestpoint of the wave, or the crest, reaches a coast. A low tide occurs when the lowest point, or the trough, reaches a coast.
Water flows toward the hightides halfway between the high tides, causing lowtides. The moon's gravity pulls slightly stronger on the water on the side of Earth closest to the moon than on the entire Earth.
This difference results in a bulge of water on the Earth's side closest to the moon.
Thus, the correct option is A.

Answer:
Neap tides
Explanation:
B. Vacuole
C. Chloroplast
D. Nuclues
Answer:
A. Centriole.
Explanation:
The centriole is the thing at each side of a cell that "pulls" chromosomes apart to the other side of the cell. Here is a photo:
