Salutations!
Organisms that derive their energy from the sun and carbon from carbon dioxide area photoautotrophs. These organisms carry out photosynthesis. Examples of photoautotrophic organisms are: algae, green plants etc.
Hope I helped (:
Have a great day!

Spiders do not have muscles for extending the legs at these joints. Spiders, like most creatures, desiccate upon death, losing their waters, explaining why spider legs curl up upon death.
Answer:
b. brings the postsynaptic cell to the chloride equilibrium potential
Explanation:
Gamma-aminobutyric acid (GABA) is one of the most important neurotransmitters, chemicals that brain cells use to communicate with each other. In fact, it is the most frequent inhibitory neurotransmitter. Inhibiting neurotransmitters decrease the chances that a nerve impulse will be triggered.
The main function of GABA as an inhibitory neurotransmitter is to slow down brain activity. It is also involved in vision, sleep, muscle tone and motor control.
It is widely distributed both inside and outside the central nervous system. It is found in the intestines, stomach, bladder, lungs, liver, skin, spleen, muscles, kidneys, pancreas and reproductive organs.
In vertebrates, GABA leads the postsynaptic cell to the chloride equilibrium potential. Through it, chloride ions flow out of the cell to achieve equilibrium.
