Answer:
A. Gram positive bacteria
Explanation:
Gram-positive bacteria have the cell wall that consists of a single thick layer of peptidoglycan. This peptidoglycan layer is 20-80 nm thick in Gram-positive bacteria. On the other hand, the peptidoglycan layer in cell walls of Gram-negative bacteria is only 2-7 nm thick.
The thicker peptidoglycan layer of Gram-positive bacterial cells makes them more resistant to osmotic stress than the Gram-negative cells.
It is always working.
It even works while the person is sleeping to push saliva down the throat.
There was less of it, making it more possible for the species to be extinct.
Answer:
Blood carries carbon dioxide back to our heart and lungs, oxygen back to heart and out to the body
Explanation:
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.
