Answer:
<em>The answer is plant cells they would be the type of cells you would find a permanent. an animal cell would not have that.</em>
Explanation:
<em>The reason plant is the answer is because plant cells contain a cell wall made of cellulose to strengthen the cell. They also have a permanent vacuole which is filled with cell sap to help keep the cell turgid.</em>
<em>The reason why animal cells don't have a permanent is because Animal cells may have more than one vacuole, and they are smaller than a plant cell's. Vacuoles are used to store materials in the cell that may be used by the cell or wastes that must be moved out of the cell.</em>

Answer:
Alpha-1
Explanation:
Adrenergic receptors are the integral proteins present in the postsynaptic plasma membranes. These receptors are activated when the neurotransmitter norepinephrine and the hormones norepinephrine and epinephrine bind to them. The alpha 1 adrenergic receptors are found in the smooth muscle fibers of blood vessels that serve the salivary glands, skin, and kidneys. These receptors are also found in the radial muscle of iris of the eye as well as in the sphincter muscles of the stomach and urinary bladder.
They exert excitatory effect and lead to contraction of smooth muscles of the blood vessels, dilation of pupil, and closure of sphincters of the bladder.
Answer: ionotropic; metabotropic
Explanation:
A receptor can directly open the channel and exerts an ionotropic effect. The ionotropic effect takes place by the help of ionotropic receptors. These receptors are membrane bound receptor proteins which responds by the bonding of the ligand.
Due to ligand binding the channel opens and allows the movement of ions into the cells which helps in either increasing or decreasing the action potential.
The receptors can also bind to the ligand and produce metabotropic effect which means by the second messenger.

Answer:
Summary. Multiple types of evidence support the theory of evolution: Homologous structures provide evidence for common ancestry, while analogous structures show that similar selective pressures can produce similar adaptations (beneficial features).
