Synapse that increases in effectiveness because of simultaneous activity in the presynaptic and postsynaptic neurons is called Hebbian Synapse.
<h3>What is Synapse?</h3>
A synapse is a component of the nervous system that enables a neuron (or nerve cell) to transmit an electrical or chemical signal to an additional neuron or to the target effector cell.
The transfer of nerve impulses from one neuron to another requires synapses.
The synapse contributes to the development of memory. Because of the signaling mechanisms of the receptors, which are activated by neurotransmitters across the synaptic cleft, the connection between the two neurons is strengthened when both neurons are engaged at the same time. The capacity of two interconnected brain circuits is thought to influence how well memories are stored. Long-term potentiation is the name for this process of synapse strengthening.

avascularity is the option term which best explain why nutrient for epithelial cell are obtained by diffusion from the underling connective tissue. Epithelial membrane consist of continuous sheet of cell. one or more layer thick and are attached to the underlying connective tissue by a basement membrane. Nutrient and oxygen reach epithelial membrane by diffusion from blood vessel which are located in the connective tissue beneath the basemen membrane
Answer:
A)100mL B)50mL C)The second option D)Hypoosmotic Environment
Explanation:
The average Na concentration in the seas and oceans of the world is around 3,5% which mean that in 100 ml of sea water, there is around 3,5 grams of Na.
The weight of one mol of NaCl is 58,44 grams. For 3,5 grams of NaCl, we get 3,5/58,44 = 0,060 mol of NaCl which is 0,060x1000 = 60 mmol/100ml. According to this and the information given in the question about the secretion of the salt glands', if the average sodium concentration is 600mmol/L, we have 60*10 = 600mmol/L so it would take 100 mililiters of water to excrete.
If the average Na concentration of the salt gland's secretion were 300 mmol/L, only 50 mililiters of water would be needed to excrete the same sodium load.
The second option of secretion is hyperosmotic to seawater because the concentration is higher.
Osmoregulation is the process of balancing the amount of water and salt between the body of the organism and its surrounding environment. For salt glands to be advantageous for osmoregulation, they need to be in a hypoosmotic environment.
I hope this answer helps.
