IPSPs are the result of: a. decreasing membrane conductance to potassium neurotransmitter b. binding to ligand-gated ion channel
bearhunter [10]

IPSPs are the result of:

a. decreasing membrane conductance to sodium

b. decreasing membrane conductance to potassium

c. inhibitory neurotransmitter entering the postsynaptic cell

d. neurotransmitter binding to ligand-gated ion channels that are chloride selective

Answer:

d. neurotransmitter binding to ligand-gated ion channels that are chloride selective

Explanation:

IPSP refers to inhibitory postsynaptic potential (IPSP). It occurs when the neurotransmitters released from the axon terminals of the presynaptic neurons bind to and open the chloride ion channels. This allows the entry of chloride ions into the neuron making the inside of the membrane even more negative. This does not allow firing of the action potential. The postsynaptic neuron is said to be hyperpolarized. Therefore, IPSP results from hyperpolarization of postsynaptic neurons by the opening of ion channels such as chloride channels.

marta [7]

Answer:

B.) is the process of taking materials into the cell

Explanation:

A.) is incorrect because endocytosis move things into the cell by collapsing the cellular membrane around the substance and then budding off.

C.) is incorrect because the material is not always directed to the endoplasmic reticulum. Most the the material is directed to the lysosomes.

D.) is incorrect because phagosomes are created during phagocytosis, a special type of endocytosis.

Pair-bonding in a population of prairie voles can be prevented by .
Ksju [112]

Pair-bonding in a population of prairie voles can be prevented by . B) administering a drug that inhibits the brain receptor for vasopressin in the central nervous system (CNS) of males

<h3>what is pair bonding?</h3>

Pair bonding is an evolutionary feature that may be important for reproduction as well as individual and species survival.

The proximate processes underlying many types of good social behaviours, such as pair bonding and maternal-infant behaviour, are shared by brain and endocrine systems.

The brain systems that rely on peptides, such as oxytocin, vasopressin, opioids, CRH, and associated hormones, are at the heart of pair bonding.

Neuropeptides also help to integrate the autonomic and endocrine effects of pleasant social encounters with behavioural states that promote social bond creation and maintenance.

Explain in detail how high blood sugar and high blood pressure demonstrate a positive feedback loop.
Inga [223]

Platelet aggregation and accumulation in response to injury is an example of positive feedback. Negative feedback brings a system back to its level of normal functioning. Adjustments of blood pressure, metabolism, and body temperature are all negative feedback.

The control of blood sugar (glucose) by insulin is a good example of a negative feedback mechanism. When blood sugar rises, receptors in the body sense a change. In turn, the control center (pancreas) secretes insulin into the blood effectively lowering blood sugar levels.

Examples of processes that utilize negative feedback loops include homeostatic systems, such as: Thermoregulation (if body temperature changes, mechanisms are induced to restore normal levels) Blood sugar regulation (insulin lowers blood glucose when levels are high ; glucagon raises blood glucose when levels are low)
