The correct option is D.
Neurotransmitters categorized as inhibitory are expected to hyperpolarize the membrane.
At inhibitory synapses, release of neurotransmitters causes inhibitory postsynaptic potentials or IPSP, which is a hyperpolarization of the presynaptic membrane.
Actually, depolarization and hyperpolarization occurs on neuron when an ion channel in the membrane open or close which can alter the ability of certain types of ions which enter from or exit out of the cell.
Neurotransmitters which is inhibitory have inhibitory effects on the neuron as it means they can decrease the possibility that the neuron will tend to fire an action. Modulatory neurotransmitters can also affect various neurons at the same time which results in the influencing effects of other chemical messengers.
Inhibitory neurotransmitter somehow decreases the action potential of the neuron. When the action potential falls below a certain level which is called threshold potential, the neuron will not be able to generate action potentials and thereby unable to exit the nearest neurons.
So, neurotransmitters are in general expected to hyperpolarize the membrane in some extent.

Answer: C. Ranges and niches are moving farther North
Explanation:
Animals are moving north toward the North Pole to escape the heat. Towards the poles, the temperatures get colder. Because of global warming, the temperature zones move out towards the poles.
Answer:
It looks like there are two main ways to modify humans :)
Explanation:
1. <em>Somatic genetic modification</em> would be the direct way to genetically modify through adding or cutting some of the cells of an existing person usually to alleviate a medical condition (but the results are not hereditary)
<em>2</em><em>.</em><em> </em><em>Germline</em><em> </em><em>genetic</em><em> </em><em>mod</em><em>ification</em> is also a direct way to genetically modify but instead using molecular engineering techniques (this would be hereditary)
Hyponatremia and decreased urine output are exhibited with syndrome of inappropriate secretion of antidiuretic hormone (siadh).
<h3>What is secretion of antidiuretic hormone (siadh)?</h3>
Syndrome of inappropriate secretion of antidiuretic hormone (SIADH) is a condition in which the body produces too much antidiuretic hormone (ADH). This hormone helps the kidneys control the amount of water the body loses through urine. SIADH causes the body to retain excess water. ADH is a substance that is naturally produced in an area of the brain called the hypothalamus. It is then released from the pituitary gland at the base of the brain.
There are many reasons why the body needs to produce large amounts of ADH. Common situations where ADH is (improperly) released into the blood when it shouldn't be produced include:
- During surgery General anesthesia
- Brain disorders such as trauma, infections and stroke
- Brain surgery involving the hypothalamus
- Pulmonary disorders such as tuberculosis, cancer, chronic infections and pneumonia
- Substance abuse
Rare causes include: There is a thing Pituitary
- Leukemia and cancer of the small intestine, pancreas and brain
- Psychiatric disorders
