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.

Two balloons having the same charge of 1.2 × 10-6 coulombs each are kept 5.0 × 10-1 meters apart. What is the magnitude of the r

Pavel [41]

The answer is 5.2 × 10-2 newtons.

To calculate this, we will use Coulomb's Law:
F = $\frac{k * Q_{1} * Q_{2} }{ r^{2} }$
where F is repulcive force, k is constant, Q is charge, r is distance between charges.

If:
 $Q_{1}$ = $Q_{2}$ = 1.2 × $10^{-6}$ C²
r = 5.0 × $10^{-1}$ C²
k = 5.0 × $10^{9}$ $\frac{N*m^{2} }{ C^{2} }$

Then:
 $F = \frac{5.0* 10^{-1} \frac{N* m^{2} }{ C^{2}} * 1.2 * 10^{-6} C * 1.2 * 10^{-6} C }{(5.0* 10^{-1} m)^{2}}$
⇒ $F= \frac{9 * 1.2 * 1.2 * 10^{-3} N }{25* 10^{1} }$
⇒ $F = \frac{12.96* 10^{-2} }{25} N$
⇒ $F = 5.2 N$

As you may have found, population-based patterns can be found in the genotypes of particular genes. We did this exercise on a ha

Nikolay [14]

In diseases, similar patterns of mutations in harmless genes may possibly be a cause or an effect of the disease. To investigate if it is a cause, it is worth looking into the proteins synthesized by the gene and whether it’s structure or functionality is affected by the pattern observed. It is also worth looking into the downstream effects possibly caused by the pattern in the gene. The gene may encode a non coding region which could affect post transcriptional splicing for example.

GuDViN [60]

The fact that the jovians planets have high masses and hence generate powerful gravitational fields, but they have a low average densities indicates about their interiors composed mainly of very light elements, such as H and He. The jovians planets compose of only very light elements like He and H.
