The answer is A
Using energy
Answer:
Explanation below
Explanation:
It should be understood that the population growth rate of a particular country can be explained or described as the increase in the number of the citizens of that country.
There are so many factors that contribute to an increase in the number of people of a country. These include influx of people into the country, increase in birth rate and decrease in death or mortality rate.
In this case, the growth rate is usually calculated in percentage, so the growth rate should be around 3.5%.
Long-term potentiation (LTP) is considered a cellular correlate of learning and memory. The presence of G protein-activated inwardly rectifying K(+) (GIRK) channels near excitatory synapses on dendritic spines suggests their possible involvement in synaptic plasticity. However, whether activity-dependent regulation of channels affects excitatory synaptic plasticity is unknown. In a companion article we have reported activity-dependent regulation of GIRK channel density in cultured hippocampal neurons that requires activity oF receptors (NMDAR) and protein phosphatase-1 (PP1) and takes place within 15 min. In this study, we performed whole-cell recordings of cultured hippocampal neurons and found that NMDAR activation increases basal GIRK current and GIRK channel activation mediated by adenosine A(1) receptors, but not GABA(B) receptors. Given the similar involvement of NMDARs, adenosine receptors, and PP1 in depotentiation of LTP caused by low-frequency stimulation that immediately follows LTP-inducing high-frequency stimulation, we wondered whether NMDAR-induced increase in GIRK channel surface density and current may contribute to the molecular mechanisms underlying this specific depotentiation. Remarkably, GIRK2 null mutation or GIRK channel blockade abolishes depotentiation of LTP, demonstrating that GIRK channels are critical for depotentiation, one form of excitatory synaptic plasticity.

An adaptive mutation is a beneficial mutation that may confer an adaptive advantage to the species.
<h3>What is a mutation?</h3>
A mutation is any modification in the genetic material (DNA sequence) or genome in the cells of an organism.
Mutations can be beneficial, detrimental or neutral according to their position in the genome and the environment in which the organism lives.
In conclusion, an adaptive mutation is a beneficial mutation that may confer an adaptive advantage to the species.

Answer: Neurone
Explanation:
Neurone is also known as nerve cell. It is the basic unit of the nervous system, and helps to transmits/ conducts nerve impulses from the brain to the body or vice versa.
