Dendrites act as an antenna for conducting signals towards the axon of the neuron.
Neurons are also referred to as nerve cells. Parts of neurons are the axon, dendrites, cell body, cell membrane, synaptic knobs, and myelin sheath. Dendrites act as an antenna for conducting the signals toward the axon of the neuron. Dendrites are fibrous branch-like projects. New neurons are formed by the process called neurogenesis. There are a total of 86 billion neurons in our body.
There are two types of nerve cells- motor neurons and sensory neurons. Sensory neurons are also known as afferent neurons. They carry signals from the rest of the body to the control central brain or spinal cord. Motor neurons are also known as efferent neurons. They carry signals from the brain to the effect part.

If the dna triplets is atg-cgt, the trna anticodons are Uac-gca.
<h3>Are codons triplets of tRNA?</h3>
The triplet of bases that is complementary to a codon is called an anti-codon the triplet in the mRNA is called the codon and the triplet in the tRNA is called the anti-codon.
Thus, option "D" is correct.

Answer:
Biogeographic isolation causes changes in gene pools that result from populations being separated.
Explanation:
Biogeographical isolation consists in the separation of a population by a geographical barrier, giving rise to <u>subpopulations</u>.
With isolation, the subpopulations start to suffer different pressures from the environment and consequently the selected genes in one subpopulation will be different from the other subpopulation.
Due to the biogeographic isolation, the two subpopulations will be prevented from crossing and the differences between them will become more and more accentuated, and with that the <u>subspecies</u> appear.
Over time, these subspecies may become so different from each other that reproduction between them becomes impossible.
When this happens, reproductive isolation occurs and, consequently, the emergence of new species. When speciation occurs due to geographic isolation, it is called allopatric speciation.

How the climatic zones of the planet influence rhythmic and seasonal changes
Explanation:
The Earth is tilted 23.5 degrees on its axis, which affects the distribution of the sun’s energy across the surface of the planet. As the Earth orbits the sun every 365 ¼ days, the axis is always pointing in the same direction into space, with the North Pole toward Polaris, the North Star. Around June 22, the northern hemisphere is angled towards the sun, and receives the most direct radiation and the most energy. This is the start of astronomical summer in the northern hemisphere and winter in the southern hemisphere.
