Answer: The primary motor cortex for control of voluntary muscles is found in the precentral gyrus of the frontal lobes.
Explanations:
The primary motor cortex is one of the important brain areas involved in motor function. It is found in the precentral gyrus of frontal lobes. It control voluntary muscles and generate impulses needed for movement execution.
Voluntary muscles are muscles that we can control consciously or we can control them at will and we can choose when we want to use them. They are also refers to as skeletal muscles and are attached to bones. The are majorly use for locomotion.
Explanation:
Cuando los niveles de testosterona están bajos, la hormona liberadora de gonadotrofina (GnRH) es liberada por el hipotálamo que a su vez estimula la glándula pituitaria para liberar LH. Esta última hormona estimula los testículos para sintetizar la testosterona.
Answer: Although the Moon appears to shine, it does not emit light. Instead, we can see the Moon because it is lit up by the Sun.
Explanation:
The part of the Moon that is both sunlit and facing Earth is called the Moon's phase.
As the Moon orbits Earth, the Moon's phase changes. The model below shows the Moon's phase at eight positions in its orbit. The smaller moons closer to Earth show where sunlight hits the Moon. The larger moons farther from Earth show how the Moon will look during that phase.
Regarding human traits, Locke would most likely agree with Aristotle.
There are more areas where Aristotle and Locke's philosophical views diverge than where they concur. For instance, Aristotle once claimed that a person's happiness was just as important to them as it was to their political community. The political understanding of Locke, however, is different because, in his view, a government only assumes responsibility for a portion of the human rights that it is meant to protect in accordance with what people deem to be right. Individuals are therefore given priority because they have rights that are inalienable and shouldn't be manipulated by people to fit their agenda. These and other traditional philosophies have been used to analyze and comprehend early philosophy.

The correct answer is E. Vertebrates are all related to a common ancestor
Explanation:
According to biology and evolution, organisms from different species but that share similarities in morphology (body structures) as well as in genetics often have a phylogenetic relationship which means they descend from the same organism or share a common ancestor. This applies to multiple taxonomical levels including classes such as mammals or birds as it has been proved each of this derived from a common ancestor. Therefore, the similarity in the body structure (morphology) in all mammals suggest vertebrates are related to a common ancestor and as they evolved from this, they share similarities not only in terms of morphology but also in genetics.
