Answer:
Stratovolcano
Sakurajima, a stratovolcano on the the island of Kyushu, is one of the most active volcanoes on Earth. Since it's first recorded eruption in A.D. 708, Sakurajima has been in nearly constant eruption.
<span>The ventricles are the part of the heart that are responsible for the pumping action to move blood throughout the body. Therefore, the muscles in the ventricles are much larger and thicker to do their job properly. The atrium only has to pump blood through an open valve (the tricuspid valve) into the right ventricle. There is much less resistance to this flow of blood so much less muscle is needed. </span>
The effect of genetically engineered salmon which allows the faster growth rate of the species is that the supply will not be shortened any time soon. However, it may be properly studied if these genetically engineered species are safe for the consumers.

Duplication of an ancestral opsin gene occurred in the primate lineage (Old World primates) and subsequent mutations in the new copy resulted in two types of opsin, instead of just one.
<span>Opsins are a group of light-sensitive proteins found in photoreceptor cells (cone cells) of the retina and they are the primary photopigments in primate eyes. Opsins are involved in vision, mediating the conversion of a photon of light into an electrochemical signal, the first step in the visual transduction cascade.</span>
<span>The difference in colour vision between New and Old World primates results from differing arrangements of the photopigment genes on the X chromosome. <span>In Old World primates the three photopigments are required for trichromatic colour vision and they are encoded by two or more X-chromosome photopigment genes and an autosomal photopigment gene. New World monkeys typically have only one X-chromosome pigment gene</span>.</span>
