D. The mitochondria of the eukaryotic cells are the sites of cellular respiration and where most of the steps take place. Cellular respiration allows for the release of energy stored in chemical bonds of glucose (obtained from food) to form adenosine triphosphate, which is the energy currency of the cell.
Therapsids are a group of mammal like reptiles that share many features of the body. So basically what this means is that these animals from the Therapsids helps the humans evolve. Therapsids had canine teeth and so do mammals. Their jaws where structured similar to ours and so were their teeth. Their molars were in the back so they chomp their food like meat, just like the humans. The reptiles in the Therapsids group have legs that were more vertical from their body like humans. Where other reptiles did not, they had legs that were sprawled out from their body.The reptiles in the Therapsids group also had turbinates bones like humans. They were also thought to be warm blooded just like humans. There are some similarities that could leave one to believe that there is a connection, but I don’t think so. I think that humans have a more thing in <span>common with chimpanzees</span>
Oxygenic photosynthesis works as a counterbalance to breathing by taking in the carbon dioxide produced by all breathing organisms and reintroducing oxygen to the atmosphere.
The mutation will occur often in offspring and leads to development of genetic variability in the gene pool.
Answer: C
Explanation:
Mutation refers to the process which causes disturbances in the normal DNA pattern.
When such phenomenon occurs over many generations, it will become a common process in offspring and increase the chance of difference in variability in the genetic makeup as well as the gene pool.
It is because, the first stage of mutation appears tedious to the organism.
As it gets transferred from one generation to another generation, the species due to its capability identifies certain ways and exhibit genetic variability due to the mutation.
By this way the mutation will become more common in offspring as their parent have mated in the presence of mutation.
The correct answer is 9 proteins form each of the 20 facets of this virus. A capsid is the protein shell that surrounds a virus. A capsomere is the subunit of the capsid. Depending on the virus, capsomeres arrange in many different shapes to form the capsid. The yellow mottle virus has 20 facets, this means that it has an icosahedral capsid. Since it contains 180 identical capsomeres, we can conclude that 9 proteins form each facet.
