The ribosomes are a large complex of RNA and protein molecules. They consist of two subunits, and act as an assembly line where RNA from the nucleus is used to synthesize proteins from amino acids.
Answer: C) The benthic invertebrates would decrease in population size because they are eaten by the sea ducks and the phytoplankton would increase in population size.
Explanation:
The benthic invertebrates are eaten by sea ducks. Sea ducks are eaten by bald eagles. If the bald eagle was removed, there would be more sea ducks because they will have no more predators. Since there are more sea ducks, they will need to eat more food, like benthic invertebrates. The benthic invertebrates would have a lower population because the sea ducks eat more of them.
Why not the other answers:
A) The bivalves would not increase in population size. Without the bald eagle preying on sea ducks, there would be more sea ducks, who need to eat more food, such as eating more bivalves.
The phytoplankton would not decrease. With sea ducks eating more food, more benthic invertebrates are eaten. There would be less benthic invertebrates to eat phytoplankton.
B) Tundra swans were never eaten by bald eagles. There is no arrow connecting them.
D) Wading birds were never eaten by ospreys. There is no arrow connecting them.
Explanation:
Answer: Norovirus
Explanation:
Norovirus is the leading cause of food borne illness in the United states. It causes more than 58% of the food borne illness.
It can occur at any time during the whole year. More than 50% of the illness is caused by the new strains of this virus.
This data is given by Center for disease control and prevention that it has the highest number of cases.
The common symptoms are vomiting, inflammation in stomach, diarrhea, et cetera.
Answer:
RNA (tRNA) molecules carry amino acids to the ribosomes during protein .
