Answer:
The correct answer is c. That is 9 protein to form each facet
Explanation:
Given that the capsids is 25-30nm in diameter and it contains 180 identical capsomeres, if the virus capsid has 20 facets in 180 capsomeres, then for each protein facet, it will contain 9 protein facets.
Thai is 180 capsomeres divided by total number of facets (20).
Answer:
Primary active transport
Explanation:
Primary active transport is the transport in which molecules are moved against their gradient, with direct use of ATP as an energy source. Na/K pump is an example of primary active transport: Na ions are transported out of cell, K ions are moved into the cell. This pumps maintain concentrations of those ions and also creates voltage across the cell membrane, which can be used for the secondary active transport of other molecules (e.g. glucose).
I<span>t is important for Mendel to study such a large sample of pea plants to determine the probability of inheritance because</span> higher sample size gives more accurate results.
>>>Mendel coined the terms “recessive” and “dominant<span>” in reference to certain traits.One best association to this is is his study about pea plants. According to him, green peas are recessive and yellow peas are dominant.</span>
The correct answer should be: Bromide
