Answer:
The answer is A.
Explanation:
The bacteriophage is an organism that attacks bacteria and uses them to replicate it's DNA to reproduce and multiply.
If all the amino acids of the bacteria are flagged with fluorescent tag, then the new bacteriophage's DNA will exhibit the fluorescent tag because it will be constructed using the bacteria's protein molecules in the first place. So the answer is A.
I hope this helps.
In an oligopoly type of market, there are only few producers whom dominate the market. This is the market type wherein there are only small number of firms that control the majority of the market share. The opposite to Perfect Competition, wherein there are unlimited number of producers. In an oligopoly, since there are only a few numbers competitors, each firm is likely to be aware of each other's action.
There are all sorts of ways to reconstruct the history of life on Earth. Pinning down when specific events occurred is often tricky, though. For this, biologists depend mainly on dating the rocks in which fossils are found, and by looking at the “molecular clocks” in the DNA of living organisms.
There are problems with each of these methods. The fossil record is like a movie with most of the frames cut out. Because it is so incomplete, it can be difficult to establish exactly when particular evolutionary changes happened.
Modern genetics allows scientists to measure how different species are from each other at a molecular level, and thus to estimate how much time has passed since a single lineage split into different species. Confounding factors rack up for species that are very distantly related, making the earlier dates more uncertain.
These difficulties mean that the dates in the timeline should be taken as approximate. As a general rule, they become more uncertain the further back along the geological timescale we look. Dates that are very uncertain are marked with a question mark.
Answer:
The transport protein-hormone complexes of lipid soluble proteins can not cross the filtration membrane of glomerulus.
Explanation:
Steroid hormones are water-insoluble (hydrophobic) in nature. Since blood has watery medium, the plasma, the lipid-soluble hormones travel in blood through transport proteins. The transport protein-hormone complexes are too large to cross the filtration membrane of glomerulus. The impermeability of the filtration membrane of glomerulus for protein-hormone complexes increases the half-life of lipid-soluble proteins.
