Explanation:
<span>The blood flows through hepatic portal vein traveling to the liver, then makes it another artery which is posterior vena cava making it to the heart. It makes itself afterward to the pulmonary artery where it reaches the lungs, going back to the heart via the pulmonary vein. Eventually, it goes to the kidney through different parts such as the aortic arch, dorsal aorta and the renal artery.</span>
Answer:
The correct answer is e3
Explanation:
The given protein in the question proteib X contain four subunits of equal size alpha,beta,delta and gamma which are bound by either noncovalent interactions or disulfide bridges and only beta and delta subunits are bound to each other by disulfide bridges.
As a result when the protein will undergo fragmentation it will generate 3 bands because the interaction that is present between alpha and beta subunit will break resulting in the formation of 2 bands. Now the most important fact is that the beta subunit is linked to delta subunit by di sulfide bond so when betamarcaptoethanol will act on protein X it will break the disulsulfide bond present between the beta and delta subunit to reduce both the subunit.
Finally the interaction that is present between delta subunit and gamma subunit will be broken down to release the delta subunit which will form a single band during SDS PAGE..
This is what i know:
Flowers usually have more stamen because they need to ensure that there is enough pollen to fertilize the seeds from the
pistil.
