Answer: Option A.
Cause clot dissolution to proceed faster.
Explanation:
Plasminogen activator is a substance that activates plasminogen to plasmin. Plasminogen activator is a serine proteases which catalyze the activation of plasminogen. The damaged blood tissue releases tissue plasminogen. The plasmin is important to break fibrin polymers that is formed during clotting of the blood. Increased plasminogen levels cause blood clots to dissolve faster.
Answer:
No 15N/15N labeled DNA was observed in second generation
Explanation:
Meselson and Stahl were doing an experiment to find out the semi-conservative mode of replication of DNA. The first cultured bacteria in 15N medium which was containing a heavy isotope of nitrogen. The DNA synthesized here had more density. After that they transferred the bacteria to the 14N containing medium. When bacteria reproduced and new strands of DNA were synthesized, they observed the following -
- The first generation had hybrid DNA with 15N/14N strands
- The second generation had both hybrid 15N/14N DNA and 14N/14N DNA strands
- There was no 15N/15N DNA observed.
In this way they proved that one strand of DNA is kept conserved during the replication.
The correct order is:

Thank you for posting your question. I hope that this answer helped you. Let me know if you need more help.
Since mature red blood cells do not contain a nucleus, more
room is available for hemoglobin. I am hoping that this answer has satisfied
your query about and it will be able to help you, and if you’d like, feel free
to ask another question.
