<span>Platelets help prevent blood loss at sites of vascular injury. They form a pro coagulant surface and cause a thrombin generation and fibrin formation. In addition, platelet help with tissue repair and influence processes and help with inflammation and the immune response</span>
Answer:
ATP donates energy through C phospho anhydride bond hydrolysis.
Explanation:
ATP or adenosine triphosphate is an energy rich compound which contain 3 phosphate moiety that are linked by 2 high energy phospho anhydride bonds.
The hydrolysis of phosphoanhydride bonds releases high amount of free energy which is used by cellular system of our body to exhibit various cellular,biological and physiological functions.
Some anoxygenic photosynthetic bacteria are able to use H2S or hydrogen sulfide as an electron donor.
Opportunistic pathogens only cause infection under certain circumstances eg in immune compromised hosts.
Hello!
Standards of mass are necessary because it is a whole lot easier than using a bunch of different systems. Since the metric system is common, it would be easier to compare something with someone from America and someone from Germany using the metric system as opposed to something otherwise.<span />
Shunting is blood movement across the chambers of the heart.
Answer:
True.
Explanation:
Yes, the lens of the eye will be more spherical when the ciliary muscles are contracted due to tension. When the relaxation occurs in the ciliary muscle , the zonular tension is increased, that causes the lens to be flatten and leads to decrease in optical power while on the other hand, when the ciliary muscle contracts, the tension in the equatorial zonular is increased which causes the central lens surface to become more rounded that leads to increases central optical power.
