Answer: D. Heat
Explanation : Water Vapor is a source of warmth, since the heat that is radiated from Earth is absorbed by the water vapor. This is why greenhouses use water vapor as well.
C. Enzymes increase the rate of the chemical reactions carried out during metabolism.
When a human dies, his corpses gets decomposed by decomposing bacteria. What's produced by the decomposing bacteria is the "fertilizer" for plants.
<span>One important area of DNA research is that of genetics and medical research. Due to our discovery of DNA, our ability to actually diagnose diseases early on has been vastly improved. In addition, we have been able to better assess a person's genetic susceptibility to specific diseases. In doing so, we have also paved the pathway to formulate brand new drugs to treat these diseases. In fact, drugs can essentially be custom made to complement a person's personal biochemistry and genetic makeup. For those diseases that were previously considered lethal and where treatment was either non-existent or largely unsuccessful, the discovery of DNA has essentially led to breakthrough drugs and treatments for patients with serious illnesses.</span>
The linear/ sequential search algorithm is not adequate for searching though large arrays
Hope this helps!
