Answer:
c.Ionic bond is formed between two metals or two non metals.
<span>DNA stands for deoxyribonucleic
acid. It has a double strand that contains the genes (a hereditary material) of
the organism. It was discovered by James Watson and Francis Crick. Their double-helix
structure was based on x-ray diffraction image named as Photograph 51 or Photo
51. It was taken by Raymond Gosling, a pHD student under the supervision of
Rosalind Franklin. They used this photo to determine the chemical and physical
structure of the DNA and the bond that links the genes altogether. The answer is Rosalind Franklin</span>
The option which would most likely result in the greatest decrease in the rate of a chemical reaction is adding an enzyme inhibitor to a reaction catalyzed by an enzyme.
Enzyme inhibitor is known for slowing down any processes, especially when it comes to chemical reactions, so I'd say A is the correct answer.
Answer:
Blood pressure is cardiac output versus resistance, especially in the capillaries.
Explanation:
When they get atherosclerosis, which is plaque in the arteries, there’s more resistance in the blood vessels and that raises blood pressure
An enzyme is a catalyst which means it changes the speed at which a chemical reaction occurs. It never alters the reaction in any way or changes nay chemical properties, only the speed at which it occurs and is completely absorbed in the meantime. The substrates that are reacting just have their reaction faster.
