Which hypothesis most likely explains the results at 60°C and 70°C? O A. The substrate has been used up because of the high temp
erature, O B. The enzyme has changed shape because of the high temperature. O C. The enzyme is only effective at very high temperatures, O D. The bonds in the substrate are weakened at high temperatures
The enzyme has changed shape because of high temperature.
Explanation:
Enzymes are biological catalysts in living organisms that speed up the rate of chemical reactions.
High temperature changes the shape of enzymes.
Increase or high temperature lead to decrease in enzymes activities. This is due to enzyme protein been denatures by high temperature which is the breaking of molecular bonds within the enzyme protein. When the enzymes bonds are broken, the shape of the enzymes changes and they no longer act as catalysts.
To find the allele frequencies, we again look at each individual's genotype, count the number of copies of each allele, and divide by the total number of gene copies
D. Reducing services. This reduces energy spent, and most energy comes from the burning of fossil fuels, which depletes ecosystems and contributes to Global Warming.
