Graph attached
Answer:
b. Less energy is needed to start reaction B.
Explanation:
The graph shows two different reactions and the energy required over time
a. More energy is released by the original reaction. - this is false, more energy is required for the original reaction to proceed
b. Less energy is needed to start reaction B. - this is true, the peak of the curve is lower showing less energy is required
c. The original reaction is catalyzed. - this is false, likely reaction B is catalyzed
d. Reaction B occurs at a slower rate.- false, they occur at the same rate.
C (thermal energy to mechanical energy)
Answer:
it's saturated
unsaturated fatty acid will have double bonds
Answer:
C. The common ancestors of these owls were geographically isolated, and over time the allele frequencies changed so much they are no longer able to interbreed.
Explanation:
This is an example of allopatric speciation. Allopatric speciation, also called geographical speciation, involves the development of a new species when the ancestral population becomes separated by geographical barriers such as a river or a mountain range. This could also take place when the ancestors of the two species emigrate to another area.
In different geographic locations, the separated ancestors undergo gradual evolutionary changes, ultimately, the the two species become so genetically diverse that they cannot interbreed.
