Answer:
b. locate replication sites.
Explanation:
During replication, the function of the enzyme DNA polymerase is to locate replication sites.
Answer:
ATP synthesis by oxidative phosphorylation will stop.
Explanation:
Cyanide inhibits cytochrome oxidase that passes electrons to the molecule oxygen. Cytochrome oxidase also pumps two protons from the matrix to the intermembrane space during electron transfer. Inhibition of cytochrome oxidase would not allow the transfer of electrons to oxygen and the whole electron transport chain would be stopped. There would not be any generation of proton concentration gradient to drive the process of ATP synthesis. Hence, ATP synthesis by oxidative phosphorylation will be stopped after cyanide poisoning in aerobic cells.
Answer: The answer is A: The Inferior Colliculus
Explanation:
The inferior Colliculi play a major role in hearing. Since the loud noise was what prompted the response it is safe to say the inferior Colliculi is responsible.
Neurons in the inferior Colliculi respond to cues such as intensity, the difference red in arrival of sound to both ears.
However, the head snaps up because the information from the inferior Colliculi is transmitted to the superior Colliculi which is involved with movement such as the head.
Answer: A - Uptake of food and water by plants
The xylem vessels in the roots of the plants use the mechanism of capillary action and work against gravity to pull water molecules and nutrients from the soil and carry them upwards to the leaves of the plant to provide nourishment to the plant.
Hi!
The ancestral finch founded a new population on one of the Hawaiian Islands. Due to the founder effect , allele frequencies of the first small population on one of the islands could have differed from their continental goldfinch-like ancestors. The process of natural selection resulted in adaptation and evolution of the island population into a new species over time. Some of the birds crossed to some of the other islands where they were geographically isolated and evolved into more species occupying different niches.
In terms of population genetics, founder effect is when there is a loss of genetic diversity as a result of the establishment of a new population by a relatively few individuals. Following such an establishment, natural selection is the process which results in the genes of the fittest individuals of the population being selected over generations. This process ultimately results in evolution, and over time may give rise to new species. Geographical isolation is the physical separation of a population from another owing to geographical changes in the terrain or area. If two populations of the same species are geographically isolated, there is a great chance over time they may evolve into two different species.
Hope this helps!
