Answer:

C. A-T rich; initiator

Explanation:

Replication origins have A-T rich DNA sequences that attract initiator proteins.

Replication origin is the DNA sequence where replication is initiated in a genome. The replication origin sequences is rich in adenine (A) and thymine (T) bases because it is easier to break the bonds between the bases compared to the bonds between guanine and cytosine. adenine (A) and thymine (T) bases have two bonds joining them as against three bonds between guanine and cytosine

The initiator proteins recognizes  DNA sequences in the replication origin and helps to initiate DNA replication.

Why is it important that a drop of condensate be suspended from the thermometer during a distillation?
MissTica

Distillation is the process of separation in which the volatile parts of a liquid mixture are separated by selective boiling and condensation. This process may lead to partial separation or complete separation. Distillation is employed for a considerable number of commercial processes such as the production of alcohol, kerosene gasoline, etc. During a distillation, it is important that a drop of condensate be suspended from the thermometer because it allows steady distillation and a stable temperature.

Which of four factors that affect evolution apply to the finches that the Grants studied?
harkovskaia [24]

Answer:

The Grants have focused their research on the medium ground finch, Geospiza fortis, on the small island of Daphne Major. Daphne Major serves as an ideal site for research because the finches have few predators or competitors. (The only other finch on the island is the cactus finch.) The major factor influencing survival of the medium ground finch is the weather, and thus the availability of food. The medium ground finch has a stubby beak and eats mostly seeds. Medium ground finches are variable in size and shape, which makes them a good subject for a study of evolution.
