Active transport
Hope this helped :)
The answer is a. to determine what sort of data table will be most useful.
Controlled experiment is used parallel with experiment in which some alteration of the subject is induced. This is because this way can be compared in treated and non-treated subject. When sort of data table is necessary, using the controlled experiment, it can be determined what sort of data table will be most <span>useful.</span>
In the first segment that covers the top part of the ocean the whale sharks producers serve as the basis of the food chain. In the top layer of the ocean enough sunlight hits the water which makes it a good place for planktons to grow. These planktons are then eaten by the whale sharks.
Answer:
b. During replication there is both a leading strand and a lagging strand
.
c. Each replication bubble has two replication forks.
Explanation:
Eukaryotic chromosomes have multiple origins of replication to replicate the long chromosomes at a higher rate.
The two DNA strands have opposite polarity, that is, 5' end of the one DNA strand is present opposite to the 3' end of the other DNA strand. DNA replication occurs only in 5' to 3' direction and the direction of the movement of the replication fork is also 5' to 3' direction.
To allow the DNA replication in 5' to 3' direction on both strands, one strand is replicated discontinuously in the direction opposite to the movement of the replication fork.
The discontinuously replicated strand is lagging strand while the other one is the leading strand.
DNA replication in eukaryotes occurs bidirectionally as two replication forks are formed at each replication bubble, one at each end of the replication bubble.
The presence of multiple origins of replication and the bidirectional process allows the replication of large eukaryotic DNA at a considerable fast speed.
