DNA is made up of a double helix of two complementary strands. During replication, these strands are separated. ... Most prominently, DNA polymerase synthesizes the new strands by adding nucleotides that complement each (template) strand. DNA replication occurs during the S-stage of interphase.

You observe two populations of chimpanzees using sticks to dig termites out from nests for food. One population uses long sticks
icang [17]

Answer: B. The population using long sticks has mostly long sticks in its environment

Explanation:

Going back to the statement that reiterates the hypothesis after observations about the apes in the Introduction.

Reviewing the findings in this case, on the behavior of using sticks to dig seem to be the focus the experiment and choice length of the stick.

Making a judgment about whether or not the two finding has been supported is next step.

If there are equal numbers of short and long sticks in the environment of each population and the apes chooses one specific we can say their behavior is learned.

 If the chimpanzees using short sticks have made the the sticks short by breaking long sticks then we can say this behavior is learned.

When the Young chimpanzees in both populations start out using sticks of many different sizes we can see that these variables of learning is yet to be perfected.

When individuals in the population that don’t use the common stick length for that population catch fewer termites this reveals a randomness in the behavior of interest.

At this point we can say that if the population using long sticks has mostly long sticks in its environment then there is a biased objective in the study and this does not support the hypothesis that the choice of stick length is a learned behavior.

Vadim26 [7]

Answer:

Loss of cell plate formation and production of multinuclear monads.

Explanation:

The inhibition of cell-plate formation during cytokinesis will inhibit the development of the phragmoplast which function as a scaffold for cell plate assembly  and this will not allow for the formation of a new cell wall needed to separate the two new daughter cells leading to loss of cell plate formation and giving rise to multinuclear monads.

omeli [17]

Answer:

Incomplete dominance

Explanation:

Incomplete dominance is a condition observed in the organisms while studying their genetics.

When the organisms with two alleles for the same trait are crossed, then neither of the two alleles completely express themselves but a new variation of the trait is formed.

This can be observed in the given scenario also when the ed and white flowers are crossed, then the pink flowers (a new variation of the trait) is formed called blended trait.

Thus, incomplete dominance is correct.
