The answer is similar ecological opportunities on different continents have produced some striking examples of convergent evolution.
When the Pangea continent broke apart, different continents bore varying climates hence species adapted to their environment. Convergent evolution occurred when different species gained similar anatomical features that are resourceful in the environment (continent) in which they are living. An example of convergent evolution is exhibited in bats that are mammals but have features analogous to those of birds such as wings.
Magnification is defined as a measure of the ability of a lens or other optical device to magnify a certain image. The ability of a lens to measure size of an object and magnifies to a certain level is the known as a magnification of a lens.
The formula to measure the magnification power of a certain lens is the product of the objective and ocular lens magnification. For example, when using the lower power lens the total magnification is: 10X ocular x10X low power objective = 100X).
Answer: DNA Ligase
Explanation:
During DNA replication, both the parental DNA strands are separated and act as templates for the synthesis of new strands. The formation of the new strands occurs in only 5'-3' direction and thus both the strands are synthesized in a different manner. One new strand with the template of 3'-5' direction will be synthesized continuously and is called a leading strand. The other strand with the template of 5'-3' direction will be synthesized discontinuously in the form of DNA fragments. These fragments are called Okazaki fragments and the strand is called a lagging strand. DNA ligase connects these fragments later to form a continuous lagging strand.
Therefore, DNA ligase is required for ligation of Okazaki fragments, and in absence of DNA ligase, the ligation of fragments will not occur and the newly synthesized strand will be discontinuous. However, if DNA ligase is not present in the reaction mixture, then the chances are that not all the newly synthesized DNA strands will be discontinuous. Only the DNA molecule with the lagging strand will be in the form of fragments.
I think the correct answer from the choices listed above is option A.
The first type of cell to differentiate is a neuron. The neurons are
cells that process and transmits information through electrical and
chemical signals. Hope this answers the question.
