Because identical twins begin as a single fertilized egg that then separates, identical twins share 100 percent of genetic makeup.
<h3>IDENTICAL TWINS:</h3>
Identical twins are a type of twins characterized by their phenotypic similarity. They look so much alike that they are almost morphologically indistinguishable.
Their similarity emanates from their genetic content. Identical twins are formed when two sperms fertilize a single egg, which then splits into two.
Since identical twins begin as a single fertilized egg that then separates, this means that they share 100% of their genetic makeup.

Human monoclonal antibody (mAbs) are emerging in the field of cancer therapy and have become an increasing proportion of new drugs that are recently approved. Although there are some methods to obtain antigen-specific mAbs from human B cells, it is generally impossible to directly immunize human beings with antigens of interest. For example, for infectious agents, those approaches are largely restricted. To solve these obstacles, two main approaches have been developed; either by humanizing antigen-specific antibodies from small experimental animals (which is laborious due to the great genetic differences from humans) or rely on the in vitro selection of antigen-specific binders from human antibody repertoires. However, the human mAbs developed by these methods are usually with low affinity.
We are now coming up with a much better idea that is humanizing non-human primates mAbs instead of murine mAbs. Due to the close genetic relationship with humans, immunized NHPs have more potential to be isolated with high affinity antibody to human target than other experimental species, such as mouse, rat and rabbit. In addition, with appropriate method, NHP antibodies are much<span> easier to be humanized</span> without any loss of affinity compared to widely used murine antibodies.

Answer:
Option A, keystone species
Explanation:
Keystone species are responsible for controlling any species from becoming dominant over all other species. The keystone species are found at the top of all the energy pyramids and food chains.
They control the explosion of population of prey and hence regulate the overall ecological diversity.
Some common example of keystone species is as follows –
Bison, prairie dog, large mammalian predators,
Hence, option A is correct
6. C. Concentration of wind and water.
7. B. Potash
8. D. Exploring rock formations for mineralization
9. B. 30%
10. C. A longwall.
