In humans, identical twins are possible because C. early blastomeres can form a complete embryo if isolated.
Identical twins are formed when an egg after fertilization by a sperm gets divided into two.
The early blastomeres are totipotent cells which means that they have the capability to form all the cells of the body further. Hence, if an egg after fertilization splits into two, it has the potential to form a complete embryo which forms an individual.
However, as the splitting process has occurred after fertilization, hence the two individuals formed will be identical twins. The genome for the identical embryos will be identical.
Identical twins are also referred to as monozygotic twins as they arise from a single egg or zygote.

Answer:
this placement increases the chances of pollination
Explanation:
Pollination refers to the process of transferring pollen grains from the male stamens of a flower to the female stigma. The stamens generally surround the pistil and they are composed of two structures: 1-the anther (produces male reproductive cells or pollen grains) and 2-filaments (supports the anthers). Moreover, the female pistil is generally located at the center of the flower and it is composed of three structures: stigma (a sticky bulb in the center of flower), ovary (contains female reproductive cells or ovules), style (supports the stigma). The arrangement of the plant's reproductive organs increases the chances of pollination: when a pollinator (e.g. bees) visits a stigma for nectar it has to go through the stamen and catch pollen that then carries to the stigma of the same flower (auto-pollination) or another flower (cross-pollination). Moreover, the flowers also have petals and sepals that help attract pollinators and protect the flower bud, respectively.

Las plantas terrestres o embriófitas son aquellas capaces de crecer y desarrollarse sobre la tierra. Son un clado o grupo monofilético descendiente de algas verdes y otras especies acuáticas, pero adaptado a la vida fuera del agua. Algunas embriófitas pueden ser semiacuáticas.

One major function of a monosaccharide<span> is its use for energy within a living organism. Glucose is a commonly known carbohydrate that is metabolized within cells to create fuel. In the presence of oxygen, glucose breaks down into carbon dioxide and water, and energy is released as a byproduct.</span>
