Eliminate
B) Herbivores would be forced to change into carnivores.
C) The flow of energy in the ecosystem would be affected.
D) The exchange of carbon dioxide in the ecosystem would increase"
The correct answer is option C
If the forest cover in an ecosystem is reduced from 50% to 20%. The most likely effect is that the flow of energy in the ecosystem would be affected.The forest means the green plants that are also known as the producers of the ecosystem and they transfer energy to the consumers and the ecological balance is maintained. If there will be less producers then the flow of energy in the ecosystem will be affected.

Answer: An extra cytoplasm enhance survival of a developing oocyte in such a way because cytoplasm serves as a reservoir of lipids, polysaccharide and lipids for the developing embryo.The more the cytoplasm content, more will be the nutrients for the developing embryo. The cytoplasm forms the yolk and provides nourishment to the developing embryo. As we know that the developing embryo requires more nutrition and the main source of nutrition is cytoplasm because the sperm has no reservoir of its own to provide nutrition to embryo.
Thus, an extra cytoplasm enhance the rate of survival of a developing oocyte.
Extra cytoplasm in a developing oocyte supports survival by providing necessary nutrients from fertilization to implantation, and energy for cell divisions transforming a zygote into an embryo. It also contains the mechanism preventing polyspermy, thereby ensuring successful fertilization and further development.
Retaining extra cytoplasm in a developing oocyte boosts its survival chances by supplying the zygote, formed post-fertilization, with essential nutrients needed during the period up to implantation into the uterus. This is crucial as the sperm solely contributes DNA and not cytoplasm at fertilization. Accordingly, the cytoplasm and all of the cytoplasmic organelles in the developing embryo, including mitochondria, are maternally sourced. Mitochondrial DNA is maternally inherited and critical for tracing biological lineage.
Upon fertilization, the larger amount of cytoplasm also provides energy and raw materials for the rapid cell divisions that take place in the zygote during its journey to the uterus. This process transforms the zygote from a single cell into a tightly packed sphere of cells referred to as a morula which consequently evolves into a blastocyst. The blastocyst implants in the uterine wall and further develops into an embryo.
Furthermore, the oocyte's cytoplasm possesses a mechanism to prevent polyspermy, the penetration of more than one sperm. Polyspermy leads to a triploid organism with three sets of chromosomes which is incompatible with life. Therefore, the cytoplasm plays a crucial role in ensuring successful fertilization and development of the embryo, making enhancing cytoplasmic retention essential for the survival of the developing oocyte.

Although many cells go through both anaphase A and B motions, occasionally one motion takes precedence over the other. Poleward migration in anaphase requires the separation of the paired sister chromatids. The components that link the chromatids at the centromere are degraded by proteolysis, which causes chromatid separation.
Synapsis is the name given to this action. Crossing over happens during synapsis. DNA is transferred between two nonsister chromatids of a homologous pair of chromosomes during crossing over.
When nondisjunction occurs, the homologous or sister chromatids are drawn to one pole of the cell because the separation does not take place.
Therefore, One daughter cell would have more chromosomes than usual, and one sister chromatid would not split equally during the anaphase of mitosis.
