Answer:
Option C, Aneuploidy
Explanation:
Aneuploidy is defined as the condition when offspring/daughter cell has abnormal number of chromosomes.
In the process of nondisjunction, the pair of homologous chromosomes do not separate and hence the sister chromatids fails to separate.
Hence, option C is correct
Both "depends upon the binding of that substance to a specific site on the membrane protein" and "depends upon movement of proteins from one side of the membrane to the other" are correct.
The saturation effect prevents statement 2 from being true.
The answer is no, high biological fitness in one environment doesn’t have to be high in another environment.
Biological fitness is a term used in evolutionary biology and it is the quantitative representation of how a genotype (or phenotype) is successful (reproductively) in a certain environment. Fitness depends on environment so it changes if the environment changes. The fitness of a genotype is manifested through its phenotype, which is affected by the environment.
Well it helped the animals and humans grow the population.
