Answer:
25
Explanation:
It depends if number is more than 5 or 5 it will change and if it is less than 5 then it will be same
The agriculture is one of the biggest contaminators of the groundwater. The contamination happens through the usage of chemicals in the agriculture for protection of the plants, or to encourage their growth. Part of those chemicals mange to wash through the soil and reach the groundwater. The majority of the groundwater is connected with the lakes and the rivers, thus the chemicals reach those waters as well. This makes these waters unusable for the humans because they are becoming toxic. The end result would be much less freshwater for usage, be it fro drinking, or for housework, as it can cause serious damage and even death if used, so a shortage of water would be inevitable.
Answer:
C. IBIB
D. IBiO
Explanation:
The blood group system comprises of three different kind of alleles, iA, iB, IO. As we know that a person gets two alleles for both traits, one from father and one from mother, and based on that a person gets its blood group. IA and IB are dominant to IO.
So, if a person has genotype IAIO he will have blood group A and if he has genotype IOIB he will have blood group B because A or B are dominant to O.
However, if a person has blood group O it means that he has genotype IOIO.
So, in this diagram we see that Eric has blood type O, which means that his genotype will be IOIO.
The Eric's mother Melissa has blood group B, which means that she can either had genotype IOIB and IBIB respectively.
Similarly, Eric's grandmother Tricia has genotype B which means that she can have genotype both IOIB and IBIB respectively.
Therefore, both C and D are correct options.

Long before chromosomes were visualized under a microscope, the father of modern genetics, Gregor Mendel, began studying heredity in 1843. With the improvement of microscopic techniques during the late 1800s, cell biologists could stain and visualize subcellular structures with dyes and observe their actions during cell division and meiosis. With each mitotic division, chromosomes replicated, condensed from an amorphous (no constant shape) nuclear mass into distinct X-shaped bodies (pairs of identical sister chromatids), and migrated to separate cellular poles.
