Sister chromosome exchanges are recombination events that occur between homologous chromosomes and are often the result of exposure of the cell to DNA damaging agents. 
Cross over, or recombination, is the exchange of chromosome segments between non sister chromatids in meiosis. Crossing over creates new combinations of genes in the gametes that are not found in either parent, contributing to genetic diversity.

How many moles would there be in 100 g of glucose? In 500 g of glucose? SHOW WORK
vivado [14]

Answer:

a) 0.56moles

b) 2.78moles

Explanation:

The number of moles can be calculated by using the formula;

Mole (n) = Mass (M) ÷ Molar mass (MM)

For a glucose molecule, with chemical formula: C6H12O6

Where atomic mass of C= 12, H=1, O= 16

Molar mass of C6H12O6= 12(6) + 1(12) + 16(6)

= 72 + 12 + 96

= 180g/mol

a) In 100g of glucose;

Mole = 100/180

Mole = 0.56moles

b) In 500g of glucose

Mole = 500/180

Mole = 2.78moles

Explain the role of bacteria in the nitrogen cycle
Oksanka [162]

Bacteria is important because this bacteria binds hydrogen molecules with the gaseous nitrogen to form ammonia in the soil.  During assimilation, or when plants take up nitrates from the soil, bacteria aid in the process with the plants in making ammonia. Animal wastes is also a major place where bacteria thrives and produces ammonia. The process in which assimilation occurs in plants, and then bacteria converts the nitrates to ammonia is called ammonification.  From the conversion of ammonia to nitrites, bacteria also aids in this process called nitrification. The nitrifying bacteria mostly present in soils, oxidize ammonia into nitrites, and from nitrites to nitrates.

Finally, the process of denitrification also has bacteria present to aid in converting nitrates back into a gaseous form of nitrogen in the atmosphere.
