The correct answers are ATMOSPHERE and BIOSPHERE. Nitrogen is most abundant in the ATMOSPHERE, but nitrogen can't be absorbed by the BIOSPHERE without the help of a special bacteria and without undergoing a process called nitrogen fixation.
Answer:
0.05 mg/mL ( B )
Explanation:
Given data:
20 mg/ml starch
2% solution = 2g of solute is in 100g of solvent
<u>Determine the new concentration in mg/ml </u>
Dilution equation = C1V1 = C2V2
new concentration ; applying the dilution factor
dilution factor = 1 : 400 ; ( 2 /400 )g = 0.005 g of solute is present in every 100 mL
∴ new concentration = 0.00005 g / 1 mL * ( 1000 mg / 1g ) = 0.05 mg/mL
Answer:
Mendel's law of independent assortment states that the genes are separated and inherited independently of each other into the gametes.
The corn can be used to study the law if independent assortment as each kernel of the corn is its fruit. Thus, it is a result of sexual reproduction.
Single corn may contain 800-1000 kernels which may have different shape, texture, structure et cetera as result of independent assortment, that is, each kernel receives alleles of genes independent of each other.
For example, a gene responsible for the texture of kernel would be inherited independently of the gene responsible for the color of the kernel.
