In red-green colorblindness, individuals cannot perceive the colors red and green in the same way as individuals with full color vision. Full color vision is coded by a dominant allele (B) on the X chromosome. Red-green colorblindness is caused by a recessive allele (b) on the X chromosome.

a. Identify the phenotype of a female with the genotype XBXb.
b. Identify the phenotype of a male with the genotype XBY.
c. Draw a Punnett square for the cross X uppercase B, X lowercase b crossed with X uppercase B, Y, and identify the following:
the percentage of offspring expected to be male and colorblind
the percentage of offspring expected to be female and colorblind
d. Explain why red-green colorblindness occurs more frequently in males than in females.

a neutral ph of 7 and normal organism temperature is needed for a certain enzyme to be effective.  

what would happen to the enzyme if the ph and/or temperature fluctuate greatly from the norm?  

a.the enzyme’s hydrogen bonds will break.  

b.the activation energy will increase.  

c.more product will be formed.

d.the ideal temperature and ph for the enzyme function will decrease.  

as in mitosis, dna replication occurs during interphase.   in meiosis, it occurs specifically in s phase of interphase 1.

the answer is b.) hydrogen bonds between bases.

the cells uses some of the atoms of the glucose molecules to atp molecules. the atoms of the glucose molecules will then be converted into energy which will be eventually stored in atp. the energy produced which are stored in atp are coming from the glucose’s chemical bonds.
