What is food energy in the form of glucose?
tiny-mole [99]
<span>Glucose is the human body's key source of energy as it provides energy to all the cells in our body. Glucose also is critical in the production of proteins, lipid metabolism and is a precursor for vitamin C production.</span><span><span>Glucose is the sole source of fuel to create energy for all brain and red blood cells.</span> The availability of glucose influences many psychological processes. When glucose levels are low, psychological processes requiring mental effort l(self-control, critical thinking and decision-making) become impaired.

Suppose two independently assorting genes are involved in the pathway that determines fruit color in squash. These genes interac
makvit [3.9K]

Answer:

100% yellow fruit color, Yyww.

Explanation:

<u>Available data</u>:

  • two independently assorting genes
  • the W allele codes for a dominant white phenotype
  • w allele codes for a colored squash
  • The allele Y codes for a dominant yellow phenotype
  • the allele y codes for a recessive green phenotype
  • The phenotypes from the first locus will always mask the phenotype produced by the second locus if the dominant allele (W) is present at the first locus. This masking pattern is known as dominant epistasis

Epistasis means "interruption" and refers to interactions between genes located in different loci in the same chromosome. An “epistatic gene” can alter, influence, or suppress the expression of a "hypostatic gene". When the epistatic gene is dominant, the interaction is known as "dominant epistasis".

W suppresses the expression of Y and y, this means that whenever W is present, the fruit is white. If W <u>is not</u> present, the fruit color can be expressed.

So, the proposed cross in the present problem occurs between a green fruited individual and yellow fruited individual, which suggests that W is absent.

<em>Genotype for Green fruit: yyww</em>

<em>Genotype for purebred Yellow fruit: YYww</em>

Cross:

Parental) YYww    x    yyww

Gametes) Yw  Yw  Yw  Yw  yw  yw  yw  yw

Punnet square)    Yw       Yw       Yw      Yw

                 yw    Yyww  Yyww  Yyww  Yyww

                 yw    Yyww  Yyww  Yyww  Yyww

                 yw    Yyww  Yyww  Yyww  Yyww

                 yw    Yyww  Yyww  Yyww  Yyww

F1) 100% Yellow fruited plants, Yyww

As these two genes assort independently, we can also represent the cross for each gene by separate, like this:

For w gene:

Parental) ww  x  ww

Gametes) w w w w

Punnet square)  w     w

                 w     ww   ww

                 w      ww  ww

F1) 4/4 or 100% colored-fruits

For Y gene:

Parental) YY  x  yy

Gametes) Y Y y y

Punnet square)  Y     Y

                 y     Yy     Yy

                 y     Yy     Yy

F1) 4/4 or 100% yellow fruits, Yy.

Effectus [21]

Explanation:

What happens during daytime is, oxygen that gets trapped between filaments of algae, moves them to the surface  and during night as O2 is not produced, they slowly sink to lower depths, and you don't see them
