Expert Solution & Answer

Explanation of Solution

Basic functions of nutrients are to help in the proper functioning of the body and keeping the body healthy.

The two major functions of nutrients are:

Energy store:

Nutrients acts as fuel for the metabolic processes in the body. The primary fuel for energy is carbohydrates. In the absence of carbohydrates, the fats are consumed through the metabolic pathways to provide energy. When there is an absence of both carbohydrates and fats, proteins act as fuel by the body. So, all three types of macronutrients provide ATP. ATP is the primary energy currency of the cell. It stores energy in the form of phosphate ester bonds. When these bonds are broken, there is a release of energy for the proper functioning of biological activities.

Building blocks:

The structural components which form a human body are composed of the nutrients. Protein is the major component of the body which makes up the internal organs, muscles, skin, and blood. Proteins help in the formation of muscles and provide strength to them. Carbohydrates and lipids are in-between the complexity between nucleic acids and proteins. Fat forms an adipose tissue that acts as a cushion and insulates the body.

In this way, nutrients are helpful in storing energy and building blocks of the body.

Conclusion

Hence, the two major functions of nutrients are storing energy store and building blocks of the body.

Question #3: In the KeyGene paper, the authors state that it would be useful if pollen from an apomict would transmit apomixis-inducing genes to the female in the cross (assuming the pollen is viable). Assuming there was just one gene conferring gametophytic obligate apomixis, and that the two parents are inbreds, what would be the consequences of such a cross if: a) The apomixis was a dominant trait? Indicate the genotypes and phenotypes (apomict or non- apomict) of the parents, F1 and F2 generations. Remember to include the expected genotypic and phenotypic ratios (or percentages) in the F1 and F2 generations, and to position the female first (left side) in the parental cross. b) The apomixis was a recessive trait? Indicate the genotypes and phenotypes (apomict or non- apomict) of the parents, F1 and F2 generations. Remember to include the expected genotypic and phenotypic ratios (or percentages) in the F1 and F2 generations, and to position the female first (left side) in the…

Question #5: Assume that two genes are identified that confer gametophytic facultative apomixis in soybean. The genes show independent assortment. Recessive alleles at both loci are required for the facultative apomixis. Facultative apomixis is triggered when the temperature at pollination is above 20 degrees C. At temperatures below 20 degrees C, all reproduction is sexual, independent of genotype. A facultative apomict male, capable of producing viable pollen, was crossed with a sexually reproducing female. Assuming the parents are completely inbred, what are the predicted phenotypic ratios (apomict: non-apomict) for the F1, F2, and DH (F1-derived) generations at each of the following temperatures*: a) 15°C? b) 25°C? *for full credit, show crosses and genotypes where appropriate. Remember to position the female first (left side) in the cross. Type your answer here:
