The two major components of blood are the blood cells and fluid plasma. The blood cells make up about 45% of the blood composition, and the rest of the 55% of the blood is made up of plasma. The blood cells are of three types that are red blood cells (erythrocytes), white blood cells (leukocytes), and platelets (thrombocytes).

Summary Introduction

Introduction:

The two major components of blood are the blood cells and fluid plasma. The blood cells make up about 45% of the blood composition, and the rest of the 55% of the blood is made up of plasma. The blood cells are of three types that are red blood cells (erythrocytes), white blood cells (leukocytes), and platelets (thrombocytes).

Expert Solution & Answer

Answer to Problem 1RAC

The correct answer is option (e) all of these are correct.

Explanation of Solution

Explanation/justification for the correct answer:

Option (e) all of these are correct. Blood functions to maintain osmolarity through ions and electrolytes, protects against foreign substances through immune cells, contains platelets for clot formation and maintains body temperature. So, the correct answer is option (e).

Explanation for incorrect answer:

Option (a) clot formation. Blood contains platelets that are responsible for the formation of a clot that stops bleeding, but that is not the only function of blood. So, this is an incorrect option.

Option (b) protection against foreign substances. Blood contains white blood cells and immune cells that function to protect the body against infections and maintains immunity, but that is not the only function of blood. So, this is an incorrect answer.

Option (c) maintenance of body temperature. The blood maintains body temperature by the transport of hormones that helps to regulate body temperature through vasoconstriction and vasodilatation, but that is not the only function of blood. So, this is an incorrect answer.

Option (d) regulation of pH and osmosis. Blood helps to maintain pH and osmolarity by providing the ions that balance the pH and water-electrolyte balance in the body, but that is not the only function of blood. So, this is an incorrect answer.

Conclusion

The blood helps to maintain pH and osmolarity; it helps in protection, maintenance of body temperature, and helps in clot formation. Hence, the correct answer is option (e) all of these are correct.

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:
