To answer: How do the structures of arteries, capillaries, veins, and lymphatics differ and how these differences reflect on each of its function? Introduction: The transportation of oxygen and nutrients and exclusion of metabolic waste products from the body are the primary functions of the circulatory system. This system is involved in circulating blood and lymph throughout the body. It consists of a heart, lymph, blood, blood vessels, lymphatic vessels, and glands.

Expert Solution & Answer

Explanation of Solution

The arteries and veins possess three distinct layers. The primary tissue of the arteriole is made up of smooth muscles, whereas the veins are primarily made up of connective tissues. The smooth muscles of the arteries are found to be reflective with their capacity in order to withstand high pressures. Also, they respond to certain changes in the body by contraction or relaxation of the arteries.

The capillaries are made up of a single layer of endothelial cells that were attached to the basement membrane spacing between the endothelial cells. This would allow the entry of certain components to pass in and out of the capillaries thereby allowing the fluid and cellular exchange.

The lymphatic vessels possess thin valves and walls resembling that of the veins. These thin walls and valves aid in adsorption and flow of lymph through the lymphatic vessels.

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:
