The nasal septum is a cartilage and bone structure in your nose. The septum separates the nasal cavity into two halves. The septum has "deviated" when it is off-center or leans to one side of the nasal cavity. This is referred to as a deviated nasal septum by doctors.

Expert Solution & Answer

Answer to Problem 1DYKB

Correct answer :

The correct answer is option (a) perpendicular plate of the ethmoid bone and vomer.

Explanation of Solution

Explanation/justification for the correct answer :

Option (a) perpendicular plate of the ethmoid bone and vomer. The septum's bony portion consists of the ethmoid bone's perpendicular plate, the vomer, and the maxillary crest, which is supported by the maxillary and palatine bones. The septum's caudal portion is formed by quadrangular cartilage. So, the correct answer is option (a).

Explanation for incorrect answer :

Option (b) perpendicular plate of the ethmoid bone only. The nasal septum is formed by combining the vomer and the ethmoid bones. So, this is an incorrect option.

Option (c) nasal bones and perpendicular plate of the ethmoid bone. The nasal bones are two short oblong bones that differ significantly in size and shape depending on the organism. They are placed beside each other in the middle and upper part of the face, and their roundabout aids in the formation of the bridge of the upper one-third of the nose. So, this is an incorrect option.

Option (d) vomer and sphenoid bones. The sphenoid is one of the twenty-two bones that make up the skull and serves to connect the neurocranium to the facial skeleton. So, this is an incorrect option.

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:
