According to the fluid mosaic model, membranes are held together by hydrophobic interactions. Considering the forces that some cells may experience, why do membranes not break apart every time an animal moves?

Expert Solution & Answer

Summary Introduction

To explain: That why do membranes not break apart every time an animal moves.

Introduction: The cell membrane is also called cytoplasmic membrane or plasma membrane. Cell membrane is a biological membrane. The major function of the cell membrane is to protect the cell from its surroundings.

Explanation of Solution

The fluid mosaic model describes the structure of cell membrane. In fluid mosaic model, a flexible layer is composed of lipid molecules and is interspersed with large molecules of protein. As the name suggests for this model (fluid mosaic model), the cell membranes have some degree of fluidity. The degree of fluidity differs with the membrane composition, while in all membranes; phospholipids are able to move about inside the membrane. The phospholipid bilayers are spontaneously formed due to the hydrophobic and hydrophilic opposite ends of phospholipid molecules. Thus, when stressing forces occurs to damage a membrane, automatically adjacent phospholipids move to fill in the opening. Therefore, the membrane does not break apart every time an animal moves.

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:
