How do cell membranes allow genotypes and the phenotypes they produce to stay linked?
How do cell membranes allow genotypes and the phenotypes they produce to stay linked?
ΑΙ A How many different genotypes are possible with this cross of parents? How many phenotypes are possible with this cross of parents, assuming it follows a Mendelian genetics typical dominant recessive pattern?
Question 7 (1 point) Integral membrane proteins stay in membranes because of their small size, which does not allow them to pass through the membrane osmotic pressure from proteins outside the cell. the locations of their polar and non-polar amino acids. diffusion of proteins from the cytoplasm to the membrane.
Cell membranes contain channels that allow Na+ ions to rush in. Consider a channel that has a diameter of 2.81 nm and a length of13.0 nm. If the channel has a resistance of 16.5 GΩ, what is the resistivity ? of the solution in the channel?
what is the general structure of detergents? how do these affect membranes and membranes proteins? (this question is essential cell biology 4th edition chapter 11 membrane structure))
Cell membranes do all of the following EXCEPT: provide attachments between cells. provide shape and structure to a cell. isolate the cell's contents from the external environment. allow communication between cells regulate the movement of substances between the cell and the interstitial fluid.
How do viruses acquire an envelope? Viruses manufacture cell membranes because it is encoded in their nucleic acid. Animal viruses don't make membranous envelopes; these are only produced in phage viruses. Only DNA viruses make envelopes because they have a gene for phospholipid production. When virus are released from host cell, they take the host cell membrane along with synthesized viral glycoproteins.
A cell membrane has a thickness of about 7.4 nm. How many cell membranes would it take to make a stack 1.8 in. high? membranes
2. The history of cell membranes serves as an excellent example of how the development of new tools in cell and molecular biology can contribute to our knowledge about a particular cell process or organelle. Explain how each of the following was significant to our current model of the cell membrane. a. Freeze-fracture b. Antibodies, Cell Fusion and Capping c. Concanavalin A and FRAP d. Cytoskeleton and Extracellular Matrix Proteins
1-what role do the steep Na+ and K+ electrochemical gradients across animal cell membranes play? 2- How is the potential energy of an electrochemical gradient released?
can someone explain how a is sex-linked and c is autosomal. also, need help with e please. Your hobby is breeding fancy guinea pigs for people who like that sort of thing. You set up a cross in which the parents are true-breeding and have phenotypes as follows: the father has black fur and a long tail, and the mother has white fur and is tailless. They produce offspring in which all the males are white and have long tails...
