explain why the surface area to volume ratio for a cell membrane and cytoplasm volume limits the size a cell can achieve and still maintain homeostasis

/in /by

*write an essay that explains why the surface area to volume ratio for a cell membrane and cytoplasm volume limits the size a cell can achieve and still maintain homeostasis refer to the lab attached Be sure to give specific examples of how different cells deal/overcome these limits in order to carry out their functions. For example, the sciatic nerve is an example of a rather large cell that is designed in such a way with membrane and volume dimensions that allow for it to maintain its size so that it can perform its function.

Characteristic Dominant Gene Recessive Gene Horn texture Spiral (S) Smooth (s) Coat color White (C) Pink (c) Blood powers Magical (B) Non-magical (b) 1. Electra and Ranger both have white coats but their son Trotter is pink! How is this possible? Give the genotypes of both Electra and Ranger and show the Punnett square. 2. Forester does not have magical blood and he wants to make sure that none of his children have to go through the ridicule that he has gone through. What would the genotype of his wife have to be to ensure that all of his children have magical blood? 3. (a) Celestia’s genotype is cc. What is her phenotype? (b) Romper’s genotype is a carrier for coat color. What is his genotype? (c) What is the chance their son will be white? 4. (a) Elita has a spiral horn. What is her genotype? (b) Considering karyotypes don’t show genes and the cost of sequencing is prohibitive, what type of test can we do to determine Elita’s genotype? (c) If Chaser has a smooth horn and all of their offspring have spiral horns, what is Elita’s genotype? Show your work. 5. (a) Jumper is heterozygous for horn texture and homozygous dominant for blood powers. What is his genotype? (b) List the gametes that Jumper can produce. (c) Airy is homozygous recessive for horn textures and heterozygous for blood powers. What is her genotype? (d) List the gametes that Airy can produce (e) What is the phenotypic ratio of their children? 6. (a) There is a rare but terrible condition in which the horn isn’t formed. A missing horn (M) is an autosomal dominant condition whereas the presence of the horn is the recessive condition. Deva is heterozygous. What is her phenotype? (b) If she marries Cracker who is homozygous recessive, will any of their children have the condition? Show your work. (c) Will any of their children be carriers for this condition? Explain. 7. What is the phenotypic ratio for the mating of Stroller (CcBb) and Snowy (CcBb)?

Describe the fluid mosaic structure of cellular membranes.

/in /by

Our cells are bounded by delicate cell membranes that separate living cells from their abiotic environment. Cell membranes control what enters and leaves our cells. Eukaryotic cells, like ours, are further subdivided into membrane compartments, the organelles, that conduct the various functions of our cells. The membranes surrounding and within our cellular organelles control what enters and leaves the organelles and further subdivide organelles into smaller, separate compartments, each with its own special chemistry.
To post your answer.
How do the membranes of cells and the organelles they contain control the movement of materials?
1. Describe the fluid mosaic structure of cellular membranes.
2. Describe the diffusion of materials through the phospholipid bilayer.
3. Describe the diffusion of materials through passive transport proteins.
4. Explain the role of ATP in the active transport of materials across a membrane.
5. Describe endocytosis and exocytosis and explain the difference between the two.
