Chapter 5, Problem 9TYU
FOCUS ON EVOLUTION
Paramecium and other unicellular eukaryotes that live in hypotonic environments have cell membranes that limit water uptake, while those living in isotonic environments have membranes that are more permeable to water. Describe what water regulation adaptations might have evolved in unicellular eukaryotes in hypertonic habitats such as the Great Salt Lake and in habitats with changing salt concentration.

- You said that " However, if the salinity level is too extreme or the exposure is prolonged, it could lead to cellular damage and potentially death. In summary, while marine mussels are adapted to live in a hypertonic environment and are osmoregulators, exposure to extremely high salinity levels could still be harmful to them." Where are you finding this I can't seem to find this on the internet do you have a research paper to show this. Thank you for your help and timearrow_forwardWhich of the following is true of the flagellum in eukaryotes? It is a long, thin extracellular (exterior) structure, with a basal motor embedded in the cell membrane/cell wall. It is identical to the archaeal flagellum (archaellum) in composition and structure, but very different in composition and structure from bacterial flagella. It is a long, thin structure containing bundles of microtubules and motor proteins, all within the plasma membrane. Eukaryotic cells do not possess flagella.arrow_forwardDraw one elodea cell (freshwater plant) after being in saltwater.

- Paramecia live mostly in freshwater and move with the use of structures called cilia. They utilize contractile vacuoles to expel water that enters the cell by osmosis. Euglena are unicellular organisms that use flagella for movement and chloroplasts for photosynthesis. They are found in freshwater and saltwater.

Given the properties of the water in the prebiotic ocean. One would expect that H2O and ions would: A) move through the fatty acid layer of the phospholipid bilayer out of the pre-cell, B) be unable to move through the bilayer, C) move through the phosphate groups in the pre cell phospholipid bilayer and move into cell, D) dissolve the bilayer, E) transport proteins into the pre cell.arrow_forwardWhat Osmotic conditions would be favored by Plant and Animal cells?

- A cell is moved from its normal environment in a freshwater river and is suddenly placed into the ocean. What would be the effect of this change in environment on the cell? O 1) It would shrivel because it would lose water. O 2) It would shrivel because it is responding to a hypotonic environment. O 3) It would swell because it is experiencing a hypertonic environment. O 4) It would swell because it would gain water. O 5) Nothing would happen to the cell.arrow_forwardWhen an animal cell is placed on an isotonic solution, water molecules will A) Move out of the cell, resulting in shrinkage B) move into the cell until it bursts C) move into and out of the cell at equal rates D) stop moving need help for this, thanksarrow_forwardquick answers to mc pleasearrow_forward
