1 is C - see first attachment. Genotypes with Y's represent males, and big R represents red eyes, while little r represents white eyes. For example XRxr is a heterozygous (red-eyed) female, and XrYr is a homozygous white-eyed male.
2 is B because the absence of functional proteins and some ribosomes due to the mRNA strand is not as detrimental as the loss of the entire cell.
3 is B. (The insertion of 3 base pairs into a genetic sequence is the length of a single codon, meaning that only one amino acid in the entire polypeptide was added)
Answer: Water will leave the cell and the cell will shrink.
Explanation:
Osmosis is the net movement of water from an area of low to high concentration of solutes through a semipermeable membrane. If none of the compartments contains solutes, then the water moves in either direction between the compartments. <u>However, if we add a solute to one of the compartments, this will affect the probability of water molecules leaving that compartment and moving into the other compartment.</u> The ability of water to move into or out of a cell is called tonicity. The tonicity of a solution is related to its osmolarity, which is the total concentration of all the solutes in the solution. A solution with low osmolarity has few solute particles per liter of solution, whereas a solution with high osmolarity has many solute particles per liter of solution. When two solutions with different osmolarities are separated by a membrane permeable to water but not permeable to solutes, water diffuses from the side with lower osmolarity to the side with higher osmolarity. So, solutions can be:
- <u>Hypotonic</u>: The extracellular fluid has a lower osmolarity than the fluid inside the cell, it is hypotonic with respect to the cell, and the net flow of water will be into the cell.
- <u>Hypertonic</u>: The extracellular fluid has a higher osmolarity than the cytoplasm of the cell, it is hypertonic with respect to the cell and water will flow out of the cell.
- <u>Isotonic</u>: The extracellular fluid and the cell have the same osmolarity so there is no net movement of water.
If a cell is placed in a hypertonic solution, water will leave the cell and the cell will shrink due to the difference in pressure and may even die from dehydration.
Answer:
I think it's the Hawk because it kinda eats every other animal of the list....
Sexual intercourse. The developing of the female egg cells and the production of sperm cells
The answer is pheromones. Hope that helps :)
