Answer:
8 different combinations of gametes can be produced by this mosquito, assuming no homologous recombination between chromosomes
Explanation:
The mosquito has 6 chromosomes. This means that means it has 3 pairs of homologous chromosomes. Basically, we can assume the number of different gametes by 2 to the power of 3 as their are 3 homologous pairs. This means 2×2×2 which will be equal to the amount of eight. Hence, eight different combination of gametes will be produced.
The theory of evolution proposed that a series of catastrophes or mass extinctions followed by repopulation could explain why species change over time
Answer:
Animal cells tend to do best in an isotonic environment, plant cells tend to do best in
a hypotonic environment. This is demonstrated in the attached PDF.
Explanation:
A cell that does not have a rigid cell wall, such as a red blood cell, will swell and lyse (burst) when placed in a hypotonic solution, a process called cytolysis. Cells with a cell wall will swell when placed in a hypotonic solution, but once the cell is turgid (firm), the tough cell wall prevents any more water from entering the cell. When placed in a hypertonic solution, a cell without a cell wall will lose water to the environment, shrivel, and probably die. In a hypertonic solution, a cell with a cell wall will lose water too. The plasma membrane pulls away from the cell wall as it shrivels, a process called plasmolysis.
I hope this helps. If not I am really sorry!
Answer:
An increase in the number of H+ ion in the lake with many aquatic would cause cell shrinkage by the removal of water from the cell.
Explanation:
Every organism tries to maintain a constant PH inside their body to regulate the homeostasis of their body.
An increase in the number of H+ ion or proton in a lake will increase the osmotic pressure of the water present in the lake.As the osmotic pressure of Lake"s water is increased it will draw water out from the the cells of aquatic organism causing the cells to shrink thus decreasing the volume of the cell and if the H+ ion concentration rises at a high level cell death can occur.
Answer:
Nucleic acids are polymers of individual nucleotide monomers. Each nucleotide is composed of three parts: a 5-carbon sugar, a phosphate group, and a nitrogenous base.
