Glucose
Glucose, a small polar solute, uses a membrane transporter (a protein carrier) to cross the plasma membrane via facilitated diffusion. In simple diffusion, small nonpolar and lipid-soluble substances (including gases) diffuse directly through the lipid bilayer.
Answer:
There's 25% probability that their next child will be normal, and 75% of it being a dwarf.
Explanation:
Achondroplasia (A) is a dominant trait.
Two achondroplastic dwarfs (A_ x A_) have a dwarf child (A_) and a normal child (aa). The second child must be aa because if it had a dominant allele it would also be dwarf.
The only way for two achondroplastic parents to have a normal child is that <u>they are both heterozygous (Aa) for this gene.</u>
The cross Aa x Aa would produce the following offspring probabilities:
- 1/4 AA - dwarf
- 2/4 Aa - dwarf
- 1/4 aa - normal
So there's 1/4=25% probability that their next child will be normal, and 3/4=75% of it being a dwarf.
His genotypes are X to the power of H and X to the power of h the second numbers are exponents so it goes X to H and X to h i hope this makes sense i couldn't make them into exponents but i tried :)
In the given case, cell A is placed in 2 % solution of glucose and cell B is placed in 5 % glucose solution. Both the solutions are hypotonic, and when a cell is placed in a hypotonic solution, then the greatest concentration of water will be outside of the cell. Therefore, water will enter the cell and occupies the central vacuole.
However, cell B is placed in a more concentrated solution, so it will swell less in comparison to cell A, which is placed in a less concentrated solution. Hence, the correct answer is option A, that is, Cell A will swell more than Cell B.
