Answer: The alleles of a plant that is heterozygous for seed color can be represented as Y for dominant allele for yellow seed and y for recessive allele for green seed.
Explanation: A plant that is heterozygous for seed colour has one dominant allele and one recessive allele for seed colour. If Y represents the dominant allele for yellow seed colour and y represents the recessive allele for green seed colour, therefore the plant has a genotype of Yy. A dominant allele is one that has the ability to mask the effect of a recessive allele while a recessive allele is one whose effect is masked by a dominant allele. Dominant alleles are denoted with upper cases while recessive alleles are denoted with lower cases. A plant that is heterozygous for seed colour with genotype Yy will manifest outwardly as Yellow seed colour due to the presence of the dominant allele Y.
Answer:
2.glucose move into chamber B faster than fructose
Explanation:
- Facilitated diffusion: refers to the transport of hydrophilic molecules that are not able to freely cross the membrane. Channel protein and many carrier proteins are in charge of this <u>passive transport</u>. If uncharged molecules need to be carried <u>this process depends on concentration gradients</u> and molecules are transported from a higher concentration side to a lower concentration side. If ions need to be transported this process depends on an electrochemical gradient. The glucose is an example of a hydrophilic protein that gets into the cell by facilitated diffusion. Facilitated diffusion is a passive transport process because the cell does not need any energy to make it happen.
The exposed scenario is an example of facilitated diffusion, a process that occurs in favor of the concentration gradient, and which rate depends on the concentration of molecules in each side of the membrane, in this case, glucose and fructose, among other factors that might also influence the diffusion rate. So, as the concentration of glucose is higher in chamber A (80%), and lower in chamber B (20%), in comparison with fructose, the first one will diffuse faster than fructose. The difference in concentration between both chambers is sharper in glucose, so its transport is faster than the fructose transport, which will also diffuse but at a lower rate.
