Answer:The permeability increases as the duration of exposure to light
is prolonged.
Explanation: The permeability of Paramecium to NH4OH is greater when the cells are exposed to light than it is when they are in darkness. So when the cells are exposed to monochromatic red light, it becomes greater as the wave lengths shorten and is greatest in the near ultra violet.
Answer: TT
Explanation: We know that the ability to roll your tongue is a dominant trait from your parents, and the inability to roll your tongue is a recessive trait. So the genotype would be TT.

This is because maybe that allele for the trait is recessive and the person is heterozygous.
If the person is heterozygous, it means that they have both the dominant and recessive allele for a trait. And by dominant and recessive, if dominant allele exists, no matter if recessive allele exists or not, the characteristic controlled by the dominant allele must be shown. This is their phenotype, which is the observable characteristics.
For example, there are 2 alleles for controlling the eye color. Brown allele is dominant, while blue is recessive. Just like the question above, if the person has an allele for blue eye color, but they have the brown color allele too, their phenotype would be brown eye color, as the brown color is dominant over blue eye color. This matches the requirements of having the allele for a particular trait but not showing the phenotype of that.
I think the answer is dysmorphic ideation because bulimic patient's see themselves in a mirror and are always criticising the way they look..to them they see an overweight person in the mirror, but in reality they could be an ideal weight..
