Answer:
The more strongly the ORN is activated, the fluorescence decreases.
Explanation:
Olfactory receptors are commonly known as olfactory ordants receptors that are located on the cell membrane of olfactory receptor nerves. They are mainly used for the detection of different types of smell.
Olfactory receptor response is used t measure the functioning of the olfactory receptor. The fluorescence element labelled with calcium used in this type of fluorescence. The activation of ORN can be measured by the fluorescence activity. The decrease in fluorescence is associated with the increase in the activation of ORN.
Thus, the correct answer is option (b).
Answer:
2.01%
Explanation:
Multiply 0.0201 by 100 to get 2.01%.
Stabilizing selection, directional selection and disruptive selection are the three types of natural selection.
What are these types of selection?
Natural selection is the process wherein organisms get better adapted to their environments and tend to survive and produce more offsprings. It is basically a mechanism of evolution which favors those organisms that can better adapt to their environment.
Directional selection: this theory states that an extreme phenotype (a characteristic or trait) is favored over other phenotypes and this causes the allele frequency to shift in favor of the extreme phenotype over time. A particular trait, if favorable, will be expressed in the population at the most beneficial frequency.
Stabilizing selection: in this type, meaning a non-extreme trait is favored instead of one of the two extreme traits. Stabilizing selection is said to be the most common mechanism for natural selection, because most traits do not change drastically over time.
Disruptive selection: This selection is bimodal. It favors both of the extreme traits in a population.
So therefore, stabilizing selection, directional selection and disruptive selection are the three types of natural selection.
