Answer:
Correct me if I'm wrong but I'm pretty sure it is B, Four
Explanation:
Answer:
E. It takes a picture of the brain according to oxygen levels. More oxygen in an area indicates more activity in that area.
Explanation:
Haemoglobin is diamagnetic when oxygenated but paramagnetic when deoxygenated. This distinction in magnetic characteristics leads to tiny variations in the blood MR signal. Since blood oxygenation differs, these variations can be used to identify brain activity depending on the concentrations of neural activity.
All cells have selectively permeable membranes, which means that only they let certain important molecules inside the cell, while the others stay outside the cell.
This occurs by the process of diffusion or osmosis.
Answer:
Explanation:
Based on this information it can be said that this formation between the islands and the mainlands will most likely cause an increase in gene flow between the bird populations. Since the islands and the mainland are now connected birds from both these two different habitats will begin mating and producing progeny, thus causing gene flow to increase between these species.
Answer:
The correct answer is - 30.25%
Explanation:
Allele frequency in a population is the number of a particular allele in the population divided by the total number of all alleles present in the population for the particular gene.
The population has the allele frequency or q = 0 .55
So, the percentage of the white spots moth in this moth population would be -
q^2 = (0.55)^2
q^2 = 0.3025
q^2 = 0.0325 *100
= 30.25 %
