The 3 colors are green, red and blue
Answer:
The correct answer would be - marbles represent alleles for a particular trait that has an allelic frequency of 0.5 in this simulation.
Explanation:
In this given representation or simulation to illustrate genetic drift, a student used marbles of different colors. She used 20 red and 20 yellow marbles in a population of 40 individuals. In this simulation, she used each marble color red and yellow to represent the allele for a particular trait.
That means red marbles represent alleles that are specific to a trait of a gene and similarly yellow marble represents another trait of the same gene. It is also represented that both alleles are present in the same number which means they have alllelic frequency of 0.5.
Answer:
When a mustard plant seedling is transferred to an environment with higher levels of carbon dioxide, the new leaves have a lower stomata-to-surface-area ratio, it is because the concentration of carbondioxide is high in the surrounding environment so the plant produce small leaves having less number of stomata. If the concentration of carbondioxide is lower so big leaves are produced having maximum number of stomata.
Answer:
B. All antigen receptors produced by a single B or T cell are identical and bind to the same epitope.
Explanation:
Antigen receptors are antibody protein anchored to the B-cell membrane.
They are all identical when the antigen receptors is located on one type of B cell making Binding between the receptor and epitope to occur since its structures are complementary. It's not identical when the antigen receptors is located on different types of B cell
