Well there are 4 things in a dna molecule and that is adenine guanine thymine and cytosine well the DNA molecule keeps the cell moving in the right direction and also helps the cell reproduce and stay healthy
Osmosis is the diffusion of water molecules only through a membrane
Answer:
Option C, Bar graph
Explanation:
A bar graph is used to graphically represent a comparative data set where data belonging to different categories is presented.
Here the different categories shall consists of "different environment exposure" given to plant and under all the “exposed environmental condition” the growth of plant is compared. The categories can be kept on both horizontal and vertical axis of the graph.
Thus, a bar graph (either vertical or horizontal) would be the best to present this data set.
Answer:
15
Explanation:
According to linkage theory, two genes present on the same chromosome tend to get inherited together. So the gametes produced are not equal in number and parental type offspring are observed more in number than the new recombinant types.
Here, normal wings, red eyes (420) and vestigial wings, purple eyes (430) are most in number hence they are the parental type offspring.
Vestigial wings, red eyes = 80 : recombinant
Normal wings, purple eyes = 70 : recombinant
Distance between two genes in cM = recombination frequency = (total number of recombinants / total progeny)*100
= [(80+70)/(420+80+70+430)]*100
= (150/1000)*100
= 0.15*100 = 15cM
