The best thing to do is this:
the subjects in the experimental group should be given large, daily dose of vitamin C while the control group subjects should be given a daily dose of sugar pills that are disguised as vitamin C.
The research can then observe the differences between the two groups.
Answer:
The right answer for the blank is cleavage.
Explanation:
After fertilization the next step is cleavage in which zygote divide mitotically. As the embryo move from oviduct down the fallopian tube it divide into two cell and then four cells. four cell embryo is known as blastomere.
Answer:
The correct option is D. The average mass of plants exposed to 3 g of herbicide was 10g.
Explanation:
As the vertical axis is labelled as average plant mass, it will make the y- coordinate.
As the horizontal axis is labelled as Herbicide (g/plant), it will make the x-axis.
The coordinates for the given value are (3,10). 3 will be the value of the x- coordinate. Hence, it will show the average mass of the plant at the plotted point which will be 3 g.
10 will show the value of the y- coordinate which will be the amount of herbicide given to the plant.
Hence, Dis the correct option.
If purple is dominant, the genotype of the purple flower could be PP or Pp, as both would give a purple colour. However, if the crossed flower turned out to be white, we could say with certainty that the genotype of the purple flower is Pp as the genotype of the white crossed flower would be pp, which would not be possible if the purple flower's genotype was PP.
The answer is option 1, 3, 5,7, and 10
