Answer:
Option D, Five radish plants are grown in sunlight, while another five radish plants are kept in the dark.
Explanation:
In a controlled experiment, impact of one independent variable is studied on the dependent variable.
Here in this study sunlight is the independent variable while the radish plant is dependent variable.
The researcher wants to study the effect of sunlight on radish plants when they are exposed to it and compare it to the effect created on radish plants that are kept in dark.
Hence option D is correct.
Answer:
B. The breaking of the chemical bond between the 2nd and 3rd phosphate
molecules in ATP.
A, the others are unrealistic speeds.
Answer:
The correct answer is option D. True tissues.
Explanation:
The cell that made sponge does not form the tissue however sponge have cells that play important role and specific for specific function but does not have true tissues.
In other animal phyla cells form tissue or organ or organ systems and called as true tissues.
Thus, the correct answer is option D. True tissues.
Answer:
100%
Explanation:
This question involves two genes in guinea pigs; one coding for fur color and the other for fur length. The alleles of black fur (B) and short fur (F) is dominant over the alleles for brown fur (b) and long fur (f).
In a cross between two offsprings with genotypes: BBFF x bbff, the following gametes will be produced by each parent:
BBFF - BF, BF, BF, and BF
bbff - bf, bf, bf, bf
Using these gametes in a punnet square (see attached image), one will notice that all of the offsprings will have the genotype: BbFf i.e all or 100% of the offsprings are heterozygous for both of the genes or traits.
