Answer:
The correct answer is : B) Wavelength of light is the only variable that has been changed between groups.
Explanation:
In this three plants in three different conditions shows three different outcomes so their is sufficient replication to draw a conclusion. The wavelength of the light affects the growth of the plant. UV light has very low wavelengths below 400 nm than the photons required similarly Infrared light has higher wavelengths that is low energy light, UV can cause wilting and leaf burn.
So, the wavelengths of the light and growth of plant are related and this experiment only wavelengths of the lights are changed.
Thus, the correct answer is : B) Wavelength of light is the only variable that has been changed between groups.
Answer:
1/4.
Explanation:
The autosomal dominant trait means that the trait is visible in homozygous dominant and in heterozygous condition. The X linked recessive trait will be pass down from mothers to their sons and daughters will show the trait in homozygous recessive condition only.
The man is achandroplastic dwarf ( Aa) with normal vision (XY ) is married with woman that has normal height (aa) with color blind (XhXh). They have a daughter who is dwarf ( Aa). The probability of being dwarf can be calculated by the cross Aa × aa. The offspring are Aa, Aa, aa, aa. Means 1/2 are the probability of being hetterozygous for achondroplastic . The vision probability is calculated by cross XY and XhXHh. The probability that female is heterozygous is 1/2.
So, the heterozygous probability for both trait is 1/2× 1/2 = 1/4.
