Answer:
Replicates can be used to measure variation in the experiment so that statistical tests can be applied to evaluate differences. Averaging across replicates increases the precision of gene expression measurements and allows smaller changes to be detected.
Explanation:
<span>Light dependent reactions require an actual source of light, and this is from the sun, for energy to carry out the first stage of photosynthesis. They need solar energy to split a water molecule in order to obtain electrons from hydrogen to be used in fueling photosynthesis. Light independent reactions do not require a light source for energy but rather they use energy that was created by the light dependent reactions to complete the process of photosynthesis in which different carbohydrates for the plant are made.</span>
Could you give more information? For the most part, the dependent variable is what you’re recording. For example, if you wanted to see how plants would grow in different conditions, plant height would be the dependent variable. The height DEPENDS on the condition it was grown in. Hope this helps!
Answer:
75% brown, 25% white
Explanation:
This question involves a single gene coding for color in chickens. The allele for brown color (B) is dominant over the allele for white color (b).
According to this question, a brown rooter with genotype 'BB' was crossed with a white hen (bb). The offsprings in the F1 generation will all possess the 'Bb' genotype and be brown colored. However, if these F1 offsprings are self-mated i.e Bb × Bb, the proportion of F2 offsprings will be 1BB, 2Bb, 1bb.
Since BB, Bb and Bb offsprings are Brown in color and bb is white in color, this means that the expected phenotypic appearance of the F2 offsprings will be:
¾ or 75% brown and ¼ or 25% white
