Answer: Independent variable is the Vitamin C and the ashy skin is the dependent variable.
Explanation:
We can change or manipulate the independent variable of the reaction and such change can be observed on the dependent variable. The dependent variable yields the results of the experiment and changes in the dependent variable must be observed attentively to frame the results.
Here, vitamin C is the independent variable whose affect has to be observed on the ashy skin which is the dependent variable of the experiment. Steps of the experiment:
1. We can apply Vitamin C in a form of solution on the ashy skin.
2. Observe the changes on the skin directly and apply for 2-3 times in a day.
3. Observe the changes on the skin after a week.
Answer:
The male creeper and the female creeper are both heterozygous for the creeping trait.
Explanation:
The creeping allele Cr is dominant. For any chicken to have the wild-type long leg attribute, the dominant allele must be absent in its genotype. This means that such an individual would have two recessive alleles, each from either parent.
Hence, in order for two parents to produce wild-type offspring at all, both of them would have to be heterozygous for the creeping trait.
Assuming that the alternate trait is represented by cr allele:
Crcr x Crcr
CrCr Crcr Crcr crcr
<em>The two parents in the above cross are creepers but were able to produce wild-type offspring as a result of both parents being </em><em>heterozygous. </em>
It comes from a unicellular organism named Chloroplast that produces a green pigment substance called chlorophyll, this where oxygen is produced as a by-product of photosynthesis.
