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 football will hit the ground 2.11 seconds later.
Explanation:y = y0 + v0yt + ½ayt
2
0 = v0sin t + ½ayt
2
0 = t(v0sin + ½ayt)
t = 0 or v0sin + ½ayt = 0
½ayt = – v0sin
=
−20sin
=
−2(18.0)sin(35.0°)
−9.8

Plasmid is a small, circular, double-stranded DNA molecule that is distinct from a cell's chromosomal DNA. Plasmids naturally exists in bacterial cells, and they also occur in some eukaryotes. The genes carried in plasmids provide bacteria bacteria with genetic advantages, such as antibiotic resistance. To know whether the cell carry recombinant plasmids; only cells with a plasmid will reproduce and also the color of the colonies in E. coli plasmid recombination experiments allows scientists to distinguish colonies with recombinant plasmids from those without.
