Question 5

Biology
1 answer:
Ad libitum [116K]3 years ago
3 0

Answer:

My experiment showed that energy production, or respiration, occurred in yeast even when little oxygen was present. During exercise, the lungs must work hard to take in oxygen, which then circulates to the body parts that need it. The ability to preform anaerobic respiration for short periods of time allows humans to sustain activity, even when oxygen is limited in the body.

Explanation: from plato, so change it a bit.

Why would different restriction enzymes cut the same DNA molecule into different numbers of fragments
Nataly_w [17]

Because different restriction sites are used by different restriction enzymes to cleave DNA.

<h3>What is restriction sites?</h3>
  • A restriction site is a segment of DNA with a base pair count between 6 and 8 that binds to a certain restriction enzyme. There are numerous restriction enzymes that have been identified from bacteria. By cleaving the viral DNA, they naturally render invasive viruses inactive.
  • Restriction enzymes are beneficial in a variety of contexts. Each organism has a unique DNA sequence, so each one will have a unique arrangement of restriction sites.

We are pretending that I am testing to see if Vitamin C cures ashy skin. You must write out EVERY step of the study that I must
denpristay [2]

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.
