If a particular strand of DNA is found to be 27% adenine, how much guanine would it contain

Biology
1 answer:
Naddika [18.5K]3 years ago
6 0

Answer:

You have 20% of adenine. If you have 20% of adenine than you have 20% of thymine, because the amount of adenine and thymine is equal. 20% plus 20% is 40% of adennine and thymine. From 100% DNA bases subtract 40% and you will get 60%. Then divide this by 2 and you will get 30%. 30% of guanine and 30% of cytosine, because their amounts are equal in the DNA stand.

I) predict which of the liquids would cause the largest decrease in mass of potato stick
oksian1 [2.3K]

Answer:

1 mol per dm3 sodium chloride solution

Explanation:

The liquid that would cause the largest decrease in the mass of the potato stick would be the one with  <u>1 mole per dm3 sodium chloride solution.</u>

<em>The water potential of a solution depends on the molarity of the solution, the higher the molarity, the lower the water potential and vice versa. Hence, a solution with higher molarity has the tendency to osmotically draw more water from the potato stick than a solution with lower molarity.</em>

Therefore, the potato stick will have the largest decrease in mass in 1 mol per dm3 sodium chloride when compared to the 0.5 and 0.1 mole per dm3 solutions.

Explanation:

Biodiversity refers to the diversity of biology or living organisms on Earth. The biodiversity is responsible for maintaining various biogeochemical on this planet.

The biodiversity has been drastically affected by the anthropogenic factors which has caused the deterioration of biodiversity.

The main anthropogenic factors are:

1. Habitat fragmentation: the human activities like construction of road passing through the habitat for organisms can lead to habitat fragmentation which could decrease the gene flow in the species.

2. Deforestation: the cutting of trees has led to the extinction of species.

3. Climate change : Global warming is the result of the industrial revolution initiated by humans in 19th century.

4. Exploitation of natural resources: the humans have continuously exploited human resources for their use.

5. Hunting of animals: The hunting of animals is one of the major factor for extinction of animals.
