Approximately how many mutations occur naturally in DNA per 10,000 bases?
A. 2
B. 2000
C. 200
D. 20
Explanation:
Modern methods indicate that the mutation rate is roughly one to two mutation per 10,000 genes per generation.
In human cells, approximately TWO (2) MUTATIONS occur naturally in DNA per 10,000 bases (Option A is correct).
The mutation rate (u) refers to the occurrence of new mutations in a given nucleotide sequence over time.In human cells, the mutation rate is approximately 10⁻⁴ per generation.Therefore, in a DNA sequence that has 10,000 base pairs of length, this value is equal to 2 mutations per generation (u = 2 / 10,000 = 10⁻⁴).In conclusion, approximately 2 MUTATIONS occur naturally in DNA per 10,000 bases (Option A is correct).

In the Avery, MacLeod, and McCarty experiment, the transforming extract from virulent bacteria was treated with DNase, RNase, or protease before being mixed with nonvirulent bacteria. The appropriate control for this experiment is to treat the transforming extract from heat-killed virulent bacteria with:
Answer:
Nothing
Explanation:
A. Control variables generally entail little or no system change. To see if the method worked, the researchers required a positive control in which the heat-killed virulent bacteria invariably transformed the non-virulent microorganisms. This positive control involves adding "nothing" to both the heat-killed virulent bacteria before mixing them with the non-virulent bacteria.

Why is The sun is the ultimate source of energy
for all living organisms.'
Answer:
"Sun is the ultimate energy source for all living organisms."
✴This is because plants need sunlight to make food through photosynthesis. This food is consumed by the animals and human-beings. Carnivores indirectly depend on plants for their food. So, if Sun is not there there will be no life on earth.
✴Secondly, sunlight is a good source of Vitamin-D.
Vitamin D is essential for strong bones, because it helps the body use calcium from the diet. Traditionally, vitamin D deficiency has been associated with rickets, a disease in which the bone tissue doesn't properly mineralize, leading to soft bones and skeletal deformities. So if sunlight is not there it can result in loss of Vitamin-D which can cause deficiency diseases.
✴If sunlight is not there there will be no day on Earth. Light will not reach our Earth. Every time there will be only darkness.
