Answer:Naturally occurring,inorganic substance.
Explanation:
Answer:
Radiation leads to mutations that causes genetic drift and decrease fitness.
Explanation:
Radiation is responsible for changing or altering the DNA sequence within a cell.
Radiation either causes mutation or it leads to cell death.
Most of the ionizing radiation causes mutation within the deep inside of our cells which eventually leads genetic drift which means change in the frequency of the allele in a population over time.
Beneficial mutation confer advantage to the organism. But in this case, the mutation is not beneficial and decreases the fitness of the rodent organisms.
Answer:
The correct answer is -
Thymine: 20%
Guanine: 30%
Cytosine: 30%
Explanation:
According to Chargaff's rule which states that the purine residues are equal to the pyrimidines residue in DNA sample which means A+G = T+C where A is adenine, G is guanine, C is cytosine and T is thymine. It is also known that A is always equal to T and C is equal to G.
So, A+G+T+C = 100
20+20+G+C
100-40 = G+C
60= G+C
as we know G is equal to C similarly A is equal to T
Thus, G = C= 30%
A= T= 20%
C because we are testing the effectiveness of Fertilizer X and Y and using no fertilizer can help determine if that would be better than using a fertilizer. Additionally, a control group of no fertilizer would be the third plant as that is considered normal for the experiment. Msg me for any more questions
Answer:
Claire's diagnosis may show the absence or a very small amount of proteolytic enzymes in her small intestine.
Explanation:
Claire's diagnosis may explain the slow digestion of proteins due to the absence or decrease of proteolytic enzymes in the small intestine. That's because these enzymes must be present in the small intestine in amounts suitable for the protein digestion process to be rapid, as a digestion process, through enzymes must be. This is because enzymes are responsible for speeding up the metabolic processes, if there is a lack of enzymes, the metabolic processes become slower.
