Answer:
d. has acquired naked DNA from the environment
Explanation:
<em>Bacterial transformation is a process whereby a living bacterium takes up pieces of DNA from the environment and the foreign DNA becomes incorporated into the genome of the bacterium thereby 'transforming' it genetically. </em>
A transformed bacterium does not necessarily die within 48 hours, all other factors being considered.
Transformation does not hinder a bacterium from forming conjugation pilus.
Transformation does not always make a bacterium to be lethal to mouse. It depends on the gene present in the foreign DNA.
The correct option is d.
Here we would be using Hardy Weinberg equation for the calculation of allele and genotypic frequencies.
Dwarf genotype frequency = 
= 25% = 0.25
Frequency of allele t = q = 
= 
= 0.5
According to the equation,
p + q = 1
p = 1 - 0.5 = 0.5
Now, the frequency of heterozygous tall plants would be-
2pq = 2 * 0.5 * 0.5 = 0.5 or <u>50% heterozygous tall plants</u>.
Combustion occurs when the fuel is burned inside the engine to fuel the race car.
For question 3, it would not leak through the whole sandwich because the cell membrane is thick
The answer is 10 NADH.
For each glucose molecule that enters glycolysis, a total of 10 NADH are produced.
That is; during glycolysis 2 NADH are produced, while another two are produced in the conversion of pyruvic acid to acetyl-CoA, and in the Citric acid Cycle 6 NADH are produced, that makes a total of 10 NADH, which are then taken to the electron transport chain to produce ATP.
