<u>Answer:</u>
The series dilution method is the step wise dilution technique where the dilution factors remain constant in each step.
The advantages of using the series of dilution method over simple dilution are stated below:
<em>a) Aids in reduction of a dense culture of cells to a more usable concentration.</em>
<em>b) In every step of dilution the specific amount of bacteria is removed. </em>
<em>c) Helps in the estimation of concentration of an unknown sample.</em>
<em>This sums up the advantage of using the series dilution technique.</em>
Answer:
A purine always forms a complementary base pair with a pyrimidine.
Explanation:
Purine bases such as Adenine pair specifically with Thymine , a pyrimidine base forming two bonds; just as Guanine pair specifically with Cytosine forming three bonds.
This specific base pairing are complimentary in nature and grants stability to the DNA.
False as there can be negative stimuli as well
Answer:
The chemical formular of amylose is( C6H10O5)n, Where the value of n= ranges from 300- 3000.These element are held together by alpha 1-4 glycosidic bonds in starch molecule( which contains amylose and amylopectin.) Both molecules are the chemical build up of starch.
Since water molecules are formed from the combination of OH and H atoms from each of the glucose molecule, with each of the glucose molecules either given out OH, H, OH, H atoms, as there are 4 glucose molecules, and 3 water molecules can be formed from 4-glucose molecule, Hence 3 water molecules will be liberated during condensation.

I believe it’s called Animal agriculture
