Answer:
The presence of moisture is the independent variable.
The earthworm behavior is the dependent variable.
Explanation:
Answer: knowing that the number of adenine will be always equal to the number of thymine.
Explanation:On the basis of base pairing rule, the purine bases bonds with the pyrimidine bases. This takes place as the configurations of pyrimidine and purine bases permit formation of hydrogen bonding between the two.
The base pairing rule suggests that the pairing of adenine takes place only with thymine and pairing of guanine takes place only with cytosine. Two hydrogen bonds are produced between an adenine and thymine base pair, while three hydrogen bonds are produced between a guanine and cytosine base pair.
#1
- Ocean acidification is harmful for aquatic ecosystem
- This is being reason for death of many aquatic creatures
#2
CO_2 will form carbonic acid which is acidic in nature
- So it will decrease the pH
#3
PH stands for potential of Hydrogen .
- If pH is less than 7 it's acidic and if greater than 7 it's basic
1. The enzyme DNA helicase breaks the hydrogen bonds between bases on the two polynucleotide DNA strands. This makes the helix unwind to form two single strands.
2. Each original strand acts as a template for a new one. Complementary base pairing means that free DNA are attracted to their complimentary exposed bases on each original template strand; A with T; C with G.
3. The enzyme DNA polymerase joins the nucleotides of the new strand together via condensation reactions. Hydrogen bonds form between the bases on the original and new strands
