Decomposers because they decompose dead organisms, which releases the carbon.
Answer:
The correct answer is - 25600 bacteria.
Explanation:
Bacteria can divide and produce double their population very quickly. As mentioned in the question bacteria multiply every 15 minutes to their double number. Finding the number of bacteria after 2 hours is simple mathematics. Two hours means 120 minutes and dividing it to 15. The result will be 8 which mean the bacteria double their colony 8 time so,
100×2 to the power 8 = 100 (initial number of bacteria)×2×2×2×2×2×2×2×2= 25600
Thus, the correct answer is option- 25600 bacteria.
If you compare the original DNA with the mutated DNA, the first C got “substituted” by an A after the mutation.
So the answer is (C) substitution.
Answer:
Normal Gene: AUC AUA GGA AAA UAC
Mutated Gene: AUC ACA GGA AAU UAC
Explanation:
The transcription takes place in the nucleus. This process involve copying of DNA sequence into mRNA (messenger RNA) sequence. mRNA too consists of 4 nucleotides except the fact that in mRNA the thymine (T) is replaced by uracil (U). This involves the following steps:
- Unwinding of DNA
- Binding of RNA polymerase to the unwinded DNA.
- Synthesis of RNA commonly mRNA
- RNA elongation
- Stop codon (UAA, UAG, UGA) initiating termination of synthesis of RNA
