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.
Answer:
D. Many amino acids are encoded by multiple codons. A gene mutation that encodes the same amino acid would have no observable effect on the cell or the organism
Explanation:
If gene mutation does not change code (gene still encodes for the same amino acid), the same protein with its function will be produced. This is called synonymous mutation.
Silent mutations might also occur when codon is altered to produce an amino acid with similar function as previous (e.g. leucine to isoleucine) so that the function of protein is not significantly changed.
Answer:
A. The habitat that an organism lives in
D. All of the above
Good luck on the test ;)
The answer is D, serving as a primary source of energy for the body.
Answer:
Answer: The correct answer is discovery of codons. Marshall Nirenberg and Heinrich Matthaei experimentally deciphered the first out of 64 codons present in our biological system. ... So, it helped in decoding the first codon out of 64.
