The RNA world hypothesis states that the earlier life-forms had relied only on RNA (Ribonucleic Acid) for the purpose of catalyzing the chemical reactions, and storing the genetic information. This hypothesis was proposed by Leslie Orgel, Carl Woese, and Francis Crick.
This hypothesis states that long before the living forms evolved to use DNA as the genetic storage material, the RNA molecules served the purpose of both storing the genetic information and carrying out catalysis, but because of its instability, DNA evolved.
Hence, the answer is RNA world hypothesis.
Answer:
Law of Dominance
Explanation:
The dominant trait dominates or prevents the expression of the recessive trait. Dominant trait and recessive trait are represented by a capital and a small letter respectively. A dominant trait like round is seed, for example is represented by letter R and a recessive trait like wrinkled seed is represented by small letter r.
Bacteria, since most gas is due to the breakdown of fats or carbohydrates by intestinal flora (normally dwelling bacterial cultures)
Answer:
20%
Explanation:
Given that:
Actual weight of 1 mL of water =. 1g
Average weight using :
TOOL A = 1.2
TOOL B = 1.5
Percentage Error of TOOL A:
(|approximate measurement - actual measurement| / actual measurement) * 100%
(|1.2 - 1| / 1) * 100%
(0.2 / 1) * 100%
0.2 * 100%
= 20%
They grow Hyphae instead.
