Answer: The correct answer is-
C. Crude oil is found below natural gas reservoirs.
Crude oil is a unrefined form of petroleum. Natural gas and crude oil both are nonrenewable sources of energy that are formed by remains of plants and animals that died millions of years back.
Natural gas is lighter as compared to crude oil. So natural gas has lower density as compared to crude oil. Due to this, crude oil is found below the natural gas reservoirs.
Thus, option C) is the right answer.
B. Tailbone of a human
C. Tail of a monkey
D. Flower of a plant
Answer: Tailbone of human
Explanation: The organs in the human body that are of no use now. These structures have lost their original functions in the body of the organism.
Although the vestigial organs have lost their original functions but it can develop new functions over time.
Example: Tailbone of humans, wisdom teeth are no longer used in human beings.
RNA or Ribonucleic acid is a molecule similar to DNA. It is single-stranded, has nitrogenous base pairs, and a sugar molecule. The RNA can be categorized into mRNA, tRNA, and rRNA.
The correct sequence of nucleotides in the tRNA will be:
U - U - A
In the nucleotide sequencing, the nitrogenous compounds present in the RNA are adenine, guanine, cytosine, and uracil instead of thymine.
The mRNA is a single messenger molecule, which is made from the transcription of DNA molecule. The further process involves the translation in which ribosomes play a crucial role.
In translation, the polypeptide is synthesized by the information delivered by the mRNA. The information in the mRNA is read in the form of a group of three nucleotides, known as a codon.
The codon is then read by the corresponding anticodon region of the tRNA molecule. It makes the set of the anticodon, which is complementary to the codon.
For instance, the mRNA containing the base pairing of A-A-U, the complementary sequence made by tRNA will be U - U - A.
Therefore, the correct answer is U - U - A.
To know more about mRNA and tRNA, refer to the following link:
Answer:
U-U-A
Explanation:
A mRNA molecule is formed as a result of transcription, which then proceeds to the ribosomes in the cytoplasm to undergo translation. Translation is the process whereby an amino acid sequence (protein) is synthesized using the information in the mRNA molecule/sequence. The mRNA sequence is read in a group of three nucleotide bases called CODON. Each codon specifies an amino acid.
This codon is read by another RNA molecule in the ribosome called tRNA (transfer RNA). tRNA contains another set of three nucleotides called ANTICODON, which is complementary to the CODON and responsible for reading the codon in order to carry the corresponding amino acid to the growing sequence.
According to this question, a portion of a messenger RNA molecule contains the base sequence A-A-U, the complementary anticodon sequence of the tRNA would be U-U-A.
Answer:
B.) Radiometric dating
Explanation:
Radiometric daiting is the ONLY answer to find the ABSOLUTE (not relative) age of a rock or fossil.
Community Two
They both have the same species diversity
There is not enough information to determine species diversity
