If no carbon dioxide is present in your test tube it will be a black Color. If a medium amount of CO2 is present, your test tube will be a brown color. If a large amount of CO2 is present, your test tube will be white.
Carbon dioxide is an invisible gas plays a significant role by being one of the most effective green house gas.
Earth's atmosphere is made up of about 0.03% of Carbon dioxide (CO₂) and a small increase in this concentration can lead to an adverse effect, thereby causing global warming.
for example charcoal is a dark grayish colored product of carbon is obtained after the withdrawing the water and volatile components of organisms as well as plant materials.
Burning of charcoal produces carbon dioxide used for various purposes such as cooking fuel, industrial fuel, skin care as well as whitening of teeth.

b. news about a scientific discovery reaches the public sooner.
c. only the most exciting experiments are published.
d. a hypothesis is accepted without any supporting evidence.
Answer: A. A scientific paper is a reliable source of information.
Explanation:
A peer review is a kind of analysis of the research outcome by the people who generally exhibit the same competency as that of the author or researcher and knowledge for a particular subject or topic in which the research has been conducted. Such a process makes the research outcome more authentic and reliable. The author learns to improvise the research process and corrects the mistakes after the peer review.
Answer:
The correct answer is : A scientific paper is a reliable source of information.
The question is incomplete. The complete question is as follows;
Imagine you are following a particular tRNA, called tRNAQ, through the process of translation in a eukaryote. In what order does tRNAQ go through the steps listed below? (Note that some steps may be used more than once.)
1. The polypeptide is transferred to tRNAQ.
2. tRNAQ binds the A site of the ribosome.
3. tRNAQ binds the P site of the ribosome.
4. The ribosome shifts, with tRNAQ still bound.
5. tRNAQ binds the E site of the ribosome.
3, 4, 1, 4, 2, 4, 5
3, 1, 4, 2, 4, 5
2, 4, 1, 4, 2, 4, 5
5, 1, 4, 3, 4, 5
2, 1, 4, 3, 4, 5
Answer:
2, 1, 4, 3, 4, 5.
Explanation:
The translation process involves the different types of RNA, ribosome and different translation factors. This process results in the formation of the protein product from the RNA molecule.
The ribosome contains the three site known as A site (entry site), P site ( peptidyl site) and E (exit site). The tRNA Q must enter first to the A site and contain some initiation factors. tRNA Q contains the specific anti codon that are complementary to the codon present on the mRNA. The polypeptide is the attached to the tRNA Q. This allows the movement of ribosome over mRNA and tRNA Q will enter in P site. The ribosome shifting still occurs and then tRNA Q enter the E site and later exits from the ribosome.
Thus, the sequence is 2, 1, 4, 3, 4, 5.
