Several scientific laboratories across the globe are involved in research concerning the origin of life on Earth. Which of these questions is currently the most problematic and would have the greatest impact on our understanding if we were able to answer it? How did RNA sequences come to carry the code for amino acid sequences? How could polymers involving lipids and/or proteins form membranes in aqueous environments? How can amino acids, simple sugars, and nucleotides be synthesized abiotically? How can RNA molecules act as templates for the synthesis of complementary RNA molecules? How can RNA molecules catalyze reactions?

Answer:

The answer is "Option C".

Explanation:

please find the correct question in the attached file.

Initially, its conversion of its RNA community through cDNA fragments is a technical step. In the RNA, therefore be placed in an NGS layout. Its sequence also utilizes either one-reading or one-end standard provided, in this connector were added for each end for fragments.  

  • RNA-seq analysis is mainly used to identify genetic changes, verbal behavior, and stitched analyses.
  • It is a useful waste material-product of sequence-based molecular imaging, although there are many drawbacks, like the low distinction of gene distribution.

The correct sequence for aerobic metabolic breakdown of glucose is
Luba_88 [7]

Answer:

a. glycolysis—preparatory reaction--cirtric acid cycle--electron transport system

Explanation:

  • Glycolysis is the first stage of cellular respiration that occurs in the cytoplasm of the cell. During glycolysis one 6 carbon glucose is converted into two molecules of 3 carbon pyruvic acid or pyruvate.
  • In the preparatory reaction, the pyruvate converted into a two-carbon molecule called acetyl CoA. In this reaction, a carbon dioxide molecule is released and a molecule of NADH is released.
  • The citric acid cycle begins with the reaction of the acetyl CoA with a four-carbon molecule in the mitochondrisl matrix. It goes through a cycle of reactions regenerating the four-carbon starting molecule. ATP, NADH and FADH₂ are produced.
  • The electron transport system is the terminal step of aerobic respiration that operates on the inner membrane of the mitochondria. Reduced coenzymes NADH and FADH₂ move along electron transport system release high-energy electrons and produce ATP.

Which of the following statements regarding energy systems is false? Select one: a. All systems are active at all times but one
Tasya [4]

Answer:

The correct answer is option C.  One system is switched on while the others are switched off is a false statement.

Explanation:

A biological energy system is a set of biochemical reactions known as metabolic processes that are concerned with the energy flow in an organism. In these processes energy converts into the ATP that is helpful in all types of cellular or muscular activity.

In the biological energy system, multiple or more than one system can be active at a time its not necessary that one system has to switch off while other is on.

Thus, the correct answer is option C. One system is switched on while the others are switched off is a false statement.
