What is the essence of the catalase test?

Biology
1 answer:
garik1379 [7]2 years ago
8 0

Explanation:

Catalase test demonstrate the presence of an enzyme called catalase, that catalyses the release of oxygen from hydrogen peroxide. It is used to tell the difference between the non-catalase producing bacteria from those bacteria that produces an enzyme catalase. Catalase is produced by the bacteria that respire using oxygen. If an organism produces catalase, bubbles of oxygen are produced when hydrogen peroxide is added to it.

The transmission of genetic material from one generation to the next is necessary for the survival of a species. Which statement
scoundrel [369]

Answer:

The correct answer would be B) The complementary base pair rules.

DNA serves as the genetic material in most of the living organisms and is transmitted from parents to their offspring.

It is like blue print of the cell which contains all the necessary information required for the functioning and regulation of cell in the form of nucleotide sequences.

Generally, DNA consists of two strands which are complementary in nature i.e. purine base pair with its specific pyrimidine (adenine always base pair with thymine and guanine always base pair with cytosine).

This property of DNA is of utmost importance in the process of DNA replication as daughter DNA strand is formed on the basis of complementary base pair of the template strand.

It ensures that correct DNA sequence is produced for transmission to the offspring or daughter cell.

How does the Foucault Pendulum show that the Earth rotates?
egoroff_w [7]

The Foucault Pendulum show that the Earth rotates because the pendulum would swing so slowly that it would appear to change direction as the Earth moved away.

<h3>How does the Foucault pendulum work?</h3>

The Foucault pendulum was able to demonstrate experimentally that the Earth revolves around itself with an angular velocity Ω, in a period of 23 hours, 56 minutes and 4 seconds.

Thus, Foucault knew that the longer the string attached to the weight, the slower the swing of his pendulum. He could attach the string above to an almost frictionless pin, and if he used a very large weight, the pendulum would swing so slowly that it would appear to change direction as the Earth moved away.

Glucose labeled with 14C in C-3 and C-4 is completely converted to acetyl-CoA via glycolysis and the pyruvate dehydrogenase comp
Morgarella [4.7K]

Answer:

The correct answer is option d.

Explanation:

The production of Acetyl-CoA takes place by the dissociation of both carbohydrates and lipids in the process of glycolysis and beta-oxidation. It then moves into the TCA cycle in the mitochondria and combines with oxaloacetate to give rise to citrate.  

In the given case, no labeling will be found in the acetyl-CoA. The labeled C3 and C4 carbon of glucose signify the carboxyl carbon of pyruvate. In the succeeding reactions of the transformation of pyruvate to acetyl-CoA, the carboxyl carbon gets lost in the form of carbon dioxide. Thus, acetyl-CoA does not comprise any labeled C3 and C4 of glucose.
