10) Which of the following describes a metabolic consequence of a shortage ofoxygen in muscle cells?
о
(A) An increase in blood pH due to the accumulation of lactic acid
O
(B) NO ATP production due to the absence of substrate-level phosphorylation
о
(C) A buildup of lactic acid in the muscle tissue due to fermentation
O (D) A decrease in the oxidation of fatty acids due to a shortage of ATP

Answers

Answer 1
Answer:

The statement 'a buildup of lactic acid in the muscle tissue due to fermentation' describes a metabolic consequence of a shortage of oxygen in muscle cells (Option C).

  • Aerobic cells normally produce energy by cellular respiration.

  • Cellular respiration is a process by which aerobic cells produce energy in the form of ATP by using the energy stored in the bonds of foods (e.g., glucose) and oxygen.

  • Acid lactic fermentation is a process by which muscle cells can produce ATP in anaerobic conditions.

  • This process (acid lactic fermentation) is less efficient than cellular respiration in terms of production of ATP per molecule of glucose, but it is faster.

In conclusion, the statement 'a buildup of lactic acid in the muscle tissue due to fermentation' describes a metabolic consequence of a shortage of oxygen in muscle cells (Option C).

Answer 2
Answer:

Answer:

The correct answer is - C) a buildup of lactic acid in the muscle tissue due to fermentation.

Explanation:

In absence of enough oxygen for the muscle cells to perform the aerobic pathway to breakdown pyruvate for energy, the body starts producing lactic acid to convert glucose into energy.

This process is known as fermentation which can produce lactic acid and build it in muscle cells. There are some negative effects of fermentation and buildup of lactic acid in muscle cells such as cramps, pain, and fatigue in the muscles.

It is possible to divide the evaluation of art into four simple steps. You can use these procedures to assess any work of art you're interested in buying or investing in.

What is evaluating art?

It is crucial to take into account the technical aspects of a work of art while judging it. How effectively an artist conveyed their intended message might depend on a variety of factors, including the media they chose, their brushstrokes, and their color scheme.

Remember that your unique reaction should reflect your own preferences and taste. Never listen to advice from other people about what you should or shouldn't like. Follow your gut and do what you think is best for you.

Why are DNA and rna important for cells

Answers

Answer:

They constitute the genetic material of living beings and act in the formation of proteins.

Explanation:

Both DNA and RNA are extremely important for life: they constitute the genetic material of all living beings. In the case of eukaryotic organisms, nucleic acids are present in the nuclei of cells, while in prokaryotic organisms (which have no nucleus surrounded by a membrane), the genetic material is dispersed in the cytoplasm. In addition, DNA and RNA are extremely important for the formation of proteins that will command all the functions of our body.

Bleaching is caused by the addition of bleach containing fertilizers that enter marine systems through runoff. True False

Answers

The given statement is False

Bleach such as chlorine when mixed in fertilizers acts as a killing agent for plants .The bleach runoff is not affected by the fertilizers containing bleach as they do not kill the Aquatic flora. Marine bleaching is caused due to high temperature of water not because of the fertilizers. In marine bleaching the coral will expel algae when the temperature of water is high. These results in discoloration of corals making them white and they can survive in this condition. This proves that the bleaching inside the marine system is because of high temperature not because of runoff.

false because bleach is not used in fertlizers

Carol and Sam were using the microscope in science class. They used a dropper to put some pond water on their microscope slide. This is what they saw. "That is something living," said Sam. "I don't think so," said Carol. What do you think? Explain.

Answers

Answer:

Explanation:

I think Sam is right because pond water can be full of impurities which can include many microorganisms such fungi, bacteria, protozoa, etc. For example, there is high possibility that the pond water sample collected by Sam and Carol would contain traces of blue-green algae which is also a living organism as it uses sunlight to prepare its own food.

Sam was actually correct. Pond water usually contains microrganisms like bacteria, viruses, and parasites. This is also why people do not drink pond water without getting rid of the impurities.

Nucleotides are the basic unit of which macromolecules?

Answers

Answer:

Nucleic acid

Explanation:

Nucleotides are the basic unit of Nucleic acid

A nucleotide consists of three groups –  

a) 5-carbon sugar (ribose or deoxyribose)

b) a nitrogen-rich base   - There are four nitrogen rich base namely cytosine (C), guanine (G), adenine (A), thymine (T)

c) and a phosphate group

The nucleotides are the repeating units of a nucleic acid and  therefore a nucleic acid can be considered as polymer while a nucleotide becomes its monomer unit.

Nucleotides are the basic unit of the macromolecules, nucleic acid. Nucleic acids are the deoxyribonucleic acid (DNA) and the ribonucleic acid (RNA.) These nucleic acids are large biomolecules that are far as known, is responsible for all forms of life.
