Mannitol salt agar (MSA) only allows the growth of halophiles. Among the halophiles, mannitol fermenters release acid that turns the pH indicator yellow; mannitol nonfermenters leave the medium red. Onto MSA you inoculate a halophilic mannitol fermenter, a nonhalophilic mannitol fermenter, and a halophilic mannitol nonfermenter. Thus, the medium is acting as a __________ medium.

Answers

Mannitol salt agar can act as both a selective and differentiating medium. A selective medium is one in which inhibits the growth of a particular organism, and allows others to thrive in said conditions. In this case, MSA favors halophilic organisms. MSA is also a differentiating medium because of the mannitol content. Mannitol is a sugar and mannitol fermenters, like s. saprophyticus, use mannitol and release acid as a byproduct. The pH indicator within the agar changes from red to yellow.

Single celled eukaryotes are considered some of the most complex
cells on earth. Why would scientists believe that single celled
organisms(eukaryotes) are more complex than multi celled
organisms?

Answers

Answer:

Eukaryotic cells are more complex than prokaryotes, and the DNA is linear and found within a nucleus. Eukaryotic cells boast their own personal "power plants", called mitochondria.The complex eukaryotic cell ushered in a whole new era for life on Earth, because these cells evolved into multicellular organisms.

Explanation:

Answer:

The ability to maintain different environments inside a single cell allows eukaryotic cells to carry out complex metabolic reactions that prokaryotes cannot. In fact, it's a big part of the reason why eukaryotic cells can grow to be many times larger than prokaryotic ones.

:-

One theory that may explain how eukaryotes became so complex is the endosymbiotic theory. This theory proposes that organelles like mitochondria and chloroplasts were once free-living prokaryotic cells that began to live within a larger host cell.

Answer:

A process common to all living organisms, whether aerobic or anaerobic, is glycolysis as part of the metabolism of all living organisms.

Glycolysis is the universally distributed metabolic pathway in all organisms and cells, by means of which a glucose molecule is degraded to two pyruvate molecules, in addition to producing energy in the form of ATP and NADH.

Specifically, ATP is the only high-energy phosphate that is formed primarily from the energy gain of the cell through oxidative processes (aerobic) or glycolysis (aerobic or anaerobic).

Glycolytic enzymes are located in the cytoplasm, near the contractile filaments, therefore, the ATP produced by the glycolytic pathway is formed near the place where it is used.

Phases:

Preparatory: Four reactions: two are phosphorylation and consume 2 ATP per glucose molecule.

The breakdown of hexose produces 2 trioses, which end in 2 molecules of glyceraldehyde-3-P. .

Oxidation of glyceraldehyde-3-phosphate (x 2) to pyruvate (x 2) and coupled formation of ATP in 2 of the reactions, in total 4 ATP and 2 NADH are formed.

In aerobics glycolysis consists of extracting energy from organic molecules from the oxidation of carbon by oxygen.

In anaerobic glycolysis the element used to achieve oxidation is not oxygen but sulfate or nitrate.

Therefore, we can conclude that a process common to all living organisms, whether aerobic or anaerobic, is glycolysis as part of the metabolism of all living organisms.

What is the function of enzymes in a living system?

Enzymes speed up metabolic reactions necessary for life. Without them, certain vital processes would not take place and the body would be unable to function.

Difference enzymes work better under different conditions. Where in a human body might it be beneficial to have enzymes work in very acidic environments?

In areas, like the stomach, that have a pH of two would benefit by having enzymes that function well in acidic environments. An example of such an enzyme is pepsin.

There is a large amount of catalase found in a human liver. Does the liver break down more hydrogen peroxide in the summer or winter? Explain your answer.

More hydrogen peroxide will be broken down in the summer…show more content…

Potassium permanganate - used to titrate and determine the amount of decomposed hydrogen peroxide.  

Sulfuric acid - was used to stop the reaction with catalase and hydrogen peroxide.  It denatured the enzyme (catalase) and halted the reaction so the amount of hydrogen peroxide decomposed could be measured.  

Before performing part D of the experiment, why was it necessary to establish a baseline?

The baseline is a control and shows the amount of decomposed hydrogen peroxide in the initial sample.  

You may have observed the reaction of naturally occurring catalase in tissue from either liver or potato. Design an experiment to determine if the amount of catalase varies from tissue to tissue (e.g. 200 g of the liver compared to 200 g of potato).  

Put the 100 g of potato in 1 petri dish and 100 g of the liver in another petri dish. Then put equal amounts of hydrogen peroxide for an equal period of time in both dishes. Drain the dishes and titrate them with potassium permanganate simultaneously. The numbers can now be compared using the steps in the sample calculation above in the lab report. In order to compare perform a potassium permanganate titration on pure hydrogen peroxide.  

Of the thousands of enzymes known, there is a family of enzymes called proteases that catalyze a reaction of breaking down proteins. What do you think would happen if you added a protease to your sample of catalase before proceeding with your experiment?  

The catalase would be broken

Answer:

Decodes the sequence of bases on the mRNA and then creates specifc proteins

Explanation:

Decodes the sequence of bases on the mRNA and then creates specific proteins. Therefore, option (A) is correct.

Ribosomes in eukaryotic cells are responsible for protein synthesis, a crucial process in which they decode the genetic information carried by mRNA molecules. Ribosomes read the mRNA sequence and use it as a template to assemble amino acids in the correct order, forming a polypeptide chain that folds into a functional protein. This process, called translation, occurs in two main subunits of the ribosome, which come together on the mRNA strand.

Ribosomes ensure accurate protein synthesis by matching each mRNA codon with the appropriate amino acid, guided by transfer RNA (tRNA) molecules. Ultimately, ribosomes play a central role in translating genetic information from DNA to create a wide variety of proteins that perform diverse functions within the cell and organism, making them essential components of cellular machinery. Therefore, option (A) is correct.

It's y

The cell Y is transitioning from metaphase to anaphase.

What is metaphase?

The chromosomes are at their second-most compacted and coiled state during the mitotic stage of the eukaryotic cell cycle, known as metaphase. These chromosomes, which contain genetic material, align in the cell's equator before being divided into the two daughter cells.

A phase of cell division known as "metaphase" (mitosis or meiosis). Individual chromosomes are typically dispersed throughout the cell nucleus. During metaphase, the cell's nucleus disintegrates and the chromosomes condense and migrate toward one another, aligning in the middle of the dividing cell.

The duplicate genetic material existing in a parent cell's nucleus is divided into two identical daughter cells during the third stage of mitosis, known as metaphase.
