Which of the following explanations is true based upon the graph?

I. Lamb and mutton produce less protein per square meter than pig meat and poultry.
II. More land is needed for plants than combined beef to produce 100 grams of protein.
III . Meat production is less efficient than farming protein from fish and prawns.

A.) I only
B.) II only
C.) I and III only
D.) II and III only

Answers

Answer:

B.) II only

Explanation:

More land is needed for plants than combined beef to produce 100 grams of protein because plants produces very low amount of protein as compared to beef that produces large amount of protein. Beef is made up of protein so when we eat it, it provides large amount of protein while on the other hand, plant body is made up of other molecules and very little amount of proteins.

Translate the sequence of amino acids in sickle-cell hemoglobin into (use third valine)
a) mRNA base codes

b) tRNA base codes

c) DNA base codes

Answers

Answer:

Sickle cell hemoglobin occurs in the beta chain of hemoglobin due to point mutation in the sixth codon which changes from glutamic acid to valine which is hydrophobic that causes the change in the size of the RBC in a crescent shape.

The protein or amino acid chain of this condition is as follows:

Protein with Sickle Mutation: VAL HIS LEU THR PRO VAL GLU

which is translated from mRNA sequence

mRNA with Sickle Mutation: G U G C A C C U G A C U C C U G U G G A G

mRNA sequence is the complementary sequence or anticodons of the mRNA sequence RNA:

tRNA with Sickle Mutation: C A C G U G G A C U G A G G A C A C C U C

mRNA sequence is transcribed from the transcription strand of DNA sequence:

DNA with Sickle Mutation: C A C G T G G A C T G A G G A C A C C T C

In arthritis, there is deposition of urate crystals in joints. If you want to treat the arthritis by decreasing the concentration of circulating uric acid, what will you do with its mechanism in kidney?

Answers

Answer and explanation:

If I'd wanted to decrease the concentration of circulating uric acid by altering its mechanism in the kidney, I would administer a drug that would inhibit uric acid reabsorption and increase its excretion through urine.

Arthritis is a condition characterized by inflammation of the joints and can be caused by many diseases. When the cause of this arthritis is the deposition of urate crystals in the joint because of an increase in the concentration of circulating uric acid (hyperuricemia) we are most likely talking about gout, a painful disease that can deform the joints.

Hyperuricemia and gout have many risk factors associated with them, such as genetic predisposition, unhealthy diet, and suffering from other conditions like Diabetes.

Several medications are used in the treatment of the symptoms and the prevention of the worsening of this disease, but the one that is most frequently used to increase the excretion of uric acid is Probenecid. Probenecid blocks the kidney's OAT (organic anion transporter) that reabsorbs uric acid in the kidney tubules, thus enhancing its excretion and decreasing uric acid's blood concentration.

Which of the following statements is true? Which of the following statements is true? No archaea are capable of using CO2CO2 to oxidize H2H2, releasing methane. Prokaryotes have low levels of genetic diversity. Archaea and bacteria have identical membrane lipids. The cell walls of archaea lack peptidoglycan.

Answers

Answer:

The correct answer is - The cell walls of archaea lack peptidoglycan.

Explanation:

Archaea are the prokaryotes that are different from bacteria in various ways but the most important differences are the membrane lipids and the major component of the cell wall that lacks peptidoglycan found in the cell wall of bacteria.

These prokaryotes are able to use carbon dioxide to oxidize hydrogen, releasing methane. Archaea-like prokaryotes have a high level or complex genetic diversity.

What conclusions did Watson and Crick reach after reading Franklin’s report discussing the symmetry of DNA?

Answers

Answer:

They formed a revised model.

Explanation:

After seeing Franklin's x-ray images of DNA and her report on DNA's symmetry, Watson and Crick formed a revised model of DNA's structure i.e. a double helix with sugar-phosphate backbones that is running in opposite directions. Watson, Crick, Franklin, and Wilkins are co-discovered the double-helix structure of DNA, which formed a basis for modern biotechnology. Images taken by Franklin allowed James Watson and Francis Crick to create their two-strand, or double-helix, model.
