Answer D. Because the DNA is different
Answer: the correct answer is (B) Whether others of the closely related group of plants also produce histidine in large quantities
Explanation:
This is a CAUSAL argument.
In a causal argument, A and B are observed together, and the CR concludes that A CAUSES B.
Premise = A and B are observed together:
A cultivated herb produces histidine and is able to grow in metal rich soils.
Conclusion = A causes B:
Histidine CAUSES the herb to be able to grow in metal rich soils.
One way to strengthen the conclusion that A causes B is give ANOTHER SUPPORTING EXAMPLE that links A to B.
Answer:
RNA contains an additional oxygen atom on the ribose sugar. (Ans. C)
Explanation:
RNA contains a sugar which is known as ribose, and which contains an extra group of hydroxyl (OH-) while DNA contains deoxyribose sugar.
RNA contains four nitrogenous bases cytosine, adenine, guanine, and uracil, while DNA contains cytosine, adenine, guanine, and thymine.
Double helix means two stranded structure like DNA, while RNA is single stranded.
DNA molecule is much longer polymer than RNA molecule.
Answer:
The correct answer is c. Bacteremia
Explanation:
Nosocomial infection is a hospital-acquired infection. Intravenous catheterization is majorly used in hospitals for therapeutic purposes like drug administration, blood sampling, etc.
These catheters are one of the major causes of nosocomial bacteremia in patients. Bacteremia is the condition in which bacteria is present in the blood.
So these catheter can be contaminated with bacteria which came from a patient and when they are used in another patient without proper sterilization they can transfer these bacteria to other patients blood which then cause nosocomial bacteremia.
