Which of the following is true of RNA compared to DNA?a. It lacks phosphate groups.
b. It is a single-stranded molecule.
c. Its nucleotides do not have sugars.
d. It contains four different nucleotides.

Answers

Answer 1
Answer: The correct answer is B. It is a single-stranded molecule. It does not lack phosphate group but rather has a different one so there's also 4 but they're a bit different. Unlike the DNA that is a double spiraling strand, the RNA is just a single strand that goes on and on. Although similar, it does completely different things from the DNA.
Answer 2
Answer:

Final answer:

RNA is a single-stranded molecule, in contrast to the double-stranded structure of DNA.

Explanation:

b. It is a single-stranded molecule.

RNA is a nucleic acid that is similar to DNA, but with a few key differences. One of these differences is that RNA is single-stranded, while DNA is double-stranded. This means that RNA is made up of only one chain of nucleotides, while DNA has two chains that are complementary to each other.

Other differences between RNA and DNA include:



  1. RNA contains the sugar ribose, while DNA contains the sugar deoxyribose.
  2. RNA uses the nitrogenous base uracil, while DNA uses thymine.
  3. RNA is typically shorter than DNA.

Plant cells have a _____ while animal cells do not. A. plasma membrane B. nucleus C. cell wall

Answers

The answer is C. cell wall. Plant cells have a cell wall while animal cells do not. Plant cells' cell wall is mostly made of cellulose, which is a polysaccharide.

Select all that apply. If you wanted to try and identify or classify archaea or eubacteria, you would _____-study their habitat
-study their genetic make-up
-study their shape and arrangement
-conduct Gram staining
-study how they gain energy and nutrients
-study how they move

Answers

If you wanted to try and identify or classify archaea or eubacteria, you would study their habitat, study their genetic make-up, study their shape and arrangement, conduct Gram staining, study how they gain energy and nutrients and study how they move. Archaea and eubacteria are genetically different; Archaea have more complex RNA polymerases that contain multiple polypeptides while eubacteria have simple RNA polymerases that contain four polypeptides. Archaea cell walls do not contain peptidoglycan while almost all bacteria cell walls contain peptidoglycan.
The right answer for the question that is being asked and shown above is that: "-study their habitat; -study their shape and arrangement
-conduct Gram staining; -study how they gain energy and nutrients; -study how they move
