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

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.

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.

PLEASE HURRY !!!!!!How does plate tectonics affect climate?
(Points : 1)
(a)increased earthquakes

(b) changing ocean circulation

(c) extinction of animals

(d) changing earth's position on its axis

Answers

The correct answer is - (b) changing ocean circulation.

The ocean currents are very important when it comes to the climate. The movement of the tectonic plates though, over time, is changing their patters. The changes appear because of the movement of the land masses, so there can be situations where the ocean currents are interrupted by a moving land mass, or more space to be opened up for an already existing ocean current with the moving away of a land mass of its path. Those movements and spaces in the water bodies are affecting the direction and the temperature of the ocean currents, and those changes will reflect on the climate on the regions that they are influencing.
at human scale by increased earthquakes and at the geological scale by changing ocean circulation
