Which statement describes one way that RNA differs from DNA? One is a protein, and the other is a nucleic acid. They contain dif

ferent five-carbon sugars and a different nitrogenous base. They are both carbohydrates, but one is a polysaccharide. One provides energy, and the other carries genetic information.

Answer:

The correct statement is - they contain different five-carbon sugars and a different nitrogenous base.

Explanation:

DNA or deoxyribose nucleic acid and RNA or ribose nucleic acid both are nucleic acids almost similar structurally, however, there are few fundamental differences in them.

DNA has double-stranded nucleic acid while RNA has a single-stranded.

RNA has ribose pentose sugar while DNA has a deoxyribose sugar.

RNA nucleotides have a uracil nitrogen base while DNA has thymine.

Thus, the correct statement is that they contain different five-carbon sugars and a different nitrogenous base.

Answer:

1)

  • frequencies of light-colored mice  ≅ 0.74
  • frequencies of dark-colored mice ≅ 0.26

2)

  • frequencies of light-colored mice ≅ 0.13
  • frequencies of dark-colored mice ≅ 0.87

3)

  • q² = 0.74
  • p² = 0.02
  • 2pq = 0.24      

4)

  • q² = 0.13
  • p² = 0.4
  • 2pq = 0.46

5)

The dark-colored fur seems to have the greatest overall selective advantage

6)

Dark lava, that changed the color of the substrate, from light to dark.

7)

Because to produce dark color, animals from the different regions suffered different mutations that drove them to have almost the same dark fur color. All of the animals are inhabiting dark substrate, which means that this environmental condition is favoring the same phenotype.

8)

To see if the mice population is evolving, you need to take a sample of animals per year, through many years, and analyze if it is changing or not. If the population is evolving, you will notice a change in the allelic and genotypic frequencies over the years, favoring one genotype or the other. If the population is not evolving, the frequencies will keep equal through the years, it will not change.

Explanation:

Due to technical problems, you will find the complete explanation in the attached files.

Stalactite.

<u>Stalactite:</u>

  • Often, stalagmites develop up from the cave floor, whereas stalagmites typically grow down from the cave roof.
  • It's simple to distinguish between the two since stalagmites have a "G" for ground and stalactites have a "T" for top.
  • Typically made of calcium carbonate, stalagmites can also be made of lava, mud, peat, pitch, sand, sinter, and amber.
  • A single drop of water rich in minerals is the origin of all limestone stalactites.
  • The smallest ring of calcite is left behind by the falling water drop.
  • Another calcite ring is left behind with each new drop of water that develops and drops.
