What type of mutation in nucleotide 4 would produce the same amino acid?

Most likely a silent mutation. Silent mutations are mutations in DNA that do not have an observable effect on the organism's phenotype because the same amino acid is produced regardless of the change in the nucleotide sequence by the mutation.

Microscopic plants called algae grow inside the top layer of sea ice in the Antarctic if enough sunlight reaches that layer of i
MrRa [10]

Answer:

The correct answer is: (A).

Explanation:

  • In the question, it is mentioned that the algae can grow under the conditions of "enough sunlight" and "enough nutrients".
  • Sunlight reaches the algae, by first falling on the surface made up of ice and snow and then refracting from there into the top layer of the ice where the algae grows.
  • However, the capability of both snow and ice to reflect sunlight is far more than that of refracting sunlight.
  • Therefore, the amount of light received by the algae is similar in absence or presence of the layer of snow on the top layer of ice.
  • However, on deposition of snow on the layer of the ice, the weight of the ice increases and it sinks below into sea water.
  • This allows more nutrient rich sea water to percolate into the ice and reach the algae.
  • The algae receive more nutrients from the sea water and hence is capable undergoing better metabolism and growth.
  • Hence, more algae are produced under such a situation.

Two planets with the same mass and atmospheric conditions orbit a single star. Planet A is closer to the star than Planet B. Whi
sveticcg [70]

Answer:

Planet B is expected to be cooler than Planet A.

Explanation:

In the given case, planet A is closer to the star than planet B. Their atmospheric conditions and mass is same so their surface temperature will depend on their distance from the star. Since planet A is closer, it will receive more radiation from the star. In turn it will be hotter to re-radiate that energy back to space. Hence, average surface temperature of planet B will be lower than planet A.
