Answer:

tilt and orbit of the Earth combine in a way that the axis is inclined away from the sun

Explanation:

We have an equinox twice a year. The Spring and Fall equinox. An equinox occurs when the tilt of the Earth's axis and Earth's orbit around the sun combine in such a way that the axis is inclined away from the sun.

Answer:

An equinox is an event that takes place in Earth's orbit around the sun. ... The equinoxes and solstices are caused by Earth's tilt on its axis and ceaseless motion in orbit. You can think of an equinox as happening on the imaginary dome of our sky, or as an event that happens in Earth's orbit around the sun.

DNA polymerase has multiple mechanisms for editing and error correction whereas the capacity for error correction in RNA polymer
BigorU [14]

The given question is incomplete as the option are not provided however, the correct options are as follows:

Defective proteins are often degraded quickly, making their effects temporary.

Single amino acid substitutions caused by errors in mRNA transcription would not affect protein function.

Unlike DNA mutations, mRNA transcripts have short half-lives and are not inherited across many generations.

Degradation of defective proteins activates mRNA repair pathways RNA polymerases synthesize many transcripts per gene, so only a small fraction of RNA transcripts would have errors.

ch mRNA molecule is only translated once and then degraded

Answer:

The correct answer is - statements 1, 3, and 4.

Explanation:

DNA polymerase is the enzyme that is responsible for the production of the new DNA molecule and any mutation in this enzyme that will inhibit the DNA repair process which affects future generations.

RNA polymerase is an enzyme that is responsible for the transcription of DNA to mRNA and any error-prone mRNAs have chances of degradation. Error in DNA replication is from generation to generation as it is inherited

The process of transcription is quick.

Why does diversity increase as height above land increases​
wolverine [178]

Biodiversity rises with altitude initially before falling with height beyond that. Up until it reaches a diversity peak at about 1 300 to 1 800 m.

  • The biodiversity increases at higher geographical locations because There are more hiding locations. They are better for crop growth. They frequently include more than one kind of habitat.
  • As latitude or altitude change, so does biodiversity. As we descend from high to low elevations, the diversity increases (i.e., from poles to equator).
  • While the environment is harsh and plants have a brief growing season in the temperate region, tropical rain forests provide year-round growth-friendly circumstances.
  • This enables the emergence and expansion of several species. On a mountain, there is an initial increase in species diversity after which there is a decline in species variety as you go up in elevation.
  • At higher elevations, temperature drops and seasonal variations increase, which significantly diminishes.
