What's the difference between genetic drift and change due to natural selection?

Biology
1 answer:
JulijaS [17]3 years ago
4 0

Answer:

Genetic drift does not require the presence of variation.

Explanation:

Genetic drift is the random changes to the frequency of an allele in a given population.

Natural selection is the process whereby organisms that are well adapted to the conditions in an environment can survive and produce more offspring.

  • Genetic drift does not require variation to occur.
  • It usually occurs even when there is less to no variation.
  • Natural selection occurs when variation is very large.
  • A highly varied gene pool causes natural selection.

4vir4ik [10]

Answer:

Eating healthier foods

Explanation:

There are many things, such as social, behavioral, and biological factors, that can affect the way we feel about life. In the given scenario, we have Harriet, who has made some changes in her life that make her feel better. She made new friends and found guidance from community leaders, which can be defined as a social influence - an influence originating from interaction with other people. She also introduced a new behavior to her routine - writing about her daily achievements. This is healthy behavior, as she is reminding herself about the good things she has done and additionally motivating herself. The only change that can be described as a biological influence is the change in her diet - she started eating healthier foods. This directly affects her body and makes her feel generally better. It's true that there's a healthy mind in a healthy body.

Solute is the substance that dissolves

  • Solute is a minor component
  • Solvent is a major component
  • Solutions is a mixture where the solute is uniformly distributed in the solvent.
  • Solution  is homogeneous mixture that contains particles the size of a typical ion or small molecule.
  • The mass of the solute dissolved per unit volume of solvent is called Concentration
  • Solubility is The concentration of a saturated solution
  • Solutes lower the freezing point and raise the boiling point of a solvent.
  • Saturated Solution is a solution in which no more solid can be dissolved
  • Unsaturated Solution is solution in which more solid can be dissolved
  • Precipitate is a solid that crystallizes out of a saturated solution as it is cooled.

The sodium-potassium pump is involved in active transport that moves 3 sodium ions from the cell for every 2 potassium ions it m
Ugo [173]

Answer:

The sodium-potassium pump is an active transporter because it needs to move sodium and potassium ions against the concentration gradient.

Explanation:

You have to think of it as outside vs inside the cell.

Outside the cell, you have 5mM K and 150mM Na. Inside the cell, you have 100mM K and 10mM sodium. Without the transporter then the ions would go from greater concentration to lower concentration.  Energy keeps the ions going from the way they would naturally happen.
