Maintaining the genetic diversity is long term solution which help to maintain polar bear population.
Explanation:
Polar bear from Norwegian way bears are genetically unique. These bears are only who survive in the world. they have lack genetic diversity so it is possible to they stay healthy and somehow survive in worst condition.
The climate and condition of Norwegian is way better so it is necessary to relocate the other polar bear. The other important thing is to ensure about their food. Polar bear mainly eat seal but due to the melting of ice they are unable to get proper food.
A cell membrane pump helps human cells to maintain a relatively constant sodium and potassium concentration.
<u>Option: A</u>
<u>Explanation:</u>
Sodium potassium pump is a plasma membrane protein that utilizes energy ATP — Triphosphate Adenosine turning into ADP — Adenosine Diphosphate to deliver intracellular and extracellular sodium (NA+) and potassium (K+) ions sequentially. The purpose of this entire mechanism is to preserve cell equilibrium.
The extracellular medium has a greater concentration of Na while the K concentration of the intracellular fluid is lower. Proteins trap sodium ions in the cytoplasm and pump them out from the cells to preserve cell stability while preserving concentrations. Within the cells proteins inject potassium ions into the cell.
The numbers 3 and 4 means that there are 3 Nitrogen atoms, and 12 Hydrogen atoms in the chemical formular (3NH4). The 3 coefficient in front of the compound applies to all of the elements while the 4 applies to only hydrogen (H). This means that the compound contains 3 Nitrogen atoms and 12 (4 multiplied by 3) Hydrogen atoms.
In incomplete dominance, heterozygous<span> phenotype is intermediate between two homozygous phenotypes. In this case, the symbols for alleles are capital letters. For example, allele A is responsible for red color of a flower, allele B is responsible for white color of the flower. Red flower plants have AA genotype, and white flower plants have BB genotype. By crossing plants with red flowers and white flowers, due to incomplete variance, the offspring will be heterozygozs plants (AB) with neither red nor white flowers, but pink flowers. Pink flowers have intermediate color between red and white flowers.</span>
