Answer:
because the membranes are selectively permeable.
Explanation:
Meaning it only allows certain ions to move across.
The two types of limiting factors are Density - dependent and Density independence. <span> Density-dependent limiting determinants depends on the community size; the comprehensive population, the consequential influence a density-dependent limiting agent will ought. Density-independent limiting determinant does not really depend on inhabitants dimension, alternatively they change all populations proportionately. </span>
Answer: The reason is because DNA polymerase which is the enzyme that catalyzes the synthesis of DNA has a 3'->5' exonuclease activity that double-checks each nucleotide after it is added.
Explanation: The 3'->5' exonuclease activity of DNA polymerase allows the enzyme to double-check and remove a newly added wrong nucleotide. It is highly specific for mismatched base pairs. When the DNA polymerase adds a wrong nucleotide to the growing strand, translocation of the enzyme to the position where the next nucleotide is to be added is halted, but the exonuclease activity of the DNA polymerase removes the incorrectly paired nucleotide so that replication can continue. The process of double-checking a newly added nucleotide and removal of any incorrectly paired nucleotide by the DNA polymerase is called proofreading.
Free of unknown diseases is the least likely reason that pigs have been chosen as donors for humans in the process of xenotransplantation.
Answer:
Fault zones cause Earthquakes
causes the shaking that is associated with earthquakes
Explanation:
An Earthquake takes place whenever the underground rocks break in the fault zone suddenly. While they break they release an energy that generates seismic waves causing the shake of the Earth ground.
While the rocks get rubbed against each other it sticks and creates pressure, this pressure breaks the rocks and Earthquake take place. The rocks break in the focus zone of the Earthquake and the shaking is caused by the fault zone.
