Genetic drift is a random process that can lead to large changes in populations over a short period of time. Random drift is caused by recurring small population sizes, severe reductions in population size called "bottlenecks" and founder events where a new population starts from a small number of individuals.

Answer:

Small population size, reduction in the number of individuals in the population.

Explanation:

Genetic drift may be defined as the change in the gene frequency of population of due to the random sampling of the organisms. Genetic drift may result in loss of genetic variation in a population.

The main factor responsible for genetic drift is the small population size. Small population size has higher chances to undergo the random sampling. Sudden decrease in the size of population due to natural disturbances is also responsible for the phenomena of genetic drift.

How many contractions per minute were required for the paramecium to maintain a relatively stable internal solute concentration

Phoenix [80]

Answer:

abt 24 contraction per min is needed to maintain a relatively stable internal solute conc.

paramecium maintain its volume by preventing itself from shrinking by holding in as much water as it can.

When the water solute concentration is reduced, the number of vacuole contractions will increase. But when the water solute concentrations rise, the number of vacuole contraction will decrease.

When the number of vacuole contractions will increase, the water solute concentration is reduced. But when the water solute concentrations rise, the number of vacuole contraction will decrease. So it is cetris paribus, means when the one is increase the other one will decrease.
