Answer:
D. None of the above
Explanation:
<u>Reason that Drastic Change in weather may cause mass extinction</u>
Weather plays an important role in the survivability & the growth/diminish of the population. For example, animals that need large amounts/bodies of water (for example fishes), will not survive when the area is hit with a heat wave & drought, which would cause fishes to surface, and die.
<u>Reason that Geological change would play a large role in mass extinctions</u>
While the Geography is constantly changing, large abrupt changes would cause a upheaval and may upset the population, leading to a depletion of resources or even a sudden destruction of part/all of the population. For example, an earthquake may kill large amounts of animals, and the destruction of the greenery in the area may severely limit the amount of food/decrease the primary consumer's populations, leading to a starvation.

Answer:
2c. Jamestown Settlement and the "Starving Time"
Explanation:
The first joint-stock company to launch a lasting venture to the New World was the VIRGINIA COMPANY OF LONDON. The investors had one goal in mind: gold. They hoped to repeat the success of Spaniards who found gold in South America.
In 1607, 144 English men and boys established the JAMESTOWN colony, named after King James I.
The colonists were told that if they did not generate any wealth, financial support for their efforts would end. Many of the men spent their days vainly searching for gold.
As a consequence, the colonists spent little time farming. Food supplies dwindled. MALARIA and the harsh winter besieged the colonists, as well. After the first year, only 38 of the original 144 had survived.

An action potential will not occur unless the membrane potential AT THE VOLTAGE GATED SODIUM CHANNEL reaches a level called THRESHOLD.
An action potential refers to the change in the electrical potential which occurs as a result of the passage of impulses along the membrane of muscle cells or nerve cells. An action potential occurs when there is depolarization of the cell membrane to the threshold stage.
