At the Earth's surface, rocks usually break quite quickly, but deeper in the crust, where temperatures and pressures are higher, rocks are more likely to deform plastically. Sudden stress, such as a hit with a hammer, is more likely to make a rock break. Stress applied over time often leads to plastic deformation. Hope this helps. ヅ
2) Cross-fertilization makes for more variation in the traits of plants, giving them immunities and resistances to weather, pests, and disease.
Answer:
The given blank can be filled with minimum viable population.
Explanation:
The MVP or the minimum viable population refers to the lowest number of individuals or the minimum density of the population of a species that can thrive in a specific region. The term is generally used in the fields of ecology, biology, and conservation biology.
The minimum viable population refers to the smallest probable size at which the population can prevail without encountering extinction due to demographic or natural disasters, genetic, or environmental stochasticity. Generally, MVP is utilized to signify towards a wild population, however, it can also be utilized for ex-situ conservation.
