Given that,
The speed of a wave, v = 200 m/s
Wavelength, 
We need to find the frequency of this wave. The relation between wavelength, frequency and the speed is given by :
So, the frequency of this wave is 100 Hz.
Answer:during this phase, the cell makes final preparations to divide. For example, it makes additional proteins and organelles. This phase is sometimes referred to as Gap 2.
Explanation:
Urbanization is defined as “the process of making an area more urban” or an increase in the amount of people living in towns or cities. Industrialization is defined as “the development of industries in a country or region on a wide scale” meaning a strong military with modern weapons, factories to create things, modern cars and boats etc. Urbanization and industrialization put a strain on the environment because of carbon gases emitted, effectively warming the earth up, destruction of trees which lowers our overall oxygen available, destruction of animal homes which will kill animals or cause unwanted interactions between humans and animals, and the pollution of natural resources such as local ponds, streams or the ocean.
Answer:
C) The smaller population will be more affected than will the larger population, because the smaller population has less genetic variation than the larger population has.
Explanation:
Genetic variations are present in the natural populations. Some of the genetic traits become adaptive under the changed environmental conditions and allow the individuals carrying them to survive and reproduce. In this way, the genetic variations help to maintain a population.
Therefore, a larger population of a squirrel species with more genetic variations will have less intense impacts of a disturbance/natural calamity and/disease. On the other hand, a smaller population of the same species with a lesser number of squirrels has fewer genetic variations. This population is more likely to be affected in a negative way by a disturbance such as pathogen.
