Answer:
Directional selection; stabilizing selection
Explanation:
- The stabilizing selection is a result of the decrease of the population and causes genetic variation due to the natural selection.
- The directional selection of the genetic variation shifts to a new phenotype and on exposure to the environmental changes and both of these can lead to the natural selection and contribute to the variation of the population.
Answer:
hey
Explanation:
sorry dont know the answers but hi
The Founding Fathers made an appropriate choice when they selected the bald eagle as the emblem of the nation. The fierce beauty and proud independence of this great bird aptly symbolizes the strength and freedom of America. The bald eagle is a bird of prey found in North America. A sea eagle, it has two known subspecies and forms a species pair with the white-tailed eagle. Its range includes most of Canada and Alaska, all of the contiguous United States, and northern Mexico.
Answer:
An explosion is a rapid expansion in volume associated with an extremely vigorous outward release of energy, usually with the generation of high temperatures and release of high-pressure gases.

Answer:
25v²
Explanation:
The kinetic energy in joules of a 50-kilogram runner running at v meters per second is modeled by the equation
Solution:
Kinetic energy is the energy of a body due to its motion. The kinetic energy of a body is maintained until there is a change in velocity. Kinetic energy can also be defined as the work done in accelerating a body from rest to a specified velocity. The SI unit is in Joules (J)
The formula for kinetic energy is:
K.E = (1/2)mv²
where m is the mass of the object and v is the velocity of the object.
Given that m = 50 kg and v = v, hence:
K.E = (1/2) * 50 * v² = 25v²
K.E = 25v²
