Biology

Marianna [84]3 years ago

Muzzle velocity is a vector quantity which means it has direction and magnitude. Generally speaking, any velocity is classified as a vector quantity, a value with direction and magnitude. Velocity is the rate of change of the location of the object moving and is specified by its direction and speed. Since muzzle velocity is a velocity then it would surely be a vector quantity. Muzzle velocity is the speed of a bullet as it is leaving a muzzle of a gun in a the direction where the gun is pointed. It would have a value ranging from about 120 m/s to 370 m/s in muskets to 1200 m/s for modern rifles.

Consider the data on cliff swallow mortality. Why is this an example of directional selection?Overall genetic variation decrease
Gala2k [10]

Answer:

The average trait value changed in one direction.(In this case, larger size)

Explanation:

In evolution a natural selection can be disruptive, directional or stabilizing

In stabilizing no extreme trait is favored hence provides intermediate values .

Disruptive selection both extreme traits are favored over the intermediate trait.

Directional, the enviroment will favor the survival of one trait hence a change in direction either towards the left or the right.

In the case of swallow cliff mortality, selection favored the larger size.
