Which factor listed below most likely results in the loss of genetic variation from small populations?

Physics
1 answer:
Snezhnost [94]3 years ago
8 0

The correct choice is genetic drift.

genetic drift is known as the variation in alleles number within a population and it mainly happens in small population where chances of losing an alleles are larger. it is common effect observed when significant number in a population die or when there is significant reduction in birth. hence genetic drift results in loss of genetic variation

Two small plastic spheres each have a mass of 1.1 g and a charge of -50.0 nC . They are placed 2.1 cm apart (center to center).
Solnce55 [7]

Answer:

Part a)

F = 0.051 N

Part b)

Both spheres will follow Newton's III law of action reaction force so both sphere will have same force of equal magnitude.

Explanation:

Part a)

Electrostatic force between two charged spherical balls is given as

F = \frac{kq_1q_2}{r^2}

here we will have

q_1 = q_2 = 50 nC

here the distance between the center of two balls is given as

r = 2.1 cm = 0.021 m

now we will have

F = \frac{(9\times 10^9)(50 \times 10^{-9})(50 \times 10^{-9})}{0.021^2}

F = 0.051 N

Part b)

Both spheres will follow Newton's III law of action reaction force so both sphere will have same force of equal magnitude.

Which air mass provides the moisture that produces the clouds and precipitation?
Andreas93 [3]
The MT is the air mass that provides the moisture that produces the clouds and precipitation. An air mass is a volume of air that is defined by its temperature and water vapor or moisture content .  MT is the abbreviation of marine time air mass. Air masses can control the weather for a relatively long time period from a period of days, to months, Most weather occurs along the periphery of these air masses at boundaries called fronts.

A soldier throws a grenade horizontally from the top of a cliff. Which of the following curves best describes the path taken by
Natasha_Volkova [10]

Answer:

4. Parabola

Explanation:

The motion of the flight of the grenade is a projectile motion, it's shape is best illustrated using a parabolic diagram.

It's not a circle as the path is not totally round.

It's not an ellipse as the path of motion is not a a completely bounded shape.

Its not a hyperbola as a hyperbola is an open curve with two branches.

Its a parabolic shape because a parabola has just one branch

an 80kg mountaineer climbs a 3000m mountain in 10h. What is the average power output during the climb
inn [45]

Answer:

70 W

Explanation:

Power = work / time

P = mgh / t

P = (80 kg) (9.8 m/s²) (3000 m) / (36000 s)

P = 65.3 W

Rounding to one significant figure, the average power output is 70 W.
