Answer: A. the gravitational pull of the Sun

The sun is providing a centripetal force pulling the earth inward toward the sun. At the same time, the inertia of the earth is making it want to move forward in a straight line. The two forces work together to create the net effect of the earth orbiting around the sun. Other planets, moons, asteroids, and celestial objects exert gravitational forces on the earth as well, but nowhere near the amount of what the sun does.

Answer:

Bright white fur 3/4

Black fur 3/16

brown fur 1/16

Explanation:

From the Punnet's square analysis (see the attached image);

A_B_ 9/16
A_bb 3/16
aaB_ 3/16
aabb 1/16

A_B_ and A_bb will always give offsprings with bright white fur since allele A always mask the effect of B.

aaB_ will always give offsprings with black fur since allele a does not produce any protein.

aabb will give offsprings with brown fur since b codes for brown fur colour.

Hence, the phenotypic ratio of the offspring will be;

Bright white fur 3/4

Black fur 3/16

brown fur 1/16

galina1969 [7]

Answer:

option 4, y=1/4x+16

Explanation:

to solve this you must find the slope and the y intercept.

slope is rise/run, and equal to 2/8 or 1/4

then, the find the y intercept, find where the line crosses the y axis. Here it is 16.

finally you plug these answers into the slope intercept form, y=mx+b. In this form, m= slope, x=days, and b= y intercept.

after you plug in your answers you are left with y=1/4x+16.
