Natural selection also means survival of the fittest. This is where organisms who are better adapted to their environment survive and produce more offspring compared to the ones who aren’t as adapted to their environment.
Most pictures used as the milky way are actually just pictures of other galaxies (such as Andromeda) that we just figure are similar enough to ours.

Answer:
135degrees
Explanation:
Given that a vector starts at the point (0.0) and ends at (3,-3)
y component value = -3
x component value = 3
angle of the displacement theta = arctan(y/x)
theta = arctan(-3/3)
theta = arctan (-1)
theta = -45degrees
Since tan is negative in the second quadrant
theta = 180 - 45
theta = 135degrees
Hence the angle of the displacement is 135degrees
Answer:
The found value of r is:
r = 94.7
Explanation:
We know that
cosθ = Base / Hypotenuse
θ is the always the angle between base and hypotenuse
In this right angles triangle, the angle θ is given 63°.
Which means that the Base is 43 and the hypotenuse is r
Base = 43
Hypotenuse = r
Substitute θ=63°, Base = 43 and hypotenuse = r in the formula of cosθ mentioned above:
cos 63° = 43/r
Rearrange
r = 43/cos63°
r = 43/0.454
r= 94.7
