Answer:
Natural selection is a mechanism, or cause, of evolution.
Explanation:
Adaptations are physical or behavioral traits that make an organism better suited to its environment. Heritable variation comes from random mutations.
Answer: Got It!
<em>Explanation: </em>let s = speed at launch
v = 0 at top = s sin 63 - g t
so at top
t = s sin 63/g = .0909 s
h = 13.6 = s sin 63 t - 4.9 t^2
13.6 = .081s^2 - .0405 s^2
s^2 = 336
s = 18.3 m/s
0 0
Answer:
<h2>Uses of plane mirrors</h2>
They are used in periscopes, for signalling, in kaleidoscopes, to see round dangerous bends, in meters, as mirror tiles, in a sextant, in an overhead projector, an SLR camera, car wing mirrors, in microscopes and as reflecting number plates to mention only some!

The answer would be: c. High levels of dissolved oxygen
Oxygen is vital for most (aerobic) organism. Fish using oxygen that dissolved in the water so high level of dissolved oxygen will make the fish grow easier. Water with pH of 5 would be an acid water. Acid is corrosive and it can kill some organism that sensitive. High levels of fecal coliform mean the water contaminated with fecal material and must have a high level of bacteria.
Answer: The heating of the Earth's surface and atmosphere by the sun drives convection within the atmosphere and ocean. This convection produces winds and ocean currents. The greater the pressure differences between a low-pressure area and a high-pressure area, the stronger the winds.
