Ionic bond is a compound made up of a meta and a non-metal eg NaCl (sodium chloride)
covalent bond is made up of two non-metals eg H2O (water)
The answer is C, i just did it and got it right so you can trust this answer, i wrote so much because of the 20 character thing

This is an example of microevolution.
Microevolution represents a small change in the genetic structure of the population. These changes manifest through the change in the allele frequencies of genes like in the case of dung beetles.
The causes of microevolution are evolutionary mechanisms, natural selection, genetic drift, mutations and gene flow.
Answer:
mass doubled makes KE twice as large
velocity doubled makes KE 4 times as large
Explanation:
Try it with an example
m = 4
v = 8
KE = 1/2 m * v^2
KE = 1/2*4 * 8^2
KE = 1/2 * 4 * 64
KE = 128
Now double the mass
m = 8
v = 8
KE = 1/2 8 * 8^2
KE = 1/2 8 * 64
KE = 4 * 64
KE = 256 double what it started out as.
Now do it again.
m = 4 That was the original mass
v = 16
KE = 1/2 4 * 16^2
KE = 2 * 256
KE = 512
When the velocity is doubled the KE becomes 4 times as big.
4*128 = 512
Seasons are Winter, Spring, Summer And Fall. The Sun moving (orbiting earth) causes them. So in the winter, the sun is on the opposite side of the world, and that's why it is so cold. In the summer, the sun is facing straight at us. Other season's, the sun is kinda in between, if that is any help
