the answer is true. please correct me if I'm wrong !,
but I hope this has helped you.
You would probably have to observe what your looking at. Look closely, do you see any cracks or crevices in the bones you are looking at? Do you see any indents or chipped pieces? Color, shape and size can also really help when observing a fossil. After close observation use resources and figure out what kind of fossil it is. Hope this helps!
The first scientific discovery is the epigenetic variation where it describes the deviation in the chemical tags that attach to DNA which affect how genes are read. Theses tags are called epigenetic markings that act as switches that control how genes can be read. Another essential discovery on human variation is the genetic variability, which measures the tendency of individual genotypes in a population to become different from one another. In addition, the variability of a trait is how much that characteristic tends to vary in response to environmental and hereditary influences.
1.) When a boy was skating, kinetic energy was high, and thermal energy was low.
2.) As the boy applied his brake pad, kinetic energy was decreasing and thermal energy was increasing.
3.) When the boy stopped, kinetic energy was low, and thermal energy was high.
4.) At all times, total energy = kinetic energy + thermal energy
hopefully my answered helped!
(If my answers helped you tell me, therefore I know.. that I did them correctly. Anyways, have a great day/night!)
