What is the difference between gene flow and genetic drift
I
Isaura F
InstructorGene flow is the transfer of genetic information from one population to another. Genetic drift is the variation of the relative frequency of a particular allele (version of a gene) within a population. Hope this helps!

whats a hydrogen bond?
E
Elizabeth P
InstructorHydrogen bonds involve a H atom that is covalently bonded to a highly electronegative atom (F, O, N) causing it to be partially stripped of its electrons by that atom.
This causes a transient attractive interaction to form between the partially positive H with another partially negative (electronegative) atom. Example: water (two Hs bound to one O) loves to interact with other water molecules in that way.
Hydrogen bonds are not covalent bonds, they are much weaker.

Are there any parts of the human body that get oxygen directly from the air and not from the blood?
I
Isaura F
InstructorSeems like the outer layers of skin and outer cornea (of your eyes) are able to get oxygen directly from air.

How does climate change affect wildlife in ontario?
I
Isaura F
Instructor"In Ontario, [one] can expect average temperatures to rise by as much as 3 to 8 degrees Celsius over the next century. Warmer temperatures will result in milder winters, longer growing seasons and a higher frequency of severe weather events such as record-breaking storms, floods, droughts and heat waves."
