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!

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."
