What is the difference between gene flow and genetic drift 

Isaura F

Instructor

Gene 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?

Isaura F

Instructor

Seems 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? 

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."
