Q: If your diet lacks iron (Fe), what might happen to you?
![Page 13: Dr. Stuart Reichler Bio 311D](https://reader031.vdocuments.us/reader031/viewer/2022032607/56649ec55503460f94bcf668/html5/thumbnails/13.jpg)
Q: If your diet lacks iron (Fe), what might happen to you?A: Iron is needed for hemoglobin to bind O2, without it O2 will not be distributed, and cellular respiration will stop.

Q: What does the inside of the small intestine look like, and how is the structure of the small intestine related to its function?
![Page 15: Dr. Stuart Reichler Bio 311D](https://reader031.vdocuments.us/reader031/viewer/2022032607/56649ec55503460f94bcf668/html5/thumbnails/15.jpg)
Q: What does the inside of the small intestine look like, and how is the structure of the small intestine related to its function?A: Any one of these descriptions is ok. It is undulated, it has villi, a large surface area. This large surface area is necessary for the efficient absorption of nutrients.

Q: Why are victims of severe burns also susceptible to infections?
![Page 17: Dr. Stuart Reichler Bio 311D](https://reader031.vdocuments.us/reader031/viewer/2022032607/56649ec55503460f94bcf668/html5/thumbnails/17.jpg)
Q: Why are victims of severe burns also susceptible to infections?A: The skin is an important barrier to pathogens. If it is damaged, pathogens can enter.

Q: During plant evolution, what plant cell type was necessary for the evolution of shoots? Explain.

Q: During plant evolution, what plant cell type was necessary for the evolution of shoots? Explain.A: Sclerenchyma, these thick-walled cells allow the needed support AND transport.

Studying Biology:
•Start with a question. –For example:
How? Why? When? Where? Etc?
•How do we get answers?–Strong Inference presents one method

Why are giraffes' necks so long?
![Page 22: Dr. Stuart Reichler Bio 311D](https://reader031.vdocuments.us/reader031/viewer/2022032607/56649ec55503460f94bcf668/html5/thumbnails/22.jpg)
Average feeding height

The primary function of the giraffes' long neck is not for feeding.
Most feeding occurs below neck height.

They do use their necks for fighting and defense.
