Answer the following statements true (T) or false (F)

1. What evolutionary advantage do flowers provide to angiosperms?
2. The common garden snail lacks a vertebrae and is a member of the mollusk phylum, therefore it is a deuterostome.
3. This statement is false. Nematodes have a complete digestive system, but tapeworms absorb nutrients from their host’s digestive system.
4. Hexapods have six legs, while the Chelicerates have eight.
5. The subclass Hirudinoidea, which includes leeches, have chaetae that allow them to attach to a host vertebrate for feeding.


1. True
This statement is true. Most animals reproduce sexually, although some species can also reproduce asexually, especially those without backbones.
2. False
This statement is false. The common garden snail lacks a vertebrae and is a member of the mollusk phylum, therefore it is a protostome.
3. False
This statement is false. Nematodes have a complete digestive system, but tapeworms absorb nutrients from their host’s digestive system.
4. False
This statement is false. Hexapods have six legs, while the Chelicerates vary in their number of legs (two per segment) with two special appendages for feeding.
5. False
This statement is false. The subclass Hirudinoidea, which includes leeches, have suckers that allow them to attach to a host vertebrate for feeding.

Rubisco is an important enzyme in the Calvin cycle because it acts as a carboxylase to catalyze addition of carbon dioxide and water to ribulose-1,5-bisphosphate, which then forms two molecules of 3-phosphoglycerate

Rubisco also acts as an oxygenase to catalyze addition of molecular oxygen rather than carbon dioxide to ribulose-1,5-bisphosphate. a) What is (are) the product(s) of the rubisco oxygenase reaction activity and why is this a problem for plants? b) Explain why rubisco's much lower affinity for oxygen than for carbon dioxide does not mitigate the rubisco oxygenase problem for plants. c) Identify the pathway plants use to metabolize the problematic product of rubisco oxygenase and the final fate of its carbons. d) Explain why the oxygenase activity of rubisco is particularly problematic for plants in arid environments. e) What strategies do plants in arid environments use to deal with this problem? What will be an ideal response?
