Answer the following statements true (T) or false (F)
1. Protists can be autotrophs.
2.Slime molds may exist as either single amoeboid cells or large masses of cells that behave as one multicellular organism.
3.Water molds are unlike fungi in that water molds have diploid filaments and cell walls containing cellulose, whereas fungi have haploid filaments and cell walls containing chitin.
4.Molecular evidence suggests that plants and green algae did not descend from a common ancestor.
5.Stomata allow plants to exchange carbon dioxide and oxygen with the atmosphere.
1.TRUE
2.TRUE
This growth form of the slime molds allows exploitation of varied resources and opportunity for distribution.
3.TRUE
Classification of the water molds within the Protista kingdom, separate from the Fungi kingdom, is partially supported by their genome, and partly due to the different cell and genetic structures of their filaments.
4.FALSE
5.TRUE

The correct functions of your lungs contribute to the normal pH level of between 7.35 and 7.45. If your lungs do not exchange and remove carbon dioxide from your blood, the blood pH will change. A pH 6.4 reading of your blood indicates
A. a health problem due to the pH value being 10X higher OH- concentrations than normal in your body.
B. a health problem due to the pH value being 2X higher OH- concentrations than normal in your body.
C. a health problem due to the pH value being 2X higher H+ concentrations than normal in your body.
D. no health risk, as part of normal pH changes in your body that in this case bring it closer to neutral pH.
E. a health problem due to the pH value being 10X higher H+ concentrations than normal in your body.
