Solution
Answer:
42). D). 2 and 4
Chemotrophs are organisms that obtain energy by the oxidation of electron donors in their
environments. These molecules can be organic (chemoorganotrophs) or inorganic
(chemolithotrophs). The chemotroph designation is in contrast to phototrophs, which utilize solar
energy.
43). D). 2 and 3
Archaea and bacteria are both prokaryotes, meaning they do not have a nucleus and lack
membrane-bound organelles. They are tiny, single-cell organisms called microbes, which cannot
be seen by the naked human eye.
44). A) extreme halophiles
45). B). Flagella and a lack of mithochondria. Giardia is an example
The diplomonads are a group of flagellates, most of which are parasitic. They include Giardia
lamblia, which causes giardiasis in humans. They are placed among the metamonads, and appear
to be particularly close relatives of the retortamonads.
46). A). Apicomplexa
The Apicomplexa are a diverse group that includes organisms such as the coccidia, gregarines,

2. piroplasms, haemogregarines, and plasmodia. Diseases caused by Apicomplexa include:
Babesiosis (Babesia) Malaria (Plasmodium) Cryptosporidiosis (Cryptosporidium parvum)
