The Answer of gonorrhea and whooping cough and cholera and is...

Question 2

The ____ spend most of their lives as individual haploid organisms.
A) cellular slime molds
B) plasmodial slime molds
C) amoebas
D) multicelled protists
E) single-celled protists

Accepted Answer

Cellular slime molds spend most of their lives as individual haploid cells. They only come together to form a multicellular structure during certain stages of their life cycle, such as when food is scarce.

Question 3

The close relationship between ____ and animals can be seen in the similarity of these protists and sponges, simple animals.
A) cellular slime molds
B) choanoflagellates
C) diatoms
D) brown and red algae
E) flagellates protozoans

Accepted Answer

Choanoflagellates have a similar structure to the collar cells found in sponges, which are among the simplest animals. This close relationship suggests that choanoflagellates played a crucial role in the evolution of animals.

Question 7

Agar is produced by ____.
A) brown algae
B) red algae
C) phycobilins
D) brown and red algae
E) red algae and phycobilins

Accepted Answer

Agar, a gelatinous substance, is produced by red algae. It is commonly used in microbiological culture media and as a thickener in foods.

Question 8

Red algae ____.
A) are primarily marine organisms
B) are thought to have developed from green algae
C) contain xanthophylls as their main accessory pigments
D) are actually brown
E) are primarily freshwater organisms

Accepted Answer

Red algae are primarily marine organisms, thriving in both deep and shallow saltwater environments. They are known for their distinctive red coloration, which comes from the presence of phycoerythrin, a pigment that allows them to photosynthesize in deep waters where light is limited.

Question 9

Diatoms are characterized by ____ and are the source of economically useful_____.
A) calcium carbonate shells; ozone
B) calcium carbonate sheaths; petroleum
C) silica shells; diatomaceous Earth
D) silica sheaths; limestone
E) silica carbonate shells; diatomaceous Earth

Accepted Answer

Diatoms are characterized by silica shells and are the source of economically useful diatomaceous Earth, which is used for filtration, pest control, and as a polishing agent.

Question 10

____ is the best studied species of bacteria.
A) Rhizobium sp.
B) Prevotella copri
C) E. coli
D) G. lamblia
E) Agrobacterium sp.

Accepted Answer

E. coli is one of the best studied species of bacteria due to its importance in molecular biology and biotechnology.

Question 11

Algins, thickening compounds used in the food industry, are obtained from ____.
A) foraminiferans
B) brown algae
C) dinoflagellates
D) red algae
E) green algae

Accepted Answer

Algins or alginates are primarily obtained from brown algae. They are used as thickening, stabilizing, emulsifying, and gelling agents in various food products.

Question 12

The ____ protists may cause dysentery after drinking contaminated water. amoeba
A) dinoflagellate
B) apicomplexan
C) amoeba
D) ciliate
E) water mold

Accepted Answer

Only amoebas are known to cause dysentery after drinking contaminated water. Dinoflagellates cause red tides, apicomplexans cause diseases such as malaria, ciliates are important in aquatic ecosystems but do not typically cause disease, and water molds can cause plant diseases but not dysentery in humans.
