Are bacteria eukaryotic or prokaryotic?
- A.
  
  Eukaryotic
- B.
  
  Prokaryotic
- C.
  
  I'm not sure
Correct Answer
B. Prokaryotic

Explanation
Bacteria are prokaryotic organisms. Prokaryotes are single-celled organisms that lack a nucleus and membrane-bound organelles. Bacteria have a simple cellular structure without a nucleus, and their genetic material is located in the cytoplasm. This distinguishes them from eukaryotes, which have a true nucleus and other membrane-bound organelles. Bacteria are known for their ability to adapt and survive in various environments, and they play important roles in processes such as decomposition and nutrient cycling.

What are three benefits of microbes?
- A.
  
  They cause no diseases, they purify water, and they kill pests.
- B.
  
  They help with making cotton, fertilizes the ground, and produce food.
- C.
  
  They kill pests, they are in the production of foods, and help with wastewater clean-up.
Correct Answer
C. They kill pests, they are in the production of foods, and help with wastewater clean-up.

Explanation
Microbes provide several benefits including pest control, food production, and wastewater clean-up. They help in killing pests, which can be beneficial for agriculture and human health. They also play a crucial role in the production of various foods such as cheese, yogurt, and bread. Additionally, microbes are involved in wastewater treatment processes, where they help break down organic matter and remove pollutants, contributing to water purification.

What are three ways that microbes help in food production and industrial uses?
- A.
  
  Bacteria help in dairy production, Algae helps with petroleum production, and Yeast is in the production of bread.
- B.
  
  They all help in the production of honey, Yeast is in bread production, and Fungi and bacteria help with the production of antibiotics.
- C.
  
  Yeast and bacteria are in the production of medicines, yeast is in bread production, and they are all in the production of cough syrup.
Correct Answer
A. Bacteria help in dairy production, Algae helps with petroleum production, and Yeast is in the production of bread.

Explanation
The correct answer states that bacteria help in dairy production, algae helps with petroleum production, and yeast is used in the production of bread. These are all examples of how microbes are utilized in food production and industrial processes. Bacteria play a crucial role in fermenting milk to produce dairy products such as cheese and yogurt. Algae can be used to produce biofuels and other petroleum-based products. Yeast is commonly used in baking to ferment the dough and produce bread. Overall, these examples highlight the diverse ways in which microbes contribute to various industries.

6.

All of the microbes may contaminate water.
- A.
  
  True
- B.
  
  False
Correct Answer
B. False

Explanation
Not all microbes contaminate water. While some microorganisms, such as bacteria, viruses, and parasites (e.g., E. coli, Giardia, and Cryptosporidium), can contaminate water and pose health risks, many microbes are harmless or even beneficial. Some bacteria play essential roles in breaking down organic matter or maintaining ecological balance in water systems. Therefore, it's inaccurate to say that all microbes contaminate water.
