Collecting data is part of a. coming to a conclusion. b. doing the experiment. c. gathering material. d. stating the problem.
b. doing the experiment.

What is the soil food web?
The soil food web refers to the RELATIONSHIPS among the wide range of living ORGANISMS found in the SOIL, and those relationships work on the premise that everything that can eat or be eaten is involved in a CYCLICAL relationship.

What are the by products that are produced by Fermentation?
Lactate or Ethanol (alcohol) and Carbon Dioxide (CO2)

What are the 5 shapes that bacteria can by classified into?
The five shapes that bacteria can be classified into are: Cocci (round), Spirilla (Spiral), Bacilli (Rod), Vibrio (Comma shaped), and Filamento.

What makes bread rise?
Carbon dioxide bubbles produced by the yeast consuming the glucose in the flour as it goes through alcoholic fermentation.

During the experimental stage of the scientific method. a. a hypothesis is formed. b. measurements are often made. c. most scientists draw their conclusion. d. a scientific law is written up.
b. measurements are often made.

Name three positive effects of having bacteria in our soil.
Nitrogen Fixing (converts nitrogen in the air to a form usable by plants) Recycle organic material, Feed other organisms, Ward off diseases, Help water move through the soil more easily.
300
What do the words Anaerobic and Aerobic mean?
Anaerobic means without oxygen, and aerobic means with oxygen.
300
What are three bacterial arrangements that we studied?
1. Diplo when bacteria are grouped in pairs. 2. Strepto when they are arranged in chains. 3. Staphylo when they are bunched together.

What makes yogurt thicker than milk?
Lactic acid is produced by the bacteria as a waste product as it consumes the lactose in milk and lowers the pH and curdles the milk making it thicker.
400
Before the hypothesis can be stated a a. theory is proposed. b. galactic law is constructed by a group of professors. c. conclusion is agreed upon. d. problem needs to be stated in the form of a question.
d. problem needs to be stated in the form of a question.

Why do we need decomposers?
We need decomposers because they break down organic material,(that is everything this is or once was living), and replenish the nutrients of the soil. If we did not have decomposers our world would be covered with monster piles of dead stuff, and the soil would no longer be able to grow any plants
400
How many molecules of ATP are formed through Anaerobic Cellular Respiration, and how many molecules of ATP are formed through Aerobic Cellular Respiration?
2 molecules of ATP are formed through Anaerobic Cellular Respiration, and Aerobic Cellular Respiration can form up to 29 molecules of ATP.
400
What are the two words used to describe how bacteria reproduce?
Binary fission and asexual reproduction.

What happens while Cheddar Cheese is aging?
The bacteria is producing lactic acid and the taste is becoming sharper.

What are the 5 steps of the scientific method?
1. Make an observation 2. Ask a question 3. Form a hypothesis 4. Conduct an experiment 4. Accept or Reject your hypothesis
500
Of these three options which one probably contains the most bacteria? 1.Toilet seat 2.Garden soil 3.Computer keyboard
Garden Soil

What is happening during Alcoholic Anaerobic Fermentation?
Sugars such as glucose are being broken down into Ethanol and CO2 in an environment without Oxygen producing 2 molecules of ATP. Bonus Points! This happens through Glyclolysis and Fermentation.
500
What can some bacteria excrete to digest food outside of its cell?
Bacteria can excrete enzymes to break down food on the outside into nutrients that the bacteria can use.
500
Why did humans start making foods through fermentation like cheese and sauerkraut?
As a preservation method, so that the food would last longer.
