How to grow bacteria?

Answers

Answer 1

Answer: Hey there! Now that I know its for your science project , Id be more than happy to help ( if this was from your text book, It might have not been right since some text books might not mention the method I would have given you)

Sooo.. Here we go.. For my science project This is the method I used...

step 1 ) Go to your fridge
step 2) Go grab a piece or two of white or wheat toast. Its preferable to use both so you can see and compare the difference.
step 3) (before you do anything else, since it is a science project, your teacher might want a hypothesis, with observations and data, and a conclusion to your experiment, so just make sure you have those done if you have to.)
Step 4) go get 2 Ziplock bags, preferably the one that you zip and seal..
Step 5) Place the wheat toast in one bag, and place the other toast in the other bag...
Step 6) Make sure that when you put the toast in the bags , you take all the air out of the bag, make sure there is no air at all!
Step 7) put the toasts in a dark place with no light and very little air. The place I put them was the closet that I never opened.
Step 8) Leave them there for about 7-9 days
Step 9) Take it out...
The results are going to be gross... you should see weird fuzzy things (mold,fungus, bacteria, etc.)
Thats when your project is complete..

PLEASE DO NOT TOUCH OR EAT THE TOAST.. WHERE PLASTIC GLOVES WHILE HANDLING THE TOAST, BECAUSE IT CAN GET YOU SERIOUSLY SICK!!!! DISPOSE OF IT AFTER YOU ARE DONE! THANK YOU!

How is a runner's speed affected by wind?

Answers

A tailwind will boost up the speed of the runner while a headwind will slow the runner down.

Explanation:

A tailwind is a wind that is blowing along the direction of the runner approaching. Whereas a headwind is the wind that blows opposite to the runners approach.

This happens because the body is actually running flat to the wind which gives a resistance to the wind flow. So the wind actually pushes the body forward or backward. If the wind is coming from back, the wind pushes the athlete towards front, increasing his speed by a few miles per hour. When the wind is coming from front, the wind is actually pushing the athlete backwards, which decreases the speed.

The wind also makes it difficult for the athlete to breathe, thereby decreasing the speed to a certain extent in general.

Answer:

I would set up the wind machine so it was blowing against people running. I would have it blow at different speeds in different trials. I would use a stopwatch to record the time of each trial for the runners. I would use the computer to help analyze the data from the trials.

How does the grand canal promote transport of goods in China

Answers

The Grand Canal is the longest canal in the world. It is also a famous tourist destination. The canal was first constructed during the Sui dynasty. The King Fu Chai of Wu ordered the digging of the canal between the Yangtze and the Huaihe River for the purpose of transporting troops to launch an attack on to the state of Qi. In 605 A.D., emperor Yang Di established the Eastern Capital in Luoyang and this is how the trasport of goods was promoted in the Grand Canal.

If a scientist creates a new rock-like substance in a laboratory, why wouldn't this type of material be classified as a true mineral?Question 5 options:

A There are no planes of weakness in its lattice structure

B It's not a naturally occurring substance

C It's too new to be a mineral

D It would not be hard enough

Answers

B It's not a naturally occurring substance

Minerals are naturally occurring substances that form in geological processes. Since the scientist created this rock-like substance in a laboratory, it wouldn't be classified as a true mineral because it didn't occur naturally in the Earth's geological processes.

The reason why a new rock-like substance created in a laboratory would not be classified as a true mineral is because it does not meet one of the essential criteria for being considered a mineral: being a naturally occurring substance.

Minerals are formed naturally through geological processes over long periods of time. They are typically found in the Earth's crust or other natural environments. However, the substance created in a laboratory is artificially synthesized, meaning it is made by humans in a controlled setting rather than being formed naturally.

For example, if a scientist combines different chemical compounds in a lab and creates a rock-like substance, it may have similar physical properties to a mineral, such as hardness or color. However, since it was intentionally made by humans, it does not qualify as a true mineral.

Therefore, the correct answer is B: It's not a naturally occurring substance
