What different chemical reaction possible in test tube?
Typically, test tubes are composed of glass or plastic. They can be used to heat fluids, conduct chemical reactions, and even propagate living things.
An effective visual clue (a color change, precipitate, or gas production) as proof of a chemical reaction is often provided by a quick reaction carried out in a test tube.
One or more of the following events can indicate that a chemical reaction has occurred: The reaction flask's interior has undergone a color shift. Gas has developed. Typically, the presence of bubbles indicates that a gas has formed.
Therefore, A new substance was forming

A city is located in an area that has experienced 7.5-magnitude earthquakes in the past. The city is considering building a new skyscraper.
Use the earthquake magnitude scale to predict the amount and type of damage residents should expect from future earthquakes of similar magnitude. Then suggest a way to minimize the effects of future earthquakes on the skyscraper.
Answer:
The residents should expect collapsing parts of the building, or even the building itself would collapse if the building cannot hold/not sturdy enough for earthquakes ranging around 7.0m to 7.9m. If the building is built by hills or rocky land, expect landslides to be happening. A way effects of future earthquakes can be minimized is that the building should be constructed with sturdy material (such as steel) so that it can withstand most of the force of a 7.0-7.9m earthquake.

What is the purpose of protein synthesis?
Answer:
Protein synthesis is the process all cells use to make proteins, which are responsible for all cell structure and function. There are two main steps to protein synthesis. In transcription, DNA is copied to mRNA, which is used as a template for the instructions to make protein.
Explanation:
Proteins are one of the most important biomolecules essential for the survival of organisms owing to the myriad of functions that they play in the physiological system.
Proteins that are ingested are easily degraded to amino acids or peptides by the action of HCl in stomach and the digestive enzymes present in the gastrointestinal tract. Thus, proteins have to be synthesized in the body to meet the body's needs for various functions.
Some of the functions of proteins include:
1. Enzymes are majorly proteinaceous in nature and are required for crucial functions, including cell division and DNA synthesis.
2. Motor proteins help in movement and also provide cytoskeletal structure to the body.
3. They are required for the functioning of the immune system.
4. Proteins are required for cell signaling pathways.

Your friend Olivia has a blemish on her shoulder that she can't easily see herself, so she asks you to check it out for her to help her decide if she should see her doctor. What are at least three things you would look for to help you advise her? (Remember: ABCDE!)
Answer:
Explanation:
There are a couple of things you can look for when analyzing your friend's blemish to determine whether she should see a doctor or not. Three of these signs are
Discoloration or texture on the blemish.The blemish is itchy or irritated.The blemish is bleeding
All three of these are signs that Olivia should see a doctor/dermatologist as soon as she can. This is because all of these point to skin cancer. A regular blemish is a single color and is imbedded within the skin. It does not appear textured or out of the skin, or even two or three different colors. Blemishes also are not itchy or bleed. Therefore, any of these signs would be a cause for concern.
