What chemicals can help an enzyme build up or break down substrates into
products?
Proteins can help enzyme to build up or break down substrates into products.
What do you mean by enzymes?Enzymes are proteins that act as biological catalysts by accelerating chemical reactions. The molecules upon which enzymes may act are called substrates, and the enzyme converts the substrates into different molecules known as products.
Enzymes are proteins that help speed up metabolism, or the chemical reactions in our bodies. They build some substances and break others down. All living things have enzymes.
An enzyme is a biological catalyst and is almost always a protein. It speeds up the rate of a specific chemical reaction in the cell. The enzyme is not destroyed during the reaction and is used over and over.

In class, students performed an experiment in which they used an egg as a representative cell. After removing the outer
shell, students placed the egg with its intact cell membrane into sugar solution that contains 80% sugar and 20% water.
That sugar solution would be blank to the egg and water would move blank the egg.
A. Hypertonic; out of
B. Hypotonic; out of
C. Isotonic; into
D. Hypertonic; into
Answer:
it would be A. Hypertonic; out of
The net migration of water in a hypertonic solution will be from the body into the solution. Plasmolysis, a process that causes cells to shrink and die when they are immersed in a hypertonic solution.Thus, option A is correct.
What Hypertonic movement removing the shell of egg?By means of osmosis, water enters and exits cells. When a cell is in a hypertonic solution, water leaves the cell when the solution becomes isotonic and the solution has a lower water concentration than the cytosol of the cell.
When someone excretes too much water without also excreting electrolytes, they experience hypertonic dehydration, which results in a high sodium content in the fluid surrounding their cells (also known as extracellular fluid).
Therefore, In contrast to the solution inside the egg, a concentrated sugar solution is hypertonic. As a result, water leaks out of the egg when it is submerged in the concentrated sugar solution, making the egg shrivel.

The process of photosynthesis takes place in the green plants only due to the presence of the chlorophyll and materials such as sunlight, water, carbon dioxide is required for the process of photosynthesis. Photosynthesis has the process in which green plants prepare their own food
The main effect of the ultraviolet light on plant growth has during the process of photosynthetic active radiation under the high level, UV -B light increases the net plant photosynthesis in several plant species.

Answer:
We should not allow mosquitoes to breed in our surroundings because Mosquitos act as a vector for bacteria and viruses, responsible for diseases such as malaria, dengue, encephalitis, and yellow fever.

Explanation:
In the light, plant leaves undergo photosynthesis, using CO2, water, and light energy to produce food. In the dark, plants cannot perform photosynthesis. Click Reset (), then click on the light switch to turn off the lights. Click Play to run the experiment in the dark. What happens?
Answer:
The plants leaves do not produce ATP
Explanation:
ATP molecules are only produced during the light phase of photosynthesis. They are not produced during the dark phase.
Hence, when the light is switched off, ATP molecule is no longer produced showing that photosynthesis is no longer going on.
Wayne thinks that DNA is only present in cells that need the information to make proteins. Sandy disagrees, and thinks that all cells have the same DNA, and they only make proteins from the genes that they need. Who is correct? Give specific evidence.
Answer:
The correct answer is: Sandy is correct, all cells contain all the DNA.
Explanation:
Sandy is the one who is making the correct statement here because all cells (minus some exceptions) contain ALL the DNA. Different cells have different requirements so each cell will translate into proteins the part of the DNA that has the specific gene for the protein the cell needs to synthesize.
For example, excitatory cells like neurons or cardiac cells need gated ion channels that are made of specific proteins to allow the passing of molecules like sodium and potassium. For this reason, these cells will use a particular gene in the DNA, adapt it into an mRNA strand through a process called Transcription, and then use different structures such as ribosomes and tRNA to help synthesize the protein needed from that mRNA strand (this process is called Translation).
All of the parts of the DNA that are not used by a cell will remain silent, while the genes that are used are expressed in the cell. This disparity between different parts of the DNA is thanks to the process of gene regulation, which "turns genes on and off".

Use the model below to explain how the sound from the ambulance’s siren appears to change as it drives past the girl. Why does the girl hear the sound differently as the ambulance travels past her?
Develop your claim of why the girl hears the sound differently as the ambulance travels past her. *
Answer:
The girl hears the ambulance sound different. The first part of the picture shows the girl and the sound waves, and they are right in front of her, so she cannot hear them as well. But the second image shows the girl in the middle of the sound waves. This is the strongest and loudest part of the sound waves, so it sounds different to the girl in the image.
Also, in the first image, the sound waves would most likely sound higher than in the second image. The sound would continue to get lower in frequency the father it drove away. This is because of the Doppler Effect. The Doppler Effect refers to the change in wave frequency during the relative motion between a wave source and its observer.

Which best describes the distribution of communities on a tall mountain?
A short story of about how the carbon cycle work
NAME _______________________
Instructions: Read each problem carefully and solve. Use the space below each problem to show your work and explain your thinking.
1. James decided to make his mother a cake for Mother’s Day. As he checked the recipe to make sure he had all the items he needed, he noticed that it required 30 deciliters of milk. He already has 1 liter of milk in the refrigerator. How many liters of milk will he need to buy for the cake recipe?
2. Eric and Paul both made airplanes in afterschool. They decided to have a contest to see which plane could fly the longest distance. Eric’s plane flew 6 meters. Paul’s plane flew 68 centimeters. Which plane flew the longest distance and how much father did it fly?
3. Ansley and her family decided to go to the beach for summer vacation. As they prepared to leave for their trip, her father programmed their GPS with the address of their beach house in D
Answer:
Part "3" of this question is incomplete
Explanation:
1) It should be noted that 10 deciliter equals 1 liter, thus if James has 30 deciliters, he will require ? liters of milk in total
10 ⇒ 1
30 ⇒ ?
? = 30/10
? = 3 liters
James will require 3 liters of milk in total. So, since he has 1 liter at home, he will need to buy 2 liters (2 +1 = 3) more
2) Eric's plane flew 6 meters ⇔ 600 centimeters (since 1 meter equals 100 centimeters)
Paul's plane flew for 68 centimeters
From the above, it can be deduced that Eric's plane flew the longest distance and also flew farther by 532 centimeters (600 - 68 = 532)
3) This question is incomplete
