A compound is the chemical bonding of what
Answer:
A compound is a molecule made of atoms from different elements
Explanation:
All compounds are molecules, but not all molecules are compounds. Hydrogen gas (H2) is a molecule, but not a compound because it is made of only one element. Water (H2O) can be called a molecule or a compound because it is made of hydrogen (H) and oxygen (O) atoms.

What is the funtion of the lungs in the respiratory system? (Use complete sentences.)
Answer:
The lungs' main role is to bring in air from the atmosphere and pass oxygen into the bloodstream. From there, it circulates to the rest of the body. Help is required from structures outside of the lungs in order to breath
Explanation:
Explanation: The lungs are the most important part of the respiratory system. They give air to serve the whole entire body. Lungs are one of the most vital organs of the body, since they help us breathe, and if we did not breathe, we would die.

Cuticles allow them to grow bigger and taller.
Cuticles help them transport water.
Cuticles help prevent water loss.
Cuticles allow the performance of photosynthesis.
HELP PLS AND THX
Answer:prevention of water loss would be unnecessary
Explanation:
edge 2021
Cuticles are protective lining in the epidermal layer of plants. Cuticles helps to reduce water loss and protect the plants from environmental stresses.
What is cuticles?Cuticle is an organism's external layer or area that makes touch with the environment. The epidermis secretes the dead, noncellular cuticle in many invertebrate species. In humans, the cuticle is the epidermis, and this layer may include colours and chitin, similar to arthropods.
The cuticle is a protective coating that protects the epidermal cells of leaves and other organs while preventing water loss in some higher plants.
It is made up of cutin, a waxy, water-repellent compound related to suberin that is present in the corky tissue's cell walls. Hence, option c is correct.

To investigate how mechanical energy affects the number of times a ball will bounce back, Maria dropped a ball from three different heights. Which of the following would be a reasonable conclusion from this experiment?
The height from which a ball is dropped does not affect the number of times it bounces.
Increasing the height will give the ball more energy and will increase the number of times it bounces.
Increasing the height will give the ball less energy and will decrease the number of times it bounces.
Decreasing the height will give the ball more energy and will increase the number of times it bounces.
Answer:
Increasing the height will give the ball more energy and will increase the number of times it bounces.
An athlete runs at an average speed of 9.00 mph. If she wants to complete a distance of 42.19 km, she must jog for ____ x 10^2 min.
Fill in the blank.
The athlete must jog for approximately 1.7479 × 10² minutes to complete a distance of 42.19 km at an average speed of 9.00 mph.
To find the time the athlete must jog, we'll first convert the distance from kilometers to miles, then use the formula:
Time (in hours) = Distance ÷ Speed
1 kilometer is approximately 0.621371 miles.
So, the distance in miles is:
42.19 km × 0.621371 miles/km ≈ 26.21875 miles
Now, we can find the time in hours:
Time (in hours) = 26.21875 miles ÷ 9.00 mph ≈ 2.9131944 hours
To convert hours to minutes, multiply by 60:
Time (in minutes) ≈ 2.9131944 hours × 60 min/hour ≈ 174.79167 minutes
Now, let's round this to two decimal places and express the result in scientific notation:
Time (in minutes) ≈ 174.79 minutes
To write it in the requested form (using scientific notation), we move the decimal point two places to the right:
Time (in minutes) ≈ 1.7479 × 10 minutes
So, the athlete must jog for approximately 1.7479 × 10² minutes to complete a distance of 42.19 km at an average speed of 9.00 mph.

⚠️An irregular piece of iron has a mass of 78.7 grams. When placed in a graduated cylinder with 30 mL of water, the water rises to the 35 mL ⚠️
Answer:
The density of the iron is: 15.74g/cm3
Explanation:
-To determine the density of something, you have to divide the mass and the vol.
-mass/volume = density or, m/v = d
-The mass of the iron is: 78.7 grams
-The volume of the iron is 5mL
In order to find the density, you have to divide:
m/v = d
78.7g ÷ 5mL = 15.74

What does it mean for waves to be absorbed? Make sure to include energy in your explanation.
Answer:
The energy of a wave is transferred to the material it encounters. Ex.) When the ocean waves meet the shoreline, most of their energy is absorbed by the shore.
Explanation:
Ex.) When the ocean waves meet the shoreline, most of their energy is absorbed by the shore.
Wave absorption takes place when a wave transfers its energy to the atoms and molecules of the medium it comes in contact with.
What does it mean for a wave to be absorbed ?When a wave is absorbed, matter absorbs energy from the wave, lowering its amplitude. When a sound wave strikes foam padding, for example, the energy passes through the material and is sometimes converted into heat or other forms of energy.
The energy of a wave is transferred to the particles in the surface when it is absorbed by a surface. This usually causes the particles' internal energy to increase.
Some wavelengths or colors of light are absorbed when white light shines on an opaque object.
Thus, Wave absorption takes place when a wave transfers its energy to the atoms and molecules of the medium it comes in contact with.
