Answer:
convection current waves
Explanation:
The study of chemicals is called chemistry.
The correct answer is D.
The heat convention is stated as the transfer of heat from one place to another due to the movement of fluid. Although often discussed as a distinct method of heat transfer, convective heat transfer involves the combined processes of conduction and advection.
According to the question, the warm air rises up and travels along with the air.
The hot air also has a high temperature due to which the radiation of the heat transfer from one place to another.
Hence, the correct answer is D that is Warm air rises and takes heat with it; eventually, it cools and sinks.

How is energy involved in physical change?
During phase changes, energy changes are usually involved. For example, when solid dry ice vaporizes (physical change), carbon dioxide molecules absorb energy. When liquid water becomes ice, energy is released. Remember that all chemical reactions involve a change in the bonds of the reactants.

Answer:
75% straight
50% bent
Explanation:
because the Punnett Squares work that way
think of it as a multiplication table...when 2 numbers come to the middle, they give you the answer just like these squares (they're just smaller)
R + R = RR
R + r = Rr
R + r = Rr
r + r = rr
RR is 25%
Rr is 50% because there are 4 boxes and 2 of them is Rr
rr is 25%
Simpler answer:
I know because 25% + 50% = 75% for the straight root. 25% + 25% = 50% for the bent toot.

Rosa eats a peanut butter sandwich for lunch. Peanut butter contains a lot of protein, and bread is mostly starch. Rosa plans to go for a run later this afternoon. Rosa is breathing normally.What does she need from the food she ate and the air she breathes so that she can go on her run? (Sentence starter: The molecules Rosa needs from the food she eats and air she breathes are...
Answer: What does she need from the food she ate and the air she breathes so that she can go on her run?
A. Rosa needs carbohydrates rich food (bread) to carry out her jogging activity. Protein-rich food before exercise is not recommended unless she is on a weight loss program (diet plan).
B. Rosa needs oxygen to perform aerobic respiration, which is required for maximum release of energy (36 molecules per reaction run). Anaerobic reactions yield less energy (2 molecules of ATP per reaction run) and are not recommended.
How do Rosa's body systems work together to get the molecules she needs into her cells?
Rosa's body cells need carbohydrates (glucose) and oxygen to perform aerobic respiration for the release of maximum energy. The glucose and oxygen molecules are provided to the cells via diffusion into the bloodstream. During exercise/jogging, complex molecules of carbohydrates such as starch (present in bread) are broken down into simple molecules (glucose) which are diffused into the blood. Likewise, a high amount of oxygen is provided to the body's cells via diffusion in blood, which is carried out by the faster movement of lungs and heart. The combined action results in the supply of both types of molecules to enter the cell where mitochondria use these substrates to produce energy molecules (ATPs).
How do hair cells use these molecules to release energy for her body to run?
The substrates (glucose and oxygen) enters the bloodstream and then taken up to the cell. Then they are provided to the mitochondria for the release of energy in the form of ATP. This is why mitochondria are known as the powerhouse of the cells. Within the cell, energy is released in a three-step process, i.e. glycolysis, the Krebs cycle, and oxidative phosphorylation. Here glucose reacts with oxygen. In the end, aerobic respiration per reaction run produces 36 molecules of ATP which are sufficient to meet intensive energy needs. During excrcise, the supply of oxygen and glucose is also faster due to faster lungs and heart actions.
PS: Anaerobic respiration cannot meet energy demands faster because the reaction produces only 2 ATP molecules per reaction run.
Explanation:
The molecules Rosa needs from the food she eats and air she breathes are
Food which are rich in carbohydrate to help her jog. This is because she is on a weight loss program which needs her to avoid proteinFurthermore, she would need oxygen so that she can successfully have aerobic respiration where there would be maximum release of energy to enable her complete her run better
According to the given question, we can see that Rosa wants to lose weight and she takes peanut butter which she takes and she is breathing normally which helps her perform aerobic respiration.
As a result of this, we can see that there is a need for Rosa to have the right diet which would help her with her jogging and weight loss program.
This would need foods that are rich in carbohydrate which would enable her to lose weight better and oxygen so that she could be efficient with her jogging and burn fat.

2. 1. Your best friend has missed a lot of school recently. Your teacher has allowed you to create a study guide and will let your friend use it on the test.
The guide should include:
• descriptions of amplitude, wavelength, frequency, and wave speed.
• Give examples of the wave relationship between amplitude and wavelength (if there is no relationship, explain how you know)
• Give examples of the wave relationship between wavelength and frequency (if there is no relationship, explain how you know)Text to speech
Answer:
Hi (best friend)! Here is what you missed!
Five wave parameters are defined and measured: the time, the frequency, the amplitude, the wavelength, and the speed. The wave length is the time it takes to pass a full phase. The frequency is just the opposite; it's the number of wave cycles that have been completed in a second.
Lets give a wave of water as an example. Its wavelength is the distance from crest to crest or from trough to trough. The wavelength can also be thought of as the distance a wave has traveled after one complete cycle—or one period. The time for one complete up-and-down motion is the simple water wave’s period T. In the figure, the wave itself moves to the right with a wave velocity vw. Its amplitude X is the distance between the resting position and the maximum displacement—either the crest or the trough—of the wave.
