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.

Why does Mercury have almost no atmosphere?
Mercury spins on its axis too fast to have an atmosphere.
Radiation from the Sun blows the atmospheric particles off into space.
Mercury's gravity is too weak to hold an atmosphere.
Mercury orbits the Sun at such high speed that the atmosphere is blown away.
Answer:
There are two main reasons. First, Mercury is small and doesn't have much gravity so it's hard to hold onto an atmosphere. Second, Mercury is close to the Sun so any atmosphere gets blasted away by stuff being blown off the Sun.
Explanation:
Because Mercury has no atmosphere, it can't hold onto its heat very well. The night side of Mercury gets very cold, which brings down the average temperature of the planet and makes it only the second hottest planet in the Solar System after Venus.

Explanation:
Is a change in matter that produces one or more substances
Chemical change
Physical change
Chemical reaction
Answer:
Chemical change
Explanation:
A chemical change happens when one chemical substance is transformed into one or more different substances, such as when iron becomes rust. Chemical changes occur through the process of chemical reactions, and the resulting substances have different properties because their atoms and molecules are arranged differently.
its not physical change: What is a physical change? A physical change is a change to the physical—as opposed to chemical—properties of a substance. They are usually reversible. The physical properties of a substance include such characteristics as shape (volume and size), color, texture, flexibility, density, and mass.
its not chemical reaction: A chemical reaction is a process in which one or more substances, also called reactants, are converted to one or more different substances, known as products. A chemical reaction rearranges the constituent atoms of the reactants to create different substances as products

Answer:
The amount of water vapor in a given volume of air is humidity.The amount of water vapor in the air at any one time depends on temperature . Warmer air holds more water than cooler air. Clouds form when humidity is low and thetemperature is high . Relative humidity is defined as the amount of water vapor in the air divided by the amount that would have to be present in the same air to form a cloud or condense on a surface. Dew is related to the humidity of the previous day. The air temperature at which water vapor in the air condenses onto cool surfaces is the dew point.

If two oceanic plates move towards each other at a convergent boundary, then_____ may occur.
earthquakes
faults
ocean formation
mountains
volcanoes
island chains
seafloor spreading
pick two events
Answer:
I think the answer is Volcanoes.
Explanation:
If the two plates that meet at a convergent plate boundary both are of oceanic crust, the older, denser plate will subduct beneath the less dense plate. The older plate subducts into a trench, resulting in earthquakes. Melting of mantle material creates volcanoes at the subduction zone.
When two oceanic plates converge, the denser plate will end up sinking below the less dense plate, leading to the formation of an oceanic subduction zone. Old, dense crust tends to be subducted back into the earth. An example of a subduction zone formed from a convergent boundary is the Chile-Peru trench.

Explanation:
Sixth-grade students conduct a laboratory experiment investigating the flow of thermal energy. They place a sealed plastic bag filled with water at 60°C into a beaker filled with an equal amount of water at 80°C. They then put the beaker with the plastic bag in an insulated container.
Based on the flow pattern of thermal energy, what can students predict will most likely happen in about an hour?
A. Thermal energy will flow from the cooler water in the plastic bag to the warmer water in the beaker so that the temperature of the water in the beaker will be 60°C and the temperature of the water in the plastic bag will be 80°C.
B. Thermal energy will flow from the warmer water in the beaker to the cooler water in the plastic bag so that the temperature of the water in the plastic bag will be 80°C and temperature of the water in the beaker will be 60°C.
C. Thermal energy will flow from the warmer water in the beaker to the cooler water in the plastic bag so that the temperature of the water in both the plastic bag and the beaker will be 70°C.
D. Thermal energy will flow from the cooler water in the plastic bag to the warmer water in the beaker so that the temperature of the water in both the beaker and the plastic bag will be 70°C.
