Use complete sentences to explain how the mass of hydrogen is conserved during cellular respiration.

pls make it simple and not write a whole paragraph

Answers

Answer:

Explanation:

The mass of hydrogen is conserved during cellular respiration as it follows the Law of Conservation of Matter.

Answer:

the law of conservation of matter

Explanation:

The mass of hydrogen is conserved during cellular respiration as it follows the Law of Conservation of Matter.

The Law of Conservation of Matter states that the reactants must equal the products, which is demonstrated through the equation that demonstrates cellular respiration.

C6H12O6 + 6O2 -> 6CO2 + 6H20

This shows that hydrogen has been conserved throughout the entire process (H representing Hydrogen) as the product has the same amount of hydrogen as the reactants.

How is radiant energy from the microwave transformed into heat energy?

Answers

The waves emitted from the microwave sends the molecules within the object into a faster motion. The heat is generated from the faster movement of the molecules in the object. ... It is only transformed into new substances or energies.

Radiant energy comes from gravitational and electromagnetic radiations. This energy from the microwave is transformed into heat energy by the faster-moving molecules.

What is energy conversion?

Energy conversion is the process of transformation of the energy from one form to another that also follows the law of conservation of mass or matter. Radiant energy is the heat or energy that is given out by electromagnetic waves in the form of various waves.

This radiant energy has its own characteristics that differentiate it from other waves. The waves from radiant energy have a molecular speed that gets increased by the temperature and this increases collision and kinetic energy producing new substances and generating heat.

Therefore, the movement of particles in microwave transforms the radiant energy into heat energy.

Why do scientists use models, and why do all models have limitations???
Plsss help! :) I will give brainliest!! :)

Answers

Answer:

Scientists use  models to represent data/evidence. However, all models have limitations. However, models are simplified versions of reality, and can't be totally accurate in representation.

Hope this helps :)

Answer:

Since models are simpler than real objects or systems, they have limitations. ... It may not predict the behavior of the real system very accurately. But the more computing power that goes into the model and the care with which the scientists construct the model can increase the chances that a model will be accurate.

Organisms can either be made of one cell or made of more than one cell

Answer:

The statement is true.

Explanation:

Organisms can be unicellular (made up of one cell) or multicellular (consisting of more than one cell).

I hope this helps in any way :)

Unicellular organisms are made up of only one cell that carries out all of the functions needed by the organism, while multicellular organisms use many different cells to function. Unicellular organisms include bacteria, protists, and yeast.

Many different kinds of molecules tha combine to form an extended structure.

Many different kinds of atoms that can move freely past each other.

Answers

Based on the atomic arrangement of quartz, it is can be concluded that quartz is an extended structure that is made of repeating patterns of atoms.

What is quartz?

Quartz is a hard crystalline mineral found within the Earth's crust and which is composed mainly of the mineral silica. Silica is mostly silicon(iv) oxide.

Quartz is colourless and its crystalline structure is of a hexagonal prism. The atoms are arranged in a regular repeating grid to form the hexagonal crystal.

Therefore, it is can be concluded that quartz is an extended structure that is made of repeating patterns of atoms.
