Draw an energy flow diagram showing the energy transformation from one form to another.
ANSWER FAST PLEASEEE
Energy transformations convert one form of energy into another form of energy such as in batteries where chemical energy is converted to electrical, light and heat energy.
What is energy transformation?Energy transformations are changes which occur between different energy forms such that one energy form is converted to another form of energy.
Some examples of energy transformation are as follows:
electric fan converts electrical energy to mechanical energy generators convert mechanical energy to electrical energy electric cookers convert electrical energy to heat energy. chemical energy in batteries converted to electrical, light and heat energyTherefore, energy transformation convert one form of energy into another form of energy.

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
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.
Hydrogen peroxide is commonly used to clean cuts and wounds. Its chemical formula is
H2O2. This compound has _____.
two atoms of hydrogen
three atoms of oxygen
three atoms of hydrogen
one atom of oxygen

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

Quartz, or silicon dioxide (SiO2), is one of the most abundant minerals on Earth. The diagram shows the atomic arrangement of quartz.
Based on the diagram, which statement best describes the atomic arrangement of quartz?
Group of answer choices
An extended structure that is made of repeating patterns of atoms.
A repeating pattern of small molecules that can move freely past each other
Many different kinds of molecules tha combine to form an extended structure.
Many different kinds of atoms that can move freely past each other.
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.

What is energy? (science question , i'm on flvs so if you are too and in grade 7th and done this before i would be thankful if you'd answer <3, btw this is a guided notes)
Answer:
The capacity or power to do work, such as the capacity to move an object (of a given mass) by the application of force. Energy can exist in a variety of forms, such as electrical, mechanical, chemical, thermal, or nuclear, and can be transformed from one form to another.
Explanation:
Energy, in physics, the capacity for doing work. It may exist in potential, kinetic, thermal, electrical, chemical, nuclear, or other various forms. There are, moreover, heat and work—i.e., energy in the process of transfer from one body to another.

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

Plsss I will give brainliest, and 12 points !!
Answer:
One thing that all scientists have in common is that they find problems in the world, and attempt to seek answers to those problems. Everything that scientists do begins with observations, leading to questions.
Let me know if this helps!
While no single scientific method is uniformly followed by all scientists, there are certain common aspects and concepts that scientists share in their search of knowledge and understanding.
These are some examples:
Scientists rely on empirical evidence gathered via observation, experimentation, and measurement.
Systematic and Objective Investigation: Scientists explore and analyse events using systematic and objective approaches.
Scientific discoveries should be repeatable, which means that other researchers should be able to replicate the tests and achieve identical results.
Thus, although scientists' methodologies and approaches differ between fields, these basic principles drive their research and contribute to the collective growth of scientific knowledge.
