If you shake sugar and sand in a test tube it makes a mixture.
Engineers are trying to improve a race car. Their goal is to increase the acceleration of the car using the same engine. The change that shows the best application of Newton’s laws of motion to achieve this goal is - option D - decreasing the mass of the car.
When the mass of the car will be less, it will automatically accelerate to higher speed as lighter things move faster than heavier things.
A claim refers to an assert or state that something is the case, generally without any proof or evidence. It can also be defined as a proclamation of the truth of something, generally one, which is in doubt or is uncertain.
On the other hand, a scientific claim refers to a statement about the outcomes of the experiment, which is supported by proofs collected at the time of experiment and reasoning that illustrates that how the proof is associated with the claim.
Answer:
The living organisms must not reach equilibrium in the concentration of oxygen and carbon dioxide so that the Exchange of gases continues . Otherwise respiration and photosynthesis will stop.
Explanation:
- Gases move along the concentration gradient i.e. from their higher concentration to lower concetration.
- If living organisms reach a equilibrium of carbon dioxide and oxygen concentration, then The gases will not move in and out of the cells.
- This is because at state of equilibrium the concentration of gases on both side become equal and the movement completely ceases.
- If gaseous exchange in the body stops the process of respiration and photosynthesis in Plants and respiration in animal will completely stop.
It represent a food chain one goes into the other which goes into the other which goes into the other.
