Answer:
ATP molecules
Explanation:
Density centrifugation is a method that separates components of a sample on the basis of their density or density gradient.
During centrifugation the sample will be layered according to their density and that is the principle of density centrifugation.
When centrifuging a sample containing homogenized cells. ATP molecules will be found at the top of the centrifugation gradient due to having a lighter density compared to the rest of the molecules.
Answer:
The answer is organic
Explanation:
Used from plants and animal product composted.
Answer: Option D.
Crystalline and rigid.
Explanation:
When liquid freezes to ice, it becomes solid and this is crystalline and rigid because a solids for crystals which means solid atoms, molecules or ions are orderly arranged in structures which form of crystal lattice in all sides. The structure of solid becomes rigid , it does not take the container shape like liquid and it does not expand also like liquid. it volumes reduces.
Passive
Diffusion and Osmosis are both examples of passive transport.
Answer:
Motion is defined as phenomenon in which an object move from one place to another over a time.
Generally there are four types of motion: Linear, rotary, reciprocating and oscillating.
Linear motion: In this motion an object moves in a straight line. for example: an athlete running in a straight line.
Rotary motion: In this motion an object moves around an axis. For example: Wheel.
Reciprocating motion: In this motion an object moves in a continuous up and down motion or back-and-forth motion. For example: piston.
Oscillating motion: In this motion an object moves in a swinging motion (backwards and forwards) on an axis. For example: Pendulum.
