What did Ruthford's Gold Foil Experiment provide evidence for?
The experiment provided evidence for a positively charged bundle in the center of the atom. We now know this to be the nucleus.
What is the purpose of anti bump granules in simple distillation?
The anti-bumbing granules provide many places where bubbles of gas may form as the water boils . The bubbles are small and rise steadily to the surface of the liquid where they burst. Without the granules, fewer but larger bubbles form . they rise and burst with such force that they shake the test tubes which can be very hazardous.
What happens if egg is put to Hcl and then water?
The egg in HCl reacts violently as the calcium carbonate on the outer surface of egg is dissolved. This is what actually happens : The egg in the hydrochloric acid is lighter, because the gas bubbles provide a floatation device, than the acid so it stayed at the top. The bubbles occurred because the calcium carbonate on the egg shell reacted with the acid. Carbon dioxide bubbles are produced, causing the egg to rotate and spin. The carbon dioxide bubbles on top of the eggs break. In the meantime more bubbles are attached to the bottom of the egg. These bubbles now cause the egg to spin and repeat the process. The bubbles attached to the egg also made it less dense. After this experiment, the egg will not have a shell. It will have dissolved. then when you place this egg in water, Osmosis takes place. Well, the egg is 90% water. So now when you keep the egg in water it kind of pushes the egg membrane. Basically, water is flowing into the egg and the egg swells as the water enters it.
What can scientists measure to provide evidence that electrons can move from one energy level to another?
the energy absorbed or released by atoms
What does the term bumping mean in chemistry?
Bumping is a process in which a solvent becomes superheated and then undergoes a sudden release of a large vapor bubble, explosively forcing liquid outside of a flask.You may have tried using boiling chips in organic chemistry lab during a distillation experiment. Boiling chips are made of a porous material and have a nonreactive Teflon coating - they provide nucleation sites (extremely localized budding for gaseous bubbles) so the liquid boils smoothly/more easily. The air bubbles break the surface tension of the liquid being heated and prevent superheating and bumping.An ebulliator can also be lowered into a distillation flask to introduce small air bubbles - this serves the same function as boiling chips.
Which observation would provide indirect evidence that supports a hypothesis that the bubbles are O2?
An increase in bubbles on the plant when it is moved under a brighter light
What is indirect observation?
Indirect observation involves gathering information about a subject through methods other than direct interaction, such as studying their behaviors, activities, or interactions with the environment. It can provide insights into a subject's characteristics or preferences without their knowledge or involvement.
What observation will provide evidence that differentiated cells retain all the genes of developing cells?
Nuclei from mature cells can direct the development of an entire individual.
What does circumstantial evidence mean in terms of Tom's trial?
Circumstantial evidence refers to evidence that suggests a fact is true without directly proving it. In Tom's trial, circumstantial evidence may include witness testimony, physical evidence, or other indirect evidence that may point to Tom's guilt or innocence but does not provide direct proof of his involvement in the crime.

Evidence can prove, or disprove, the case against you.
What does provide evidence for continental drift?
Is there a list? Continental drift is real, so religious fanatics don't provide evidence for continental drift.
How do limestone deposits provide evidence of how plate motions have changed earths surface?

In a court of law who is most likely to provide evidence?
Evidence can be admitted by either side; however, typically, the prosecution is expected to provide proof beyond a reasonable doubt, through the evidence they've obtained.
Does microbiology provide evidence of evolution?
Short answer: yes. Everything we observe about the shape, behaviour and genetics of organisms in all shapes and sizes can and does provide evidence for evolution.
