Design your own scientific experiment. Your experiment must follow the scientific method and meet the criteria described in the
Volgvan

Answer:

"What seasonings make melt the fastest, garlic, sugar, or pepper?"

Explanation:

this can be a good question because it is highly specific and there are no questions as to what your experiment is

explanations for the scientific method:

1. Make an observation- "different conditions affect the melting of ice such as people salting the roads in winter, this caused me to be curious of what other seasonings might possibly have a similar effect to that of the salt."

2. create a Hypothesis- "I hypothesize that garlic will have the most effect on the melting of the ice because like salt its a more savory seasoning while sugar is more sweet and the reaction would be different and pepper has little flavoring to begin with"

3. test your hypothesis- "this can be done using 3 trials in which 3 pieces of ice are laid onto paper towels and seasoned with 1 teaspoon each of each individual flavoring along with one ice cube that will remain unseasoned (this is our control) we shall then set a timer for 2 minutes and see which ice cube is the most melted"

4. draw conclusions- "this will lead you to the result of the experiment, this would be the seasoning that cause the most effect on the melting process of ice"

Define cell and atom​
Novay_Z [31]

Answer:

Cell: All living organisms are made up of cells, which are the basic building components. Cells also carry the body's genetic material and have the ability to replicate themselves. Cells are made up of several components, each of which serves a particular purpose. Organelles, for example, are specialized structures that perform specific activities within the cell.

Atom: Protons, neutrons, and electrons are the three subatomic particles that make up an atom. The nucleus, which is made up of protons and neutrons, is at the core of the atom, while electrons float around in a tiny cloud above it.

What is the argument against taking persistent vegetative state patients off of life support?
Leviafan [203]

Answer:

An argument could be that there have been many instances where people on life support or in a vegatative state have 'woken' up and gotten better after many years. So, taking someone off life saving machines could be taking away their chance of getting better and their chance of surviving. Since the person is not dead, some may even see it as murder.
