Since the scientific method states the 5 basic steps list below:
1. Ask a question.
2. Formulate hypothesis.
3. Perform experiments.
4. Collect data.
5. Set conclusions.
They are eligible for any experiment that's why it could be misinterpreted as it was initially stated, nevertheless, science involve more than just one try and when the experiments don't match with the hypothesis, we must propose alternatives to improve the results and of course, go beyond when new researches are being performed.
option B = 0.410 g
The given measurement have five significant figures 41006. this measurement can be rounded to three significant figures i.e, 0.410 g.
All non-zero digits are consider significant figures like 1, 2, 3, 4, 5, 6, 7, 8, 9.
Leading zeros are not consider as a significant figures. e.g. 0.03 in this number only one significant figure present which is 3.
Zero between the non zero digits are consider significant like 104 consist of three significant figures.
The zeros at the right side e.g 2400 are also significant. There are four significant figures are present.
Taking into account the definition of significant figures, the correct answer is option B): the measurement 0.41006 gram, rounded to three significant figures, is expressed as 0.410 g
First of all, you have to know that significant figures are called the set of digits that are known with certainty in a measure. That is, the significant figures of a number are those that have a real meaning and, therefore, provide some information.
Significant figures are the digits of a number that we consider non-null.
To establish the significant figures you must bear in mind that:
In this case, taking into account the previous rules, the correct answer is option B): the measurement 0.41006 gram, rounded to three significant figures, is expressed as 0.410 g
Answer:they run multiple tests to make sure it is a fact that it is right
the answer is :
C) 1003 g
i looked up the answer trust me!!!

The corrects answer are cold and snow clear.
The clouds in the sky indicate that the weather will be cold. The dark cloudiness is because when the cloud absorbs a greater amount of water and the drops are denser, they do not allow the sunlight to filter out and are therefore perceived to be grey or black, indicating the possibility of snow.
Have a nice day!
Answer: the answer, is cold :, snow!
Explanation: “You can tell, that it’s getting darker so it’s going to become snowy and cold! So when it gets cold the sky will be dark ”

Solubility is Affected by pH
The pH of an aqueous solution can affect the solubility of the solute. By changing the pH of the solution, you can change the charge state of the solute.
At pH extremes, the amino acid molecules mostly carry a net charge, thus increasing their solubility in polar solvent. At very low or very high pH, the amino acid molecules have increased charge, thus form more salt bonds with water solvent molecules.
An isoelectric point is the pH at which an amino acid exists as its zwitterion. A zwitterion is the dipolar ionic form of an amino acid. ... If the pH is lower (in acidic conditions) than the isoelectric point then the amino acid acts as a base and accepts a proton at the amino group. This gives it a positive change.
An amino acid is usually more soluble in aqueous solvent at pH extremes than it is at a pH near the isolelectric point of the amino acid. (Note that this does not mean that the amino acid is insoluble at a pH near its pI.)
Which of the following statements correctly explains this phenomenon?
(Select all that apply.)
The neutral charge of an amino acid molecule at its isoelectric point will make the molecule hydrophobic.
At pH extremes, the amino acid molecules mostly carry a net charge, thus increasing their solubility in polar solvent.
At very low or very high pH, the amino acid molecules have increased charge, thus form more salt bonds with water solvent molecules.
At pH values far from the isoelectric point, individual amino acid molecules have greater kinetic energy, thus more readily stay in solution.

Chemicals that do not cause cancer by themselves but can act with another chemical to cause cancer (cocarcinogens). Damage to DNA in cells can lead to cancer. ... Unrepaired DNA damage can lead to mutations, or changes, in genes, and mutations in certain genes can cause cancer. You can also inherit mutations.

Atomic mass is defined as the number of protons and neutrons in an atom, where each proton and neutron has a mass of approximately 1 amu (1.0073 and 1.0087, respectively)
