Answer:
aby steps in science occur as small bits of evidence gradually accumulate. The accumulating evidence lets scientists refine and expand on earlier ideas
Explanation:
The benefit to having baby steps in science occurs as small bits of evidence accumulate is which lets scientists refine and expand on earlier ideas. The correct option is a.
What is science?Science is the subject of learning facts and ideas about the earth and other natural things present on the earth. It constitutes the phenomena and the acts behind the happening of things. They search and contribute to the reason behind something natural.
Science works based on evidence and proof. It describes the theories and facts behind natural things. So taking baby steps in science is essential to make it clear that no facts are left behind. Science always changes because of the changing of things.
Thus, the correct option is a. let scientists refine and expand on earlier ideas.

Find the density in g/cm^3 of chalk, if 6.356 g occupy 2.56 cm^3
Answers
Answer:
Density = 2.48 g/cm³Explanation:
The density of a substance can be found by using the formula
[tex]Density = \frac{mass}{volume} [/tex]
From the question
mass = 6.356 g
volume = 2.56 cm³
Substitute the values into the above formula and solve.
That's
[tex]Density = \frac{6.356}{2.56} \\ = 2.4828125[/tex]
We have the final answer as
Density = 2.48 g/cm³

PLZ HELPP Cynthia sees that most of the ice in her iced tea has melted. Assuming the water and the ice are at the same temperature, what happened to the particles in her ice? A.The particles have a much greater amount of kinetic energy than before. B.The particles have the same amount of kinetic energy but no longer vibrate in place. C.The particles have had their kinetic energy converted into thermal energy. D.The particles have a higher temperature than before and are moving more freely.
Answers
Answer:
The most correct option here is D
Explanation:
The difference between a solid (ice) and a liquid (water)/gas (steam) is that the particles in a solid is tightly packed (and do not move) as against the particles in liquid which moves quite freely or those in gases that move very freely.
When a solid (for example ice) is subjected to heat, it's particles receives the heat energy, hence have a higher temperature, and starts moving from its compact position which turns the solid into liquid. This was what happened to the ice in Cynthia's iced tea. The ice got/absorbed an increased temperature from the surrounding tea and it's particles began to move (more freely) thereby causing the ice to melt.

D

Answers
Answer:
ITS A. (Give me brainliest!!)
When a glass or a watermelon is moved, the volume stays the same as they are in a fixed shape and the volume of a solid state. Option A correct.
What is the solid-state?A solid-state is a state of matter in which the molecules of matter are closely packed with each other with the maximum molecular force of attraction for a fixed shape.
Glass and watermelon are fixed in shape as they are made before and volume is also fixed and the molecules are fixed in definite shape and the volume cannot be changed.
Therefore, Option A correct. When a glass or a watermelon is moved, the volume stays the same as they are in a fixed shape and the volume of a solid state.

significant figure of 87 000 ms
Answers
Answer:
2 significant figures.
Explanation:
Significant Figures Rules:
1. Anything that isn't a zero is a sig fig
2. If a decimal point comes after the ones digit, everything before the decimal is counted as sig fig (i.e 2000. would be 4 sig figs).
3. If we are dealing with small decimals, the zero before and after the decimal (i.e 0.002) is a placeholder and is not counted as sig figs.
4. Any zeros between 2 significant digits is considered in sig figs (i.e 2002 would be 4 sig figs)
Since we are dealing with 87000, we see that we have no decimal point. That means our only sig figs are 8 and 7, which equals 2 sig figs.

Explanation:
A salt is made up of homogeneous particles while sand is made up of heterogeneous particles. Salt is a crystalline substance while sand is a coarse substance.
If salt and sand are mixed with water, salt forms a solution with water, hence, salt cannot be caught on filter paper. However, sand does not form any chemical specie with water hence it is caught on the filter paper as a solid.

If you find the mass of a sample to be 42.1 g and the actual mass is 42.0 g. What wold be the percent error
Answers
Answer:
0.24%
Explanation:
The following data were obtained from the question:
Measured value = 42.1 g
Actual value = 42 g
Percentage error =?
Percentage error can be obtained by using the following formula:
Percentage error = |Measured value – Actual value | / Actual value × 100
With the above formula, we can obtain the percentage error as follow:
Measured value = 42.1 g
Actual value = 42 g
Percentage error =?
Percentage error = |42.1 – 42| / 42 × 100
Percentage error = 0.1/42 × 100
Percentage error = 10/42
Percentage error = 0.24%
Therefore, the percentage error is 0.24%
Why is the following molecule nonpolar and hydrophobic?
Answers
Answer: the answer is not the glycerol molecule in fats contains a carboxyl group
The given molecule is nonpolar and hydrophobic because there is an unequal distribution of hydrogen and oxygen atoms. Thus, the correct option for this question is D.
What is a Hydrophobic molecule?A Hydrophobic molecule may be defined as a type of molecule that is interestingly repelled from a mass of water. It is typically not soluble in water. These molecules are always repelled away from water contact.
When there is an equal distribution of hydrogen and oxygen atoms delivered, the constructed molecule is polar and hydrophilic in nature. This is because the partial positive charge on the hydrogen atom attracts the partial negative charge of oxygen and makes the molecule attracted to the water.
Therefore, there is an unequal distribution of hydrogen and oxygen atoms is a statement that is responsible for a molecule to be nonpolar and hydrophobic. Thus, the correct option for this question is D.

C) Carla participated in an artistic activity, while Maurice participated in a scientific activity.
Explanation:
Scientific activities involve making observations, which ultimately leads to the series of steps that aims at solving the observed problem or answering a question that arises from the problem. This is the case of Maurice who is observing and recording information about ants in order to solve a curiosity (about what they feed on).
However, on the other hand, Carla is given a pictorial representation of the ants and what they carry. It is not based on curiosity or to answer a question about the ants but rather for decoration or aesthetic purposes, which is what makes her activity artistic.

C. The test variable (independent variable) and outcome variable (dependent variable) have no affect on each other.
Explanation:
The test variable (independent variable) and the outcome variable (dependent variable) have no effect on each other. Hence, option C is correct.
What is an independent variable?The independent variable can be altered, manipulated and changed in an experimental study.
Researchers often measure independent and dependent variables in studies to test cause-and-effect relationships.
The independent variable is the reason or cause. Its value is independent of other variables.
The dependent variable is the outcome whose values depend on changes in the independent variable.
Hence, option C is correct.
