Are there any minerals in distilled water?
These waters are similar but not identical: - the method of preparation is different - distilled water contain some minor inorganic impurities but don't contain any organic contaminants - demineralized water contain some traces of inorganic impurities but can contain minor organic contaminants
Why conductivity of distilled water is measured as a control?
Controls must be of identical composition in order to avoid affecting the outcome of an experiment. Tap water, demineralized water, rain water, lake water, etc., all have different compositions depending on the environmental conditions where they originate. Distilled water is universally the same no matter where it is made, so long as the container is sterile.
Distilled filtered and purified water is considered a mixture element or compound?
This is a compound, because it is made up of identical molecules, therefore is not a mixture, and each molecule contains two distinct elements, hydrogen and oxygen.
How are compound different from the elements that make them?
Simply put, an element is made up of identical atoms, and a compound is made up of non identical atoms. If I am wrong, blame my science teacher.
Which natural polymers are like a train with identical freight cars and which are like a train with a mixture of different cars?
Cellulose is a natural polymer with thousands of identical sugar molecules linked together.Protein would be a like a train with different freight cars since it has many different amino acids linked together.

Antonym of identical?
Identical means the same so an antonym for identical is different.
Are the cells from the end of mitosis identical or different?
they are identical
Is distilled ethanol similar to pure ethanol?
A) They are [CH3-CHOH] identical; and B) the distillation process is what transforms ethanol into eventually a pure form.
When two alleles of a pair are identical it is a condition if the two alleles are different this is a condition?
When identical: homozygous. when different: heterozygous.
What can you conclude from seeing identical containers with identical fish in them but with different volume of water in each container?
The one with the greater surface area would have more oxygen available to the fish. The one with the greater volume has a fixed amount of oxygen that can be dissolved in a given amount. The one with the greater surface area has more oxygen available over time.
What would distinguish even an identical twin from its sibling?
Fingerprints are different in identical twins.
What happen when identical objects are dropped under different gravitational conditions?
when you drop an identical object in different gravitational conditions it will not have a similar acceleration because the gravity are different.
What would make the volume of 3 identical marbles different?
If the marbles are identical, the volume is the same. If you want, you can use different units and it looks like the volume is different.
How identical twins can be different when they have the same DNA?
Because they separated into separate beings early in the cell division process. After that, a quadrillion factors are involved in the minuscule differences all along the development process. This is how they become different people.
What do you call identical twins that develop from two different eggs that are fertilized by different sperm?
That isn't possible: if the twins are from two different eggs, fertilized by different sperm, then they will not be identical. It's genetically impossible.
Differences between identical and fraternal?
identical twins are from the same egg cell that split, but ferternal twins are from 2 entirely different fertilized egg cells. Thus identical look the same and ferternal can look entirely different.
