explanation: the ones that are the deepest are the oldest
Answer:
Option =C each mouse in the study has brown ears.
Explanation:
Qualitative:
Qualitative properties are those that can be only observed but not measured in numerical values. These are observed through senses: touch, sight, smell, taste and hear.
For example:
Color, odor, brittleness, taste etc.
Quantitative:
Quantitative properties can be measured in numerical values.
For example:
Melting point, boiling point, conductivity, viscosity, density, hardness and solubility.
In short we can say that qualitative is a measure of quality while the quantitative is a measure of quantity.
The higher levels of gravity put on an object the more weight the object has. For example someone who weighs say 100 lbs would weigh more if higher amounts of gravity would be applied to them. And less if less gravity was applied. But larger objects will automatically have more gravity applied to them than something smaller due to the gravitational pull needing to pull harder to keep the object to the planet's surface. Hope this helps! :)
All of them are properties of compounds except III.
for I, compounds are chemically combined together, so to separate them, we must use chemical methods like electrolysis or applying heat. These requires large amount of energy.
For II, they're always fixed. For example, in water (H2O), the ratio of hydrogen and oxygen is always 1:8 in mass. If there's some extra added, the substance becomes mixture instead of compounds.
For IV, after you chemically combined elements or compounds together, their properties are completely different. For example, iron can be attracted to magnets, but iron II sulphide does not.
