An experiment might not support a hypothesis even if the hypothesis is correct because if the conclusion
What is the meaning of the phrase 'physical properties'?
Measurable attributes of a portion of our observable world is what physical properties are.
Specifically, something which is physical can be observed. Something which is a property also functions as an attribute. In this context, an observable attribute lends itself to being measured and to telling us something informative and useful about the part of the world to which it belongs.

A substantive theory may be constructed within the process of identifying differences and similarities of contextualized instances, and patterns, across and within case studies focused on a similar theme. The content of substantive theory is mainly descriptive, focused on the essence, or substance, of the numerous case instances in a parsimonious relational structure.

What happens when normal cells are grown in a dish containing all the requirements necessary?
Normal cells stop growing when they encounter another cell.
What is a measure of how fast particles are moving?
Speed, measured in meters per second. If you know the mass, you can know its speed from the result of an impact.
A larger impact with an equal mass means a higher speed, a lower speed means less impact.
Where does a germinating dicotyledon seed obtain food for its growth?
A germinating dicotyledon seed obtains food for its growth from the endosperm, a nutrient-rich tissue within the seed that provides energy and nutrients for the developing seedling until it can photosynthesize on its own.

Why were there water droplets inside the jar after burning a candle inside it?
Burning produces carbon dioxide and water; water cools when it reaches the walls and becomes dew.
Does a liquid become a gas when its particles have absorbed enough energy to escape the surface?
Yes, a liquid becomes a gas when its particles have absorbed enough energy to overcome the intermolecular forces holding them together. This allows the particles to escape the surface and become a gas.
Why do bubbles show that this is irreversible change?
Because a gas has been produced and has escaped from the reaction, so you obviously can't put it back again to reverse the reaction.
What are the answers to the barrow county mystery disease?

Carbon typically forms covalent bonds, where it shares electrons with other atoms to achieve a stable electron configuration. Carbon can also form ionic bonds in certain situations, where it gains or loses electrons to bond with other atoms.
