Answer:

The correct answer is: D) Facts can be scientifically tested.

Explanation:

An opinion is, by definition, a judgment about something that is not based on facts (for example, if you prefer a certain music genre, that is an opinion). Therefore it cannot be scientifically tested. Option A is false.

Scientific theories are observations based on data that are supported by the scientific community and the general public, but most of the time those theories cannot be fully proved yet, so many years or centuries later, those theories can be debunked thanks to new theories and discoveries. Option B is false.

There are many things that scientists do not know because there is a limit to the research that can be done with our current technology, and there are many things that do not have a scientific explanation yet. So no, scientists haven't learned all they'll ever know about science. Option C is false.

Facts CAN be scientifically tested because they are proven to be true.

Can parent's go too far in supporting their children's dreams

motikmotik

Yes, of course! They may not always realize that instead of helping sometimes they're harming. They could push their child into a school that can help them for the future even though they want to try a different school. They can annoy their child and they'll get sick of it and lose interest in their subject.

A punnet square can be described as a diagram which is made to predict the genotype as well as the phenotypes of the offsprings of a cross.

To study the epistatis nature of the pigmentation in bear, a punnet square was made and the results of the punnet square are shown above.

The results of the punnet square show that the cross between two bears will have the chances of producing 9/16 black bears, 3/16 brown bears and 4/16 white bears.

How do we determine a middle atom without looking at electronegativity?

IgorLugansk [536]

Answer:

An atom's electronegativity gets higher as you move up in the periodic table. Thus, the atoms in the top right have the highest electronegativities and the atoms in the bottom left have the lowest ones.
