Hello,
I believe the answer is C. A and B say that it would help to change it but when we think about it data and opinions are not what people use to change a curriculum or program. Mainly they use surveys, which they didn't use here. Option D doesn't make any sense, data doesn't complement a program it supports some sort of theory which leads us to C. C is the only option where they use the data for effectiveness. Hope this helps!
Okay so just add all of them up the fine the x and the y and d the times that by the size of yiurn four head
Explanation:
A cation is a positively charged ion.
An anion is a negatively charged ion.
- In a cation, electrons are usually lost
- In an anion, electrons are usually gained.
In an atom, the balance between the number of protons and electrons determine whether they become an anion or cation.
Protons are positively charged particles.
Electrons are negatively charged
When an atom gains electrons, the number of electrons becomes more than that of protons. This leaves a net negative charge on the atom and it makes an anion.
When an atom loses electrons, the number of protons becomes more than that of electrons. This leaves a net positive charge on the atom and makes a cation.
