Explanation: Electrons, protons and neutrons basically make an atom.
Neutron has no charge - electrically neutral
Protron carries a positive charge
Electron carries a negative charge.
The gain or loss of electrons determines whether an object becomes positively or negatively charged. If there is gain in electron, object becomes negatively charged; if otherwise, it becomes positively charged.
So, it is a function of electron transfer.
The answer is option B
Each element absorbs light at specific wavelengths unique to that atom. When astronomers look at an object's spectrum, they can determine its composition based on these wavelengths. The most common method astronomers use to determine the composition of stars, planets, and other objects is spectroscopy.
I would say "A"
Muscles are in pairs called "antagonistic muscles." Let's take the human elbow joint as an example from the diagram. The elbow joint has 2 muscles; triceps and biceps. These 2 muscles help raise your forearm up or down. In the diagram, it shows an arrow going up which represents that your forearm is being raised. To raise, your biceps contract and your triceps relax. Its the opposite when you lower yopur forearm. To lower, your biceps relax and your triceps contract.
Best of Luck!
