If an atom has 17 protons, 14 neutrons, and 19 electrons, what is the atom's electrical charge?

Negative

Explanation:

Protons have a positive electrical charge and electrons have a negative electrical charge. One proton's charge is the same "strength" as one electron's charge so since there are two more electrons, it is a negative charge.

Say there were two protons and one electron. It would be a positive charge. Now I ask, if there are 43 electrons and 43 protons, would it be positive or negative? Trick question! Neither, because they cancel each other out.

it enhances antibody production by t cells of the adaptive immune system.

hope i'm right

explanation:

ecological efficiency: % of usable energy transferred as

biomass from one trophic level to the next typical is 10% efficient (90% of

energy is lost),is diagramed as the pyramid of energy flow. then osprey eagle

are tertiary consumer and the shrimp are primary consumer, so to balance

mass of shrimp (1/0.1) / 0.1 = 100 kg
