Do gram-positive cells carry a net positive charge?
Gram-positive does not refer to a positive charge, but to the purple color of the stain. Gram-negative bacteria do not retain the purple dye and are instead red in color.
In the lugols solution test what color is a positive test?
intense blue or black
What is the charge of the center of an atom?
Protons have a positive charge, neutrons are neutral. Gluons are neutral (with respect to electromagnetic charge; they do carry color charge, but that's complicated and comes in 8 different types). Electrons are negative. Quarks have varying charges: up quarks are +2/3, down quarks are -1/3 (quarks also have color charge, but only 3 different kinds).
What is the color of hot service wires feeding the electric panel?
they can be any color except for white, gray or green.
Name the particle of matter that makes up protons and neutrons?
Quarks are the main constituent of matter. It takes two up (posistively charged, stage I Fermions) and one down (Negatively charged Stage I Fermion) quark, the up having electric charge +2/3 and the down having electric charge -1/3, one with red color charge, one with green color charge, and one with blue color charge, to make a proton. (Electric charge +1)(all the Stage I Quarks have spin 1/2) Not sure what makes a neutron...

What is a particle with no charge called?
Neutral (ba-dump-tsssh!). There are a number of particles with no electric charge, including but not limited to"NeutronsNeutrinos (all varieties)PhotonsGluons (gluons carry "color charge", but not electric charge)Gravitons (provided they exist; the jury is still out on that)
What color is negative or positive on alligator clips?
