atom is made up of 3 particles protons(positive charge), neutrons(neutral in charge), electrons (negative in charge). proton and neutrons are found in core of atom and form atomic weight of the molecule and electrons moves in shells around core.
example - sodium have 11 protons, 12 neutrons and 11 electrons.
answer is b
Explanation:
aa in the anaphase of cell division crossing over and random assortment of genes happen so the genes are getting mixed up together
Answer:
D) the motion of its particles increases
Explanation:
When heat is added to a solid substance, the particles in the solid gains kinetic energy and the motion of the particles increases.
Answer:
Other variables that could have been taken into account are size, variability of shape in its wings and degree of darkening in its wings.
Explanation:
Of the three named variables, I believe that the degree of darkening is the most important since in this way we can realize the association of its color with environmental pollution, and thus be able to look for a cause-effect relationship.
1. New technology is developed that provides more information about the theory.
2. New experimental methods are designed to test a theory.
3. A single experiment produces results that differ from all previous experiments.
im not sure about #3 but it could be it
