Remember that a controlled variable is a variable that stays the same thoughout the experiment.
it wouldn't be a. because two different wires were used
the final length of the wax would be your dependent variable, so it wouldn't be c.
the thermal conductivity is the independent variable so it isn't d.
the original length of the wax was the same for both.
So B is your answer.
The life cycle stages of a plant would be seeds → germination→growth→maturity→pollination→fertilisation→seeds etc etc.
so I would say the life cycle stages not found in animals would be either pollination or germination.
Inherited genetic factors : hope it helps
A, B, and C. Luster is the light and how light reflects off of it, right?
So, in that case, a non metallic mineral, (think coal) wouldn’t shine much. A metallic mineral would shine, because it’s metal. And something that’s shiny obviously shines.
Go with A B and C.
Enzymes bind with chemical reactants called substrates. There may be one or more substrates for each type of enzyme, depending on the particular chemical reaction. In some reactions, a single-reactant substrate is broken down into multiple products.
