Answer: A. water within a pan is heated and flows in a circular path.
Explanation: Convection is a type of heat transfer that occurs in liquids and gases. Convection occurs when there is a contrast in temperature between two parts of a liquid or gas. The hot part of a fluid rises above, and the cooler part sinks to the bottom resulting to circular motion of the fluid.
B or c
It’s kinda confusing
Answer:
Genes are located in the CHROMOSOME
Explanation:
Genes are contained in chromosomes, which are in the cell nucleus. A chromosome contains hundreds to thousands of genes. Every normal human cell contains 23 pairs of chromosomes, for a total of 46 chromosomes. A trait is any gene-determined characteristic and is often determined by more than one gene.
Answer:

Explanation:
For this case we know that the charge associated to the transferred electrons of the small spark is
and we want to find the number of electrons transferred.
From the properties of matter we know that the charge of the electron is

And we know that the total charge is given by this expression:

Where Q represent the charge, n the number of electrons and e the charge of the electron.
If we solve for n we got:

And replacing we got:
