A) circulatory system and immune system
B) digestive system and excretory system
C) circulatory system and digestive system
D) respiratory system and excretory system
Answers
Answer: A) circulatory system and immune system
Circulatory system and digestive system are the body systems which will help these cells get the energy they need.
What is Digestive system?
These are parts of the body which are involved in the breakdown of food to form energy and other compounds.
Circulatory system on the other hand ensures the nutrients are transported to other parts of the body which is why option C was chosen.

Can someone please explain the cause and effect between the rearrangement of atoms and molecules in a chemical reaction and the different properties that the products have from the reactants.
Answers
Answer:
In a chemical reaction, the atoms and molecules that interact with each other are called reactants. ... No new atoms are created, and no atoms are destroyed. In a chemical reaction, reactants contact each other, bonds between atoms in the reactants are broken, and atoms rearrange and form new bonds to make the products.

I'll mark brainlyest to whoever has the best answer and give them 50 points for helping me.
Answers
The Zinc carbon batteries, are a reliable source of power for appliances that consume little energy. Some examples are: remote controls for televisions, clocks, and smoke detectors. A reason that you should use the Zinc carbon batteries is for, the low energy consumption. This will lead to being able to use the appliances for a longer time for the same money.
The difference between the batteries is the capacity. Because of composition, an alkaline battery, delivers more energy than a zinc carbon battery.
The only downside is that, both batteries need to be used in different appliances.

5. surface tension
what do you mean by cohesion ?cohesion is an attractive force of measure where molecules are stick to each other and it is caused by cohesive force between like molecules.
It is an intrinsic property of a molecule, derived by its shape, structure, and electric charge distribution.
When cohesive molecules are become closer to each other, the electrical attraction between these molecule holds them together.
This forces are responsible for surface tension. For example mercury is a cohesive substance, strongly attracted to each other, bead together, sticks to itself when it flows.
When cohesion and adhesion combinedly work, it will lead to capillary action.
Hence, when water climbs up the interior of a thin glass tube or the stem of a plant, Cohesion holds the water together and adhesion helps the water molecules stick to glass.
