<h3>
Answer:</h3>
512 mL
<h3>
Explanation:</h3>
We are given;
- A cube with a side 80 mm long or 8 cm long
We are required to calculate the volume;
- Volume refers to the amount of space an object occupies.
- To calculate the volume of a cube we get the cube of its side;
- That is, volume of the cube = l³
Therefore;
Volume = (8 cm)³
= 512 cm³
But; 1 cm³ = 1 mL
Therefore, the volume of the cube in mL is 512 mL
I believe the answer is A. 40 mL

Answer:
Explanation:
All chemical changes requires a substantial amount of energy. Depending on the type of reaction, the energy of reactants and products differs.
In an exothermic chemical change where heat is always given off to the surroundings, the energy of the product is less than that of reactants.
For endothermic changes, the surrounding becomes colder at the end of the reaction. This implies that the heat energy of the product is higher than that of the reactants.
Villi: The folds form numerous tiny projections which stick out into the open space inside your small intestine (or lumen), and are covered with cells that help absorb nutrients from the food that passes through. Microvilli: The cells on the villi are packed full of tiny hairlike structures called microvilli. The function of the plicae circulares, the villi, and the microvilli is to increase the amount of surface area available for the absorption of nutrients. Each villus transports nutrients to a network of capillaries and fine lymphatic vessels called lacteals close to its surface.
