B. all of the above.
C a measure of how tightly the particles in a substance are packed together
D. the mass of an object divided by its volume
The statement that describes density is:
It is a scalar magnitude that allows us to measure the amount of mass in a certain volume of a substance.
Therefore, we can conclude that density refers to the relationship between the mass of a substance (or of a body) and its volume.

Answer:
C
Explanation: Density is not the weight or matter it is the amount of particles that are packed into a set area. For example a dumbbell is more dense than styrofoam even though styrofoam may take up more space.
Endothermic reaction
Exothermic reaction
Endothermic reaction
An endothermic reaction is those reactions that take up energy from the environment as that proceeds. The opposite is an exothermic reaction that gives off energy to the environment.
Explanation:
When cooking an egg you require energy to break down the interactions between the protein chains and atoms of the raw egg so they are rearranged into a cooked egg. This is akin to the denaturing of proteins. Cooking food helps ease their digestion. Because we need energy to break down the interactions and bonds of the proteins in the egg this is why we use fire in cooking. This is, therefore, an endothermic reaction.

The kingdom Animalia, which belongs to the Eukarya domain, is known for having organisms with cells that do not have cell walls. Other kingdoms, like Plantae and Fungi, typically have cell walls.
The kingdom known for containing organisms with cells that lack cell walls is the Animalia kingdom which exists within the Eukarya domain. In the classification of life, three main domains exist: Bacteria, Archaea, and Eukarya. The first two mainly include prokaryotic organisms which usually have cell walls. The Eukarya domain includes four kingdoms: Animalia, Plantae, Fungi, and Protista. Among these, it's typical for Plantae and Fungi to exhibit cell walls. Conversely, Animalia comprised of animals, do not have cell walls surrounding their cells. Their cells are surrounded by a plasma membrane which offers flexibility and aids in movement and interaction with the environment. This characteristic is one of the key distinguishers of the Animalia kingdom from other kingdoms.

The correct answer is Camouflage
The technique which is used by the animals to protect themselves from the predators. They prey usually changes the color of the body and match it to the surrounding environment so that the predators cannot recognize it.
Prey usually use this technique to protect themselves from the prey and helps in surviving.
Example: Chameleons, octopus et cetera.
B. Traction
C. Suspension
D. Abrasion
Which answer choice is the correct one? Thank you.
Answer: B. Traction
Traction is a geological process in which a mechanical force transports larger and heavier rocks by sliding and rolling along the substratum. Traction occurs by water erosion. It results in the movement or transportation of large rocks stones or boulders, which are otherwise settled at the bottom, by the force exerted by the water current. These rocks, stones or boulders gets displaced from their sites and attains a rolling movement due to fast flowing water current.
