Density involves the amount of a material in a certain volume. When a material changes phases, it changes in density in a predictable way as the amount of material stays the same but the molecules get farther apart or closer together. Water has solid and liquid states that do not follow these predictions of density in the phases of matter.
What does that mean about the densities of the phases of water?
The solid state is the most dense, followed by the liquid state, then the gas state.
The solid state is more dense than the liquid state.
The liquid state is more dense than the solid state.
The gas state is the most dense, followed by the liquid state, then the solid state.

An environment can support only as many organisms as the available energy, minerals, and oxygen will allow. The term best described by Carrying capacity
Carrying Capacity
It is the average population density or population size of a species below which its number tend to increase and above which its number tend to decrease because of shortage of resources. The carrying capacity is different for each species in a habitat because of that species particular food, shelter, and social requirements.

Because of high increases in populations, some underdeveloped countries are already exceeding their carrying capacity. They cannot produce enough food to support their populations. These regions are undergoing very rapid desert formation. Growing populations contribute to this by clearing forests for agriculture and firewood. Which region in the table is most likely experiencing desert formation? Explain.
Hint: Think about where the population is increasing the most quickly.
Answer:
Africa is most likely experiencing desert formation because it's annual growth rate is the highest of them all.
In the given scenario, Africa is most likely experiencing desert formation as it is having highest growth rate percent.
What is growth rate?The average annual rate of change in population size for a given country, territory, or geographic area over a given time period.
As the given regions are undergoing very rapid desert formation, Africa would go through this process, as it is having highest growth rate.
Thus, the answer is Africa.

Which of the following are the large molecules that are broken down into smaller molecules during digestion?
Answer:
Mechanical digestion can only break up the food particles into smaller pieces. A chemical digestion process called enzymatic hydrolysis can break the bonds holding the molecular 'building blocks' within the food together. For example, proteins are broken down into their 'building block' amino acids.
Explanation:
Fats, proteins, and carbohydrates are macromolecules that are broken down into smaller molecules during digestion.
What is digestion?The term "digestion" describes the process by which food is broken down into smaller pieces that can be absorbed into the bloodstream.
The breakdown of food into smaller bits, known as mechanical digestion, takes place in the mouth. Chemical digestion, on the other hand, takes place in the gastrointestinal tract when the meal is broken down into small molecules by digestive enzymes. Digestion begins from the buccal cavity.
Macromolecules such as fats, carbohydrates, and proteins, are broken down into their monomeric form. Thus, this four are the large molecules broken down into smaller molecules during digestion.

If a car has a mass of 700kg and a driver pushes the car with an acceleration of 0.05m/s/s; what is the force?
Answer:
35 N
Explanation:
The formula to calculate force is:
F= m*a
So, the mass is 700 kg, and the acceleration is 0.05 m/s.
Simply multiply 700 kg* 0.05 m/s and you get 35 N.
The reason why it is newtons(N) is because that is what force is measured in.
