Answer:
The correct answer is - a density independent factor.
Explanation:
Any external cause or change that leads to the change in the size of a population regardless of the density of the particular population known as a density independent factor in ecology.
Density independent factors are the factors that are not affected by the size of the population size of the species such as weather, climate and natural disasters.
Thus, the correct answer is - a density independent factor.

Answer:
A worker bee defends the hive while the queen bee lays eggs
A prairie dog barks to alert family members when it spots a predator
Explanation:
Just like people, some animals live in communities, where each of them plays a certain role. For those animals, we can say that they live in a social hierarchy.
Examples that describe something like this are the second and fourth ones.
In a hive, there are different types of bees: workers, drones, and a queen. Each of them plays their role, which makes their hive function properly.
Prairie dogs are another example of species that live in large communities. Since they are small and have numerous predators, they rely on each other for protection. They do this by barking whenever they spot a predator, this way alerting other members of their community.
The rest of the statements simply tell about how some species live without mentioning their social life. This is why they are incorrect.
Animals use protein for several roles in the body, such as building and repairing muscles and other body tissues. It is needed to form new skin cells, grow hair, build muscle tissue, and more. It also assists in creating body chemicals like hormones and enzymes that are needed for normal function. It provides energy (like carbohydrates do) and keeps the immune system strong.
The acids have more H+ while bases have more OH-. About pH, typically under room temperature, when a solution has pH<7, it is acid. When pH>7, it is base. And when pH=7, it is neutral.
