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.
Answer:
water-vascular system
Explanation:
Echinoderms exhibit several unique features and the presence of a water vascular system is one of them. The water vascular system of these organisms consists of a network of fluid-filled canals and chambers. The marine water enters and exits the system through an opening. This system functions as a hydrostatic skeleton during locomotion.
Tube feet of these organisms are filled with fluid as water enters into them via the canals of the water vascular system lead to them. This inflates the tube feet and serve in locomotion. The water entering through the water vascular system also brings in dissolved oxygen and food particles into the body.

Answer:
a. The initial concentration of the substrate
Explanation:
If the researcher keeps the initial concentration of the substrate constant, it will give room to compare the reaction rates under different environmental conditions. The reaction rates will assist the researcher by providing the researcher with the necessary and important information about the enzyme's function in different environments.
Exponential growth then logistic growth as it levels off due to carrying capacity
