Plants called sundews have rounded green leaves with many hair-like structures. The ends of these structures contain enzymes in a sticky liquid that looks like nectar or moisture, as shown in the picture. The hairs do not react to dust or nonliving material but will bend inward when insects get caught in the sticky liquid. Sundews digest trapped insects over a period of a few days.
Based on this information, what function do the specialized leaves of sundews perform?

During the final stages of human gestation, receptors for the hormone oxytocin increase on the smooth muscle cells of the uterus. The release of oxytocin during labor stimulates the smooth muscle tissue in the wall of the uterus. The vigorous contraction of the uterine smooth muscle helps push the baby through the birth canal so that delivery can occur.
This process involves the interaction of which organ systems?
Coracias garrulus is a blue bird with an orange-brown back. The offspring of this bird have an effective defense mechanism.
The young birds vomit and cover themselves in a foul-smelling orange liquid when they sense a threat by predators.

The system signals the bird to dangers in their environment and the system helps produce the vomit it uses as a defense.

The fuzzy millipede, Polyxenus fasciculatus, is found in Texas and is preyed upon by most species of ants. To protect itself against the ants, it ejects fibers from its skin found in tufts located at the tail end of its body. The tufts have hooks at the tips and barbs along their length that lock and interlink with the ant's setae, small hairs that cover the body of the ant.
When an ant attacks, the millipede flexes its back end toward the ant and wipes the tufts against it. As the ant attempts to remove the tufts, it entangles itself more, becoming immobilized (cannot move).
Which two systems most directly interact in the fuzzy millipede's defense against ants?

Both the respiratory system and the digestive system involve the uptake of necessary molecules from an animal's surroundings. Alveoli are tiny sacs that aid in the exchange of carbon dioxide and oxygen in the lungs. Intestinal villi are tiny projections along the lining of the intestines used to take in nutrients from food passing through.
Which system must interact with the respiratory and digestive systems to transport gases and nutrients throughout the body?
