What Is a Gastrovascular Cavity?
The gastrovascular cavity is a structure found in primitive animal phyla. It is responsible for both the digestion of food and the transport of nutrients throughout the body. The cavity has only one opening to the environment. Food goes in and waste comes out that same opening, making it a two-way digestive tract.
By contrast, organisms that have a mouth on one end with an anus on the other end have a one-way digestive tract, called an alimentary canal. Food goes in the mouth, while waste comes out the anus.
Answer:
he Schachter-Singer Theory, also known as the Two-Factor theory of emotion, states that 2 factors are needed to experience emotion. First, environmental stimuli elicits a physiological response. Second, we cognitively appraise this physiological activity, and try to give it the correct label.
Explanation:
Answer:
D. "Sucralfate has a moderate acid-neutralizing capacity."
Explanation:
Sucralfate is used to treat peptic ulcers in combination with other drugs. It reacts with hydrochloric acid in the stomach and forms a viscous material by mechanism of cross-linking. This material has paste like consistency and forms a protective barrier on ulcers by attaching with the proteins on ulcer surface. The barrier does not allow further harm due to action of acid on ulcer. It also does not allow the diffusion of hydrogen ions back into stomach cells. But it is not involved in neutralizing the acid and increasing the pH of stomach. It can show minor antacid activity but that it not considered clinically significant.
Inertia refers to the resistance of an object (for example, a car) to any change in its direction or velocity. For that reason, it is imperative to drive within the permitted speed limits.
- A car cannot instantaneity change its speed and/or direction of motion due to inertia, leading to different transportation injuries.
- It has been shown that a five percent (5%) increase in car velocity leads to a 20% increase in fatal crashes.
- It is for that reason that is imperative to drive within the permitted speed limits.
In consequence, the statement speeding increases the distance needed to be able to stop the car and limits the reaction time needed to avoid a potential collision is TRUE.
