Complete Question:
Which of the following might stimulate the cephalic phase of gastric secretion?
A. stomach distention
B. the production of saliva
C. the thought of food
D. the production and secretion of gastrin.
Answer:
C. the thought of food
Explanation:
Gastric secretion usually occurs in three different phases, namely;
- Cephalic
- Gastric
- Intestinal
The thought of food usually stimulate the cephalic phase of gastric secretion in organisms. The presence of lipids or low pH inhibits Gastric secretion during the intestinal phase.
True.
The earth is made of several subsystems or spheres that interact to form a complex and continuously changing (dynamic) state that is termed as the earth system.
Even though the earth system is a closed system, it self regulates through the subsystems such as the water cycle and carbon cycle.
The earth system is characterized by numerous overlapping cycles in which matter is recycled over and over again. Cycles involve multiple spheres and systems interactions. Humans impact and are impacted by the cycles in various ways.
The statement that is true is active transport moves against the concentration gradient.
<h3>WHAT IS ACTIVE TRANSPORT</h3>
Active transport is one of the two types of cellular transport that involves the movement of molecules against a concentration gradient.
This moves that movement occurs from a region of lower concentration to a region of higher concentration. Since movement is against a concentration gradient, it involves input of energy (ATP).
Therefore, the statement that is true is active transport moves against the concentration gradient.

The answer I would say is A.
The sun doesn’t make water
And electricity doesn’t come from the water cycle.
