The chemical formula of ammonium phosphate is (NH4)3PO4. There is 3*4=12 Hydrogen atom in one molecule ammonium phosphate. The total mass of one molecule is (14+4)*3+31+16*4=149. The mass of hydrogen atoms in one molecule is 3*4=12. So the mass percent of hydrogen is 12/149*100%=8.05%

Indigenous Information System (IKS) is the body of knowledge that communities have accumulated over many generations as a result of their interactions with the environment.

<h3>Indigenous Knowledge System (IKS): What is it?</h3>

The technological, economic, philosophical, educational, and governing systems are all included in the indigenous knowledge system.

Prior to the development of the contemporary scientific knowledge system, indigenous societies established their own knowledge, which is included in indigenous knowledge systems (IKS).

Acupuncture from China is an illustration of IKS. Through the preservation and wise use of biodiversity, it may significantly advance sustainable development.

There is a definite need to preserve these systems, acknowledge their worth, and stop their destruction in order to strengthen indigenous knowledge practices and cultures.

Homeostatic regulation usually involves a(n) ________ that detects a particular stimulus, and a(n) ________ that responds to the
geniusboy [140]

Answer:

c) receptor; control center; effector.

Explanation:

Homeostasis maintains the internal body conditions almost constant. It includes specific cells that sense any deviations of internal or external conditions from the normal range. These cells are called receptors. The sensory information from the receptors is delivered to the control center. The central nervous system mainly serves as a control system wherein sensory information from the receptors is processed. The control center commands muscles and/or glands to perform desired responses to restore the homeostasis. Here, muscles and glands serve as effectors.

For example, thermoreceptors sense the rise of body temperature and the brain (control center) commands sweat glands (effectors) to produce sweat.
