Sally and Maria hypothesized that earthworms lived only in dark, damp places. They measured a one-meter square in a shady spot near a stream. They dug through the soil and collected earthworms. They collected 43 worms. They repeated the experiment in several locations, sunny and dry included. They found the most worms in the shady, damp plot near the stream. Several other groups of science students carried out the same experiment and got similar results. This is an example of A) bias. B) repetition. C) replication. D) validity.

Answer: Ammonia belongs to Inorganic compounds.
Inorganic compounds are those compounds which do not have C-H bond ( Carbon- Hydrogen bond). The molecular formula of ammonia is . It is also called as Nitrogen hydride. Nitrogen is linked to three hydrogen by the covalent bond. It exists in the gaseous form in its pure state.
Since there is no C-H bond in its molecular formula, therefore it belongs to inorganic compounds.

Final answer:
The autonomic nervous system, divided into the sympathetic and parasympathetic divisions, regulates the functions of internal organs. The sympathetic states prepare the body for intense activities, while the parasympathetic states help the body to rest and regenerate.
Explanation:
The autonomic nervous system regulates many internal organs in our body. It is divided into the sympathetic and parasympathetic divisions that often act in opposition to each other to maintain homeostasis. The sympathetic division is associated with preparing the body for intense, energy-consuming activities, commonly referred to as the 'fight or flight' response. It can increase heart rate, dilate pupils, and slow digestion, among other functions.
On the other hand, the parasympathetic division restores the body to normal functioning after the sympathetic division has been activated. It is associated with relaxing the body, slowing heart rate, constricting pupils, and stimulating digestion, hence its nickname 'rest and digest'. Hence, the functions of internal organs like the heart, lungs, and digestive system are controlled alternately by these two divisions of the autonomic nervous system, depending on the body's needs at the time.
