Answer:
1.Ammonium hydroxide can be found in the bathroom, floor, glass, carpet, metal, upholstery, and all-purpose cleaners as well as starches, disinfectants, and stain treaters. Most household ammonia contains 5 to 10 percent ammonium hydroxide.
2.(a)Electro magnets are used in electric bell, loud speakers, electric motors, telephone diaphragms, electric fan and for sorting scrap metal and for extraction in hospitals
(b)Giant electromagnets are used in cranes to lift machinery, in shipyards for loading and un loading purposes and bulk quantity of iron and steel.
3.Miniature Circuit Breaker or MCB is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by overload or short circuit. Its basic function is to detect a fault condition and interrupt current flow.

5.Both Amoeba and human beings are heterotrophs and derive nutrition from other organisms. Dissimilarity: Human beings have a complex digestive system and different nutrients are digested in separate regions. Amoeba does not have a digestive system and all the nutrients are digested in the food vacuole.
6.(a)The primary functions of the liver are:
Bile production and excretion.
Excretion of bilirubin, cholesterol, hormones, and drugs.
Metabolism of fats, proteins, and carbohydrates.
Enzyme activation.
Storage of glycogen, vitamins, and minerals.
Synthesis of plasma proteins, such as albumin, and clotting factors.
(b)The core function of the human stomach is as an aid to diges- tion. The four key components of gastric digestive function are its function as a reservoir, acid secretion, enzyme secre- tion and its role in gastrointestinal motility.
(c)The small intestine (small bowel) is about 20 feet long and about an inch in diameter. Its job is to absorb most of the nutrients from what we eat and drink. Velvety tissue lines the small intestine, which is divided into the duodenum, jejunum, and ileum
