20. Measuring about 20 feet (6 meters) in length, the small intestine is where the major digestion and absorption of nutrients take place. These nutrients are taken into the bloodstream, via millions of tiny, fingerlike projections called villi, and transported to the liver.
21. Digestion begins in the mouth, well before food reaches the stomach. When we see, smell, taste, or even imagine a tasty meal, our salivary glands in front of the ear, under the tongue, and near the lower jaw begin making saliva (spit).
22. 4
23. Cartilage
24. These signals are sent by the endocrine organs, which secrete chemicals—the hormone—into the extracellular fluid. Hormones are transported primarily via the bloodstream throughout the body, where they bind to receptors on target cells, inducing a characteristic response.
25. T cells do not recognize free-floating or cell-bound antigens as they appear on the surface of the pathogen. They only recognize antigen on the surface of specialized cells called antigen-presenting cells. Antigens are internalized by these cells.
26. Neurons are specialized cells that are capable of sending electrical as well as chemical signals. Most neurons contain dendrites, which receive these signals, and axons that send signals to other neurons or tissues. There are four main types of neurons: unipolar, bipolar, multipolar, and pseudounipolar neurons.
28. Antibodies. Antibodies help the body to fight microbes or the toxins (poisons) they produce. They do this by recognising substances called antigens on the surface of the microbe, or in the chemicals they produce, which mark the microbe or toxin as being foreign. The antibodies then mark these antigens for destruction.
29. A disease causative agent is substance that causes disease. Examples include biological pathogens (such as a virus, bacteria, parasites, and fungus), toxins, tobacco, radiation, and asbestos.
30. The third line of defense is specific resistance. This system relies on antigens, which are specific substances found in foreign microbes. Most antigens are proteins that serve as the stimulus to produce an immune response. The term "antigen" comes from ANTI-body GENerating substances.

What are three things that happened in Hawaiian economic history that encouraged the growth of the sugar industry?
Answers
In 1825, the first sugar cane was planted in Hawaii for the purpose of harvesting sugar in Manoa Valley on Oahu. Two years later, the plantation failed. Ladd and Company established the first profitable sugar cane plantation in Koloa, Kauai, in 1835.
What happened to the sugar industry in Hawaii?The sugar grown and processed in Hawaii was mostly sent to the United States and, in smaller quantities, to the rest of the world. The major employers in Hawaii were sugarcane and pineapple plantations. Both are now obsolete, with production shifting to other countries.
The Hawaiian Reciprocity Treaty with the United States was signed. This pact permitted Hawaiian sugar and other products to be sold duty-free in the United States. In exchange, the United States got land in the Puu Loa area, later known as the Pearl Harbor naval facility.
