試題內容：
一、是非題(每題2分，計40分；對於以下各敘述，正確的請打O，錯誤的請打X)
1. Gravity has a significant effect on blood pressure, so fainting is helpful
by quickly increasing blood flow to one's brain when the blood pressure is
too low to provide adequate blood flow.
2. The filtrate in Bowman’s capsule is a mixture that contains salts,
glucose, amino acids, vitamins, nitrogenous wastes and mirrors the
concentrations of these substances in blood plasma.
3. When phospholipids are added to water, they self-assemble into bilayers
that shield their hydrophobic portions from water.
4. Trans fats may contribute more than cis and saturated fats to
atherosclerosis.
5. Uncontaminated rain has a pH of about 5.6, slightly acidic, owing to the
formation of carbonic acid from carbon dioxide and water.
6. Amino acids are organic molecules possessing both carbonyl and amino
groups.
7. Birds and mammals are mainly endothermic, meaning that they are warmed
mostly by heat from external sources.
8. In innate immunity, recognition and response rely on specific traits of
pathogens using a vast array of receptors.
9. The movement of oxygen and carbon dioxide across moist respiratory
surfaces takes place by either diffusion or active transport depending on
animal species and their habitats.
10. All the antigen receptors on a particular B cell are identical and bind
identical antigens, but those on a particular T cell are different and bind
different antigens.
11. Kangaroo rats, which live in desert, gain water mainly from cellular
metabolism and loses the largest fraction of it in urine.
12. Sickle-cell disease is caused by the substitution of one polar amino acid
for the normal nonpolar one at a particular position in the primary structure
of hemoglobin.
13. When blood osmolarity raises, more angiostensinis is released into the
bloodstream, and it will act on the collecting duct of the kidney to promote
increased reabsorption of water.
14. The lymphocyte diversity is generated by gene rearrangement after
encounter with pathogens.
15. Excesses of vitamin B complex are deposited in body fat, so
overconsumption may result in accumulating toxic levels of these compounds.
16. The molecular logic of life is simple but elegant: Small molecules common
to all organisms are ordered into unique macromolecules.
17. Water is one of the few substances that are less dense as a solid than as
a liquid.
18. Humans is most developed countries have an unusually low average daily
metabolic rate or about 1.5 times BMR ─ an indication of their relatively
sedentary lifestyles.
19. Animal form and function are correlated at all levels of organization.
20. The epithelial tissue functions as a barrier against mechanical injury,
pathogens, and fluid loss and also an active interface with the environment.
二、填充題(40分)：每格兩分：術語請以英文作答，而以正確中文術語作答者，每格1分
。
1. Biologists use two main types of scientific inquiry: (1) science and (2)
science.
2. Limitations of science are set by its requirements that hypotheses be
testable and (3) and that observations and experimental results be (4).
3. A drop in pH shifts the hemoglobin dissociation curve toward the (5), and
the curve of a fetus is located on the (6) of its mother’s.
4. An animal’s diet must supply (7), (8), and essential nutrients.
5. Many blood proteins, especially (9), create the osmotic pressure of blood.
The most abundant phagocytic cells in the mammalian body are (10), one type
of white blood cells.
6. Organisms build strong materials from structural polysaccharides. For
examples, (11) is a major component of the tough plant cell wall and (12) is
used by arthropods to build their exoskeletons.
7. Every cell of a multicellular animal must be bathed in (13). Exchange
between the (13) and (14) enables cells throughout the body to obtain
nutrients and get rid of wastes.
8. The (15) immune response defends against extracellular pathogens, in
contrast, the (16) immune response defends against extracellular pathogens
and cancer.
9. The roles of antibodies in immunity are (17), (18), and activation of
complement system and pore formation.
10. Osmoregulation is a general process by which animals control (19) and
balance (20) gain and loss.
三、問答題(20分)
1. 何謂反流交換機制(countercurrent exchange mechanism)？請舉一例說明之。
