Part 1: General Science Flashcards
On a Fahrenheit thermometer the boiling point of water at sea level is (A) 100 degrees (B) 180 degrees (C) 212 degrees (D) 373 degrees
C
On a Fahrenheit thermometer the boiling point of water at sea level is 212 degrees. 100 degrees is the Celsius boiling point, and 373 degrees is the Kelvin boiling point.
\_\_\_\_\_ are necessary for the body's maintenance, growth, and repair. (A) Proteins (B) Carbohydrates (C) Fats (D) Vitamins
A
Proteins are necessary for the body’s maintenance, growth, and repair.
The process by which blood cells absorb oxygen ad eliminate carbon dioxide and water vapor is called (A) decomposition (B) photosynthesis (C) oxidation (D) respiration
D
The process by which animals convert oxygen and sugars into carbon dioxide and water is called respiration. The reverse process, by which plants convert carbon dioxide and water into sugar and oxygen, is called photosynthesis.
\_\_\_\_\_ carry blood back to the heart from the capillaries. (A) Arteries (B) Veins (C) Ventricles (D) Red blood cells
B
Veins carry blood back to the heart from the capillaries.
Which of the following depicts a chemical process? (A) Helium is combined with neon. (B) Iron forms rust. (C) Water causes soil erosion. (D) Ice melts
B
Iron forms rust when water turns iron and oxygen into iron oxide; this is a chemical process.
What blood type is a universal donor? (A) O (B) A (C) AB (D) B
A
Type O is the universal donor, which means that type O blood can be given to anybody.
Blood enters the right atrium of the heart from the (A) aorta (B) left ventricle (C) pulmonary vein (D) vena cava
D
Blood enters the right atrium of the heart from the vena cava.
Which of the following substances has the highest pH? (A) ammonia (B) battery acid (C) isopropyl alcohol (D) water
A
For a substance to have a high pH, it should be a base, or alkaline. A pH of 7 is neutral, like water; a pH of less than 7 is acidic; and a pH of greater than 7 is a base. Of the substances listed, only ammonia is a base.
The bulk of digestion takes place in the (A) pancreas (B) stomach (C) small intestine (D) large intestine
C
The bulk of digestion takes place in the small intestine. Food is broken down completely by enzymes produced in the walls of the small intestine, in the pancreas, and in the liver.
Which of the following is NOT part of the female reproductive system? (A) oviduct (B) uterus (C) ovary (D) testes
D
During human reproduction the male organ, or penis, ejaculates more than 250 million sperm, which is produced in the testes. In the female reproductive system, during ovulation, an egg, or ovum, is released from the ovary and begins to travel through the oviduct (Fallopian tube) and into the uterus.
A \_\_\_\_\_ is a unit of inheritance. (A) phenotype (B) genotype (C) allele (D) gene
D
A gene is defined as a unit of inheritance.
Which of the following is a sedimentary rock? (A) granite (B) marble (C) shale (D) slate
C
Shale, which derives from clay sediments, is an example of a sedimentary rock.
This is the collection of all populations of a habitat. (A) community (B) population (C) ecosystem (D) biome
A
A community is the collection of all populations of a habitat.
A vulture would be considered a (A) producer (B) decomposer (C) scavenger (D) consumer
C
A vulture is considered a scavenger. Also known as detritivores, these animals consume refuse and decaying organic matter, especially carrion, which is decaying flesh.
What type of rock is obsidian? (A) sedimentary (B) igneous (C) metamorphic (D) none of the above
B
Obsidian is a type of igneous rock.
