Answer the following question given this paragraph: Paleontology, another branch of biology, uses fossils to study life's history (Figure 1.20). Zoology and botany are the study of animals and plants, respectively. Biologists can also specialize as biotechnologists, ecologists, or physiologists, to name just a few areas. This is just a small sample of the many fields that biologists can pursue. Biology is the culmination of the achievements of the natural sciences from their inception to today. Excitingly, it is the cradle of emerging sciences, such as the biology of brain activity, genetic engineering of custom organisms, and the biology of evolution that uses the laboratory tools of molecular biology to retrace the earliest stages of life on earth. A scan of news headlineswhether reporting on immunizations, a newly discovered species, sports doping, or a genetically-modified fooddemonstrates the way biology is active in and important to our everyday world. Q: What branch of biology uses fossils to study life's history? Choices: - morphology - entomology - gerontology - paleontology A:
paleontology
Answer the following question given this paragraph: Female monotremes lack a uterus and vagina. Instead, they have a cloaca with one opening, like the cloacas of reptiles and birds. The opening is used to excrete wastes as well as lay eggs. Q: Female monotremes lack a uterus and vagina. instead they have what? Choices: - endometrium - placenta - urethra - cloaca A:
cloaca
Q: Answer the following question given this paragraph: Populations gain individuals through births and immigration. They lose individuals through deaths and emigration. These factors together determine how fast a population grows. Q: What do populations gain through births and immigration? Choices: - humans - Over Population - Over Crowding - individuals A:
A: individuals
Question: Answer the following question given this paragraph: Solstice refers to the position of the Sun when it is closest to one of the poles. At equinox, the Sun is directly over the Equator. Q: When is the sun directly over the equator? Choices: - Winter - Midsummer - Fall - equinox A:
Answer: equinox

Answer the following question given this paragraph: Some single-celled organisms such as bacteria can group together and form a colony. A colony refers to a group of individual organisms of the same species that live closely together. This is usually done to benefit the group, such as by providing a stronger defense or the ability to attack bigger prey. A colony can also form from organisms other than bacteria. A bacterial colony often defends from a single organism, producing a colony of genetically identical individuals. Q: What refers to a group of individual organisms of the same species that live closely together? Choices: - a enviroment - a flock - a habitat - a colony A:
**Answer**
a colony

Answer the following question given this paragraph: Mammals generate heat mainly by keeping their metabolic rate high. The cells of mammals have many more mitochondria than the cells of other animals. The extra mitochondria generate enough energy to keep the rate of metabolism high. Mammals can also generate little bursts of heat by shivering. Shivering occurs when many muscles contract a little bit all at once. Each muscle that contracts produces a small amount of heat. Q: Mammals generate heat primarily by maintaining a high rate of what? Choices: - reproduction - respiration - movement - metabolism A:
(Answer)
metabolism
