Biology Section 1-1 Review: The World Of Biology

The organization of a rock is much simpler than that of living things. By what other criteria can a rock be distinguished from living things?

By if it is living or nonliving, and also by it's looks.

Contrast the reproduction of bacteria with that of frogs.

Hereditary information recombines from two organisms of the same species.

Explain why the cell is called the basic unit of life.

It is the smallest unit that can preform all life's processes.

Why is it important to study biology?

It offers an organized and scientific framework for proposing and answering such questions about how living things work, interact, and change.

Reproduction

Process of producing offspring.

Tissue

A collection of specialized cells and cell products that preform a specific function.

Organ

A collection of tissues that carry out a specialized function of the body.

Give a specific example of homeostasis.

An owl's temperature is maintained at about 40 degrees C (104 degrees F)

Biology is the study of a. animals. b. plants and animals. c. all living things. d. energy transfer

C. all living things.

Explain how the drawing below illustrates the characteristics of life. (a big animal eating grass next to a little animal)

The big animal had the little animal, so he/she could grow big and have more animals when he/she is grown.

Development

The gene-directed process by which an organism matures.

Photosynthesis is part of a plant's a. metabolism b. homeostasis. c. development. d. response to stimuli..

a. metabolism.

A short segment of DNA that contains instructions for the development of a single trait of an organism is known as a. DNA loop. b. gene. c. library. d. membrane.

b. gene

Homeostasis refers to the a. organization of cellular structures. b. stable level of internal conditions in organisms. c. organized structure of crystals. d. destruction of tropical rain forests.

b. stable level of internal conditions in organisms.

As the cells in a multicellular organism multiply, they become specialized for different functions in a process called a. sexual reproduction. b. descent with modification. c. photosynthesis. d. cell differentiation.

d. cell differentiation.
