The _ is a metric unit of volume

Liter

For ease of understanding, scientists report measurements using the __ system

SI Unit

Whether applications of science to everyday life are considered good, bad, right, or wrong comes under the category of _

ethics

A brain scan is an example of __

technology

The theme that reflects the idea that there has been a gradual change in the characteristics of species over time is __

evolution

Living things adjust to a stimulus by a reaction called a

response

Living things change during lives through

growth and development

All living things __ to make more living things

reproduce

The study of standards for what is right and what is wrong is called

ethics

The information gathered from experiments is called

the data

A scientific explanation of known facts arrived at through repeated testing over time is a

theory

To use data to support a particular point of view

This is NOT a goal of science

Information gathered from observing a plant that grows 3 cm over a two-week period results in

data

using a feeling about what should occur

This is NOT a way scientists generate hypotheses

Scientific hypotheses must be proposed in a way that

enables them to be tested

The ability to reproduce results is an important port of any

experiment

The work of scientists begins with

careful observations

A controlled experiment allows the scientist to isolate and test

a single variable

Scientists publish the details of important experiments so that

their work can be repeated, their experimental procedures can be reviewed, and so that others can try to reproduce the results

The process by which organisms keep their internal conditions fairly constant is called

homeostasis

In the metric system, the basic unit of length is the

centimeter

the gradual change in the characteristics of a species over time

evolution

the living and nonliving factors in an organism's surroundings

environment

Any structure, behavior, or internal process that enables an organism to better survive in an environment

adaptation

An organism's tendency to maintain a stable internal environment

homeostasis

the series of changes that an organism undergoes during its lifetime

development

the process whereby an organism produces more of its own kind

reproduction

its flow through ecosystems determines how organisms interact and powers all life processes

energy

a variety of structural and behavioral adaptations help organisms relate their internal environment

homeostasis

organisms depend on internal and external systems that interact in complex ways to help them perform their life functions

systems and interactions

Over time, gradual changes in structures, behaviors, and internal processes of organisms result in diversity of species

evolution

although different organisms interact within ecosystems to form a stable system, all living things share the same characteristics of life

unity within diversity

biology is a continuous search for information about the natural world

nature of science
