____________ is best described as away of knowing. Science

A well-tested explanation that explains a lot of observations is a theory

A personal preference or point of view is a bias

The process by which organisms keep everything inside their bodies within certain limits is called homeostasis.

The branch of biology dealing with interactions among organisms and between organisms and their environment is called ecology

The simplest grouping of more than one kind of organism in the biosphere is a community

The lowest level of environmental complexity that includes living and nonliving factors is the ecosystem

Give an example of a primary producers plants

__________ get their energy by consuming only plants. herbivores

__________ get their energy by consuming only other animals. carnivores

What animals eat both producers and consumers? omnivores

A word that means the same thing as consumer is heterotroph

The repeated movement of water between Earth’s surface and the atmosphere is called the water cycle

Nonliving factors in the environment abiotic

Living factors within an ecosystem biotic

Which are two ways a population can increase in size? increased in birthrate and immigration

Something that controls the growth or size of a population is a limiting factor

Competition, predator/prey relationships, parasitism, crowding, and disease are examples of density- ____________ limiting factors dependent

Which are two ways a population can decrease in size? decreased birthrate and emigration

The gray-brown haze often found over large cities is called smog

Who used a compound microscope to see chambers within cork and named them “cells”? Robert Hooke

What advance in technology made the discovery of cells possible? the microscope

Cells are the basic units of life. All living things are made of cells. All cells are produced from existing cells. The following are principle of the__________ cell theory

Looking at a cell under a microscope, you note that the cell lacks a nucleus. What kind of cell is it? prokaryote.

Give an example of a prokaryotes? bacteria

Which organelle converts the chemical energy stored in food into compounds that are more convenient for the cell to use? mitochondrion

Storing DNA is a function of the nucleus

Which organelle would you expect to find in plant cells but not animal cells? chloroplast

Which of the following structures serves as the cell’s boundary from its environment? cell membrane

Which means of particle transport requires input of energy from the cell? active transport

An ______________is a group of organs that work together to perform a specific function. organ system

A group of similar cells that perform a particular function is called a tissue.

__________ is released from ATP when a phosphate group is removed. Energy

Organisms that cannot make their own food and must obtain energy from external sources are called heterotrophs

Autotrophs produce carbohydrates during photosynthesis

In the overall equation for photosynthesis, six molecules of carbon dioxide and six molecules of water result in a molecule of sugar and six molecules of oxygen.

The products of the light- dependent reactions are ATP, NADPH, and __________. oxygen gas

Another name for the light-independent reactions is Calvin cycle

The Calvin cycle takes place in the stroma

What is a product of the Calvin cycle? high-energy sugars

What is the correct sequence of events in cellular respiration? glycolysis  Krebs cycle  electron transport

What are the reactants in the equation for cellular respiration? glucose and oxygen

What is the products of cellular respiration? Water, Carbon dioxide, and ATP

Cellular respiration is called an aerobic process because it requires oxygen

Where does glycolysis takes place in the cell? cytoplasm
