question

Data Collection

answer

This is the act of writing down the required information you get from a laboratory experiment.

question

Decomposer

answer

This is an organism that breaks down and gains nutrients from dead organisms.

question

Deforestation

answer

This is the removal of trees and the conversion of forest lands to farmlands, logged areas, or cities.

question

Density Dependent Limiting Factor

answer

This is a limiting factor of a population in which large, dense populations are more strongly affected than small, less crowded ones.

question

Density Independent Limiting Factor

answer

This is a limiting factor of a population that does not depend on the population density. These factors are usually abiotic factors.

question

Detritivore

answer

This is a heterotrophic organism that consumes dead or decayed tissue and helps to recycle nutrients in an ecosystem.

question

Diploid

answer

This is an organism or cell with two sets of chromosomes.

question

Diversity

answer

This is introducing a new or different quality to a group.

question

DNA

answer

This holds an organisms hereditary information.

question

Dominant

answer

This is an observable trait of an organism that can mask the recessive trait.

question

Earthquake

answer

This is a geologic event that occurs when tectonic plates are displaced violently.

question

Ecosystem

answer

Populations and abiotic factors with which they interact in the setting of a community.

question

Energy

answer

The capacity for doing work. It may be transformed from one form to another.

question

Energy Pyramid

answer

This display graphically shows the energy that is available at each trophic level in a a food chain.

question

Environment

answer

The conditions that surround someone or something. These conditions and influences affect the growth, health, progress, etc., of someone or something.

question

Erosion

answer

This is the movement of soil, mud and rock due to the downward movement of wind, water or ice.

question

Evidence

answer

This is data from an experiment, which is used to verify or reject the original hypothesis in the conclusion.

question

Evolution

answer

This is a change in the genetic makeup of a population or species over time.

question

Exponential Growth

answer

This is the type of growth experienced by a population that increases at a rate proportional to its size. The larger the population gets, the faster it grows.

question

Extinction

answer

This is the ceasing of the existence of any particular species.

question

Fertilization

answer

The process of one gamete (sex cell) joining another.

question

Field Investigation

answer

This is a scientific inquiry or process which is not conducted in a lab but in some setting from everyday life.

question

Food Chain

answer

This is a path for the transfer of matter and energy through an ecosystem by eating and being eaten.

question

Food Pyramid

answer

This is a graphical representation to show the biomass or energy available at each trophic level in a ecosystem.

question

Food Web

answer

A representation of the linkages between food chains in a community.

question

Fossil

answer

This is the mineralized remains of plants or animals.

question

Fossil Fuels

answer

Hydrocarbon-containing natural resources burned for energy.

question

Fossil Record

answer

This is the chronicle of evolution over millions of years of geologic time engraved in the order which fossils appear in rock strata.

question

Gamete

answer

This is a haploid cell with half the reproductive information from the parent.

question

Gene

answer

This is a segment of DNA on the chromosome that is coded for a particular trait.

question

Gene Pool

answer

This is the total number of genes of every individual in an interbreeding population.

question

Gene Splicing

answer

The cutting of DNA by specific enzymes known as restriction endonucleases. The cut piece from one organism is added to the DNA of another.

question

Genetic Variation

answer

This is one result of gamete formation through meiosis and fertilization during sexual reproduction that promotes biodiversity within a species.

question

Genetics

answer

This is the science of genes, heredity and variation of organisms.

question

Geographic Isolation

answer

This can occur when part of a population of a species becomes separated from the remainder, they may over time evolve different characteristics from the parent population.

question

Global Warming

answer

A theory of overall increase in world near-surface air and ocean temperatures which may be caused by additional heat being trapped by greenhouse gases. The increase of temperatures would cause significant changes in rainfall patterns, a rise in sea level, and a wide range of impacts on plants, wildlife, and humans.

question

Greenhouse Effect

answer

This is a warming of the planet due to carbon dioxide and heat retention.

question

Habitat

answer

The area where an organism lives its life including the living and nonliving factors.

question

Habitat Loss

answer

This is the process in which a natural habitat becomes unable to support the species present. Generally this results in a reduction in biodiversity.

question

Haploid

answer

This is a cell or organism having half of the diploid chromosome number, symbolized by "n".

question

Heat Energy

answer

This is the form of energy that is transferred because of a difference in temperature.

question

Heterotroph

answer

This is an organism that relies on complex organic substances for nutrition.

question

Homologous Structures

answer

These are physical features shared by organisms with common ancestry; they may have the same structure, but different functions developmentally mature organisms.

question

Data Collection

answer

This is the act of writing down the required information you get from a laboratory experiment.
