BACTERIA

A member of a large group of unicellular microorganisms that have cell walls but lack organelles and an organized nucleus, including some that can cause disease

there is a small amount of bacteria growing on this old cheese

COMPLETE DOMINANCE

A kind of dominance wherein the dominant allele completely masks the effect of the recessive allele in heterozygous condition

 Brown eyes is an example of complete dominance

VESTIGIAL ORGAN

body structures considered to have been better developed and functional in the past but to have now lost most or all of their function and some or most of their structure

the male nipple is an example of a vestigial organ

BUFFER

A solution that resists changes in pH when acid or alkali is added to it; typically involve a weak acid or alkali together with one of its salts

 Blood is an example of a buffer (it is hard to see, but it's there)

TRAIT

A genetically determined characteristic

 I (right) inherited the curly hair from my mother (left)

ADHESION

When particles of different substances stick together

The water vapor particles are sticking to the mirror

COHESION

When particles of the same substance stick together

the particles of the putty are sticking together

CARNIVORES

An animal that feeds on flesh

a betta fish is a carnivore but it mostly eats betta pellets, which is made from fresh seafood

HERBIVORES

An animal that feeds on plants

llamas are herbivores

OMNIVORES

An animal or person that eats food of both plant and animal origin

a human such as this boy, can eat plants (vegetables, fruits, ect..) and meat

EPITHELIAL TISSUE

Cells which form a lining on the outside of the body and on the inside of the respiratory and digestive tracts and other organs

skin is made up of epithelial tissue

SIMPLE FRUIT

An indehiscent fruit derived from a single ovary having one or many seeds within a fleshy wall or pericarp

an apple is a simple fruit

TOPSOIL

The top layer of soil

INVERTEBRATES

An animal lacking a backbone

an ant is an invertebrate

HETEROTROPH

An organism deriving its nutritional requirements from complex organic substances

a dog does not make its own food, it is derived from other things

AUTOTROPH

An organism that is able to form nutritional organic substances from simple inorganic substances

plants make their own food using the process of photosynthesis

PHOTOSYNTHESIS

The process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water; (in plants) generally involves the green pigment chlorophyll and generates oxygen as a byproduct

this plant uses the process of photosynthesis to create its own food and keep the pigment green

OSMOSIS

A process by which molecules of a solvent tend to pass through a semipermeable membrane from a less concentrated solution into a more concentrated one, thus equalizing the concentrations on each side of the membrane
               before osmosisafter osmosis

BASE

A substance capable of reacting with an acid to form a salt and water, or (more broadly) of accepting or neutralizing hydrogen ions; has a pH between 8 and 14

 Nail Polish remover is a basic substance

EVAPORATIVE COOLING

Reduction in temperature because of the evaporation of a liquid, which removes latent heat from the surface from which evaporation takes place; process is employed in industrial and domestic cooling systems

CARBON

A Group 14 element; distributed very widely in nature; widely distributed throughout the sun, stars, and atmospheres of most planets; found free in nature in three allotropic forms: amorphous, graphite, and diamond
