Science Final Review. Study Quiziz. Code 723586

Insoluble

incapable of being dissolved

recessive trait

A trait that needs both parents to have for offspring to get it.

roots

Absorbs water and minerals from the ground. Anchors plant in ground.

Lungs

Main organs of the respiratory system

Density

Mass per unit volume. The more dense, the more something sinks in water. The less dense, the more it floats.

Solubility

The ability to dissolve in another substance

food web

a system of interlocking and interdependent food chains.

Adaptation

A characteristic that improves an individual's ability to survive and reproduce in a particular environment. Born traits. Study evolution slide

Pedigree chart

A chart which shows several generations of related families and how traits are passed down through the offspring.

Symbiosis

A close relationship between two species that benefits at least one of the species.

Omnivore

A consumer that eats both plants and animals

infectious disease

A disease that is caused by a pathogen and that can be spread from one individual to another.

Mutualism

A relationship between two species in which both species benefit

Scientific Method

A series of steps followed to solve problems including collecting data, formulating a hypothesis, testing the hypothesis, and stating conclusions.

Respiratory system

A system of organs, functioning in the process of gas exchange between the body and the environment, consisting especially of the nose, nasal passages, nasopharynx, larynx, trachea, bronchi, and lungs. Study slideshow.

Kingdoms

Classifications of Living things.

Diaphram

Controls the amount of light passing through the opening of the stage

Transpiration

Evaporation of water from the leaves of a plant

endocrine system

Glands secrete hormones that regulate processes such as growth, reproduction, and nutrient use (metabolism) by body cells.

Animal cells

Have a cell membrane, not a cell wall. Animal cells can move. And has centrioles. Study slide

Homozygous

Having two identical alleles for a particular gene

classification system

Kingdom, Phylum, Class, Order, Family, Genus, Species

anerobic respiration

Respiration that does not require oxygen (2 ATP)

aerobic respiration

Respiration that requires oxygen. (36 ATP)

Digestive system

System that breaks down food and eliminates wasteful. Study slide

Evolution

The gradual change in a species over time. Study slide

Respiration

The process by which cells break down simple food molecules to release the energy they contain.

water cycle

The process of water evaporating and becoming perciputaion

Genetics

The scientific study of heredity. Study slide

Magnets

The source of the magnetic fields, usually an electromagnet.

circulatory system

Transports oxygen, waste, nutrients, hormones, heat, etc... around the body. Also re re-oxygenating blood. Study the slides

Mitosis

Unicellular cell division

Extinction

When an organism spieces dies out

conservation of matter

a fundamental principle of classical physics that matter cannot be created or destroyed in an isolated system

animal

a living organism that feeds on organic matter, typically having specialized sense organs and nervous system and able to respond rapidly to stimuli.

Budding

a new organism grows by mitosis and cell division on the body of its parent

fungus

a parasitic plant lacking chlorophyll and leaves and true stems and roots and reproducing by spores

ecological succession

a series of more-or-less predictable changes that occur in a community over time. Ex. Pond dries and turns to grassland. Then over time turns into a forest.

dominant trait

a trait that will appear in the offspring if one of the parents contributes it. Overrides récessive trait

Gene

a unit of heredity that is transferred from a parent to offspring and is held to determine some characteristic of the offspring.

Zygote

fertilized egg

life processes

functions that a living thing must carry out in order to stay alive. (Ex. metabolism, responsiveness, movement, growth, differentiation, reproduction)

Photosynthesis

process by which plants and some other organisms use light energy to convert water and carbon dioxide into oxygen and high-energy carbohydrates such as sugars and starches

asexual reproduction

process of reproduction involving a single parent that results in offspring that are genetically identical to the parent. There is budding and binary fission.

light source

projects light upwards through the diaphragm to allow you to see the specimen

Protists

single-celled or simple multicellular eukaryotic organisms that generally do not fit in any other kingdom

Phenotype

the set of observable characteristics of an individual resulting from the interaction of its genotype with the environment.

environment

the surroundings or conditions in which a person, animal, or plant lives or operates.

excretory system

the system that removes waste from your body and controls water balance. Study slide

Chromosomes

threadlike structures made of DNA molecules that contain the genes

measuring volume of a liquid

use a graduated cylinder. Measured in liter or mL.

Bacteria

(microbiology) single-celled or noncellular spherical or spiral or rod-shaped organisms lacking chlorophyll that reproduce by fission

Plant cells

1) have cell wall 2) have chlorophyll/chloroplasts 3) large central vacuole. Study slide

Energy

Allows living things to perform life processes.

Heterozygous

An organism that has two different alleles for a trait

Consumers

An organism that obtains energy and nutrients by feeding on other organisms or their remains.

Cells

The basic unit of structure and function in all living things

microsope

Fertilization and Development

sperm and egg make contributions to zygote sperm contributes DNA and a centriole(centriole becomes centrosome which organizes the spindle for mitosis) egg contributes DNA, organelles(mitochondria), nutrients, transcription factors, and mRNAs (known as cytoplasmic determinants)
