EARTH AND LIFE SCIENCE

• Metamorphic rocks are formed from the transformation of existing rocks through heat and pressure.
• Ecology is the branch of biology that deals with the study of living organisms and their relationships with each other and their environment.
• Genes provide instructions that will direct cellular growth and development, ensuring that a species’ young will grow up to exhibit many of the same characteristics as its parents.
• All living things share fundamental properties that define a living organism.
• Unifying themes refer to common characteristics that all living things have and share.
• Unifying themes show the connections among living things and how they interact with each other and with their environment.
• A relationship exists between structure and function at all levels of biological organization.
• In biology, structure is always related to function.
• Within the many kinds of organisms in the living world, body structures seem carefully designed to carry out their functions.
• The theory of evolution helps explain how all the kinds of organisms came into existence.
• The theory of evolution helps explain why organisms look the way they do and how organisms of the past are related to organisms alive today.
• The theory of evolution explains the relationship among various groups of living organisms.
• Charles Darwin proposed the Theory of Evolution, which proposes organisms with more favorable traits will be more likely to survive and reproduce.
• These traits are called adaptation.
• An ecosystem consists of a community of organisms together with their physical environment.
• An ecosystem can be of different sizes and can be marine, aquatic, or terrestrial.
• Broad categories of terrestrial ecosystems are called biomes.
• Organisms need an ecosystem or physical environment to survive.
• Living things interact with each other and with the environment.
• A group of organs that work together form the different organ systems.
• Plants undergo photosynthesis where they convert the energy from the sun into sugar.
• All living organisms reproduce either through asexual or sexual reproduction.
• A group of tissues that perform the same functions form the organs.
• Some examples of animals that undergo asexual reproduction include earthworms, hydra, and planaria.
• All organisms grow and develop according to specific instructions coded for by their genes.
• Most animals cannot produce their own energy, they get the energy from the consumption and assimilation of the biomass of plants and other animals.
• In sexual reproduction, the offspring inherits the genes from two individual parents.
• Organisms act to keep their interior conditions relatively constant despite the varying environment.
• All living organisms are made up of cells.
• Cells come together to form tissues.
• In asexual reproduction, the offspring inherits the genes from a single parent.
• An organism consists of many organ systems but functions as one individual.
• Growth refers to an increase in size evident through physical change.
• Living organisms obtain energy from the food they eat.
• Homeostasis is the ability of an organism to regulate their internal conditions.
• Cells are considered as the basic unit of life.
• Development refers to a process of gradual transformation.
• Reproduction ensures the survival of species.
• The human body maintains an internal temperature of 37 ºC (98.5 ºF) regardless of the weather conditions.
• Theory of Special Creation was proposed by Spanish monk Father Sudrez according to which all the different forms of life that occur today on Earth have been created by God.
