characteristics of ALL life

• Living things are made up of organic molecules that contain nucleic acids, proteins, carbohydrates, and lipids.
• Living things are composed of cells.
• The smallest unit of matter that can't be broken down any further is the atom.
• Living things grow and reproduce.
• Living things use energy and raw materials.
• Living things respond to their environment.
• Living things maintain homeostasis.
• Populations of living things have adaptive traits and evolve.
• Atom is a unit of matter that cannot be further broken down.
• A molecule is the chemical components of cells.
• An organelle is a component within the cell that carries out specific functions.
• A cell is the smallest unit of life.
• A tissue is a group of similar cells that perform the same function.
• An organ is a structure with two or more tissues working together to perform a function.
• Organ systems are at least two organs working together to perform a function.
• All living things maintain homeostasis, which is a condition of equilibrium within any biological system.
• All living things grow and reproduce through sexual reproduction asexual reproduction
• Negative feedback is a change in a variable that triggers a control mechanism to counteract further change in the same direction.
• Catabolism is the breaking down of complex molecules into more simple ones.
• Anabolism is the assembly of simple molecules into more complex molecules.
• Populations of living things have adaptive traits and evolve.
• All living things respond to their environment by detecting stimuli and then reacting.
• Humans belong to the kingdom Animals - Domain Eukarya
• All living things use energy and raw materials by taking up and metabolizing compounds from their environment.
• Metabolism is the sum of all chemical reactions within living cells.
• Positive feedback is a change in a variable that triggers a control mechanism to amplify rather than reverse the change.
• An individual is a single organism.
• A population is all the individuals of the same species in an area.
• A community is all the species in an ecosystem that can interact.
• An ecosystem is a community and its physical environment.
• The biosphere is the part of the earth that supports life.
• sexual reproduction (sperm and egg )
• Asexual reproduction ( splitting of the cell )
• atom is a unit of matter that cannot be further broken down
• molecule is the chemical components of cells
• organelle is a component within the cell that carries out specific functions
• cell is the smallest unit of life
• Tissue is a group of similar cells that perform the same function
• an organ is a structure with two or more tissues working together to perform a function
• organ system means at least two organs working together to perform a function
