The structural and functional unit of every living being.
What is a cell?
Made of atoms that are bonded together, they can be composed the same elements or different.
What are molecules?
It is formed by several organ systems or apparatuses. A person is an example of this.
What is an organism? What is an individual?
The smallest units of an element that retain the element’s physical and chemical properties.
What are atoms?
The layer of the Earth where life is present. It includes the oceans and bodies of water, the earth surface and the lower part of the atmosphere.
What is the Biosphere?
Living things need energy to carry out all of their functions. To achieve this, they carry out a series of chemical reactions that transform matter into energy or structural material necessary for the cell or viceversa.
What is metabolism?
Living things need to maintain a constant internal environment or balance despite changes in the environment and the tendency towards disorganization.
What is homeostasis?
Organisms perceive and react to stimuli in the environment, and generate responses.
What is irritability?
Living things adapt to changes in their environment and transmit this ability to their offspring through generations.
What is evolution?
The cell is composed of individual parts that work together as a unit. Cells of the same type can come together to form tissues; a group of tissues that carry out a specific function is an organ; organs can come together to form organ systems, etc.
What is order?
A group of cells that work towards the same function.
What are Tissues?
The grouping of living factors and abiotic factors together.
A group or addition of tissues that perform a function in common.
What is an organ?
Formed by biomolecules. Those are the molecules that compose biological matter. These are found within cells.
What are organelles?
A group of organisms of the same species within a determined area.
What is a population?
Provide the definition of a cell
The structural and functional unit of every living being. Some organisms are unicellular and don’t form tissues, organs or organ systems
What is a community?
A group of populations that interact with each other.
The ability to metabolize or convert external material into energy and use it to generate structures to increase size.
Light, pressure, temperature, or the composition of land, air or water composition are examples of?
Stimuli
Provide the definition of homeostasis
Living things need to maintain a constant internal environment or balance despite changes in the environment and the tendency towards disorganization.
If we put together:
What do we get?
A system. The respiratory system.
Evolution
Smallest units of an element that retain the element’s physical and chemical properties. These bond together to form molecules
Provide the definition of an ecosystem.
The grouping of living factors and abiotic factors together.
This can vary.
