Biochemistry and Cells
The levels of organization in living things
What is organelle, cell, tissue, organ, organ system, organism?
The two body systems that work together to move oxygen throughout the body and deliver it to cells
What are the respiratory and circulatory systems?
These organic compounds are used to cut, copy and paste DNA
What are enzymes?
Term meaning the process by which organisms that are better adapted to their environment survive and reproduce is called this (aka "survival of the fittest")
What is natural selection?
Factors in an ecosystem that are non-living, such as temperature, sunlight, water, oxygen, carbon dioxide, pH of soil, etc. are called
What is abiotic?
These two structures are involved in the synthesis of cellular proteins
What are the nucleus and ribosomes?
The hormone secreted by the pancreas that regulates blood sugar level in humans is
What is insulin?
Traits are passed from parent to offspring. These traits are determined by
What are genes? (will also accept what is DNA?)
Term meaning differences found in living things, such as beaks in finches
What is variation?
Organisms that break down dead plants and animals and recycle nutrients are known as
What are decomposers?
This cellular structure is the site of cellular respiration, a process in which glucose is broken down in the presence of oxygen into energy (ATP) for the cell
What is the mitochondrion?
What is providing muscle cells with oxygen and removing carbon dioxide?
Compared to normal body cells, gametes contain this much genetic material
What is half?
Scientists can determine how closely related two individuals or species are using this laboratory technique in which DNA is separated into bands based on size
What is gel electrophoresis?
One negative impact of human interference of ecosystems is loss of this, a term meaning variety of life
What is biodiversity?
Antibodies, enzymes, and hormones have a specific function due to their specific
What is shape?
The guard cells of a plant open and close the stomata in the leaves to help maintain homeostasis by
What is preventing water loss and allowing for gas exchange (carbon dioxide in, oxygen out)?
This structure is responsible for the passage of materials (such as oxygen, carbon dioxide, and nutrients) between mother and fetus
What is the placenta?
Scientists can determine how closely two individuals or species are by comparing their amino acid sequences. Amino acids are the building blocks used to make these molecules
What are proteins?
The process in which an area is changed over time, or after an event such as a volcanic eruption or fire, is called this
What is ecological succession?
Movement of molecules from high to low concentration in which energy is not used
What is diffusion?
The substances found on the surface of pathogens that stimulate an immune response are known as
What are antigens?
The process in which different cells and tissues form during embryonic development is called this
What is differentiation?
Variation in living things is caused by what processes
What are mutation, meiosis and fertilization?
The maximum population an ecosystem can support is called this
What is carrying capacity?
