Biology
What role do mitochondria play in cells?
Mitochondria are the sites of aerobic respiration in cells, where energy is released from glucose to produce ATP.
What is the basic unit of life?
The cell
What is the process by which plants make their own food using sunlight?
Photosynthesis
Oxygen + Glucose -> Carbon Dioxide + Water + ATP
What is the process by which cells use oxygen to produce energy?
Cellular respiration
an organism that breaks down dead plants and animals and their waste products, returning vital nutrients to the ecosystem
Decomposer
Which system in the human body is responsible for defending against disease and infection?
Immune system
Another word for "synthesize"
Create
What term describes the process of an organism's physical characteristics changing over time to adapt to its environment?
Evolution
What process converts carbon dioxide into oxygen?
Photosynthesis
What molecule carries genetic information in all living organisms?
DNA (Deoxyribonucleic Acid)
a process where organisms better adapted to their environment tend to survive and reproduce more successfully
Natural Selection
An example of an autotroph.
Biuret test for protein
The reagent starts off a blue colour and turns violet/purple in the presence of protein
What is the function of enzymes, in general, in the body?
To reduce the energy required to start a chemical reaction.
What is the name of the process that produces gametes (sperm and egg cells) in animals?
Meiosis
Which gas do plants absorb from the atmosphere during photosynthesis and how does it enter plant cells?
Carbon dioxide (CO2)
Enters the leaf through stomata when the guard cells are turgid.
Dissolves on the damp outer surface of spongy mesophyl cells/palisade cells. Enters the cell
a heritable trait that enhances an organism's survival and reproduction in its environment
Adaptation
What is the term for the process by which a single cell divides to form two identical cells?
Mitosis
Which part of the cell stores DNA?
Nucleus
Which type of RNA is involved in protein synthesis?
mRNA
write the balanced symbol equation for photosynthesis
(light and chlorophyll - can't add these in the correct place but they need to be above the arrow)
6CO2 + 6H2O → C6H12O6 + 6O2
a random permanent change in the DNA sequence of an organism.
Mutation
What is the molecule that carries energy within cells?
ATP (Adenosine Triphosphate)
what organelle in a cell is the site of cellular respiration?
Mitochondria
the maximum population size of a species that a particular environment can sustainably support, given the available resources like food, water, and habitat
Carrying Capacity
