Body System
The organ that is responsible for pumping blood throughout the body.
What is heart?
It is the basic unit of heredity.
What is a gene?
This green pigment in plants absorbs light energy, mainly from the red and blue wavelengths, to power photosynthesis.
What is chlorophyll?
This organelle is often called the “powerhouse of the cell” because it is the main site of cellular respiration.
What is the mitochondrion?
This term refers to the variety of life on Earth, including genetic diversity, species diversity, and ecosystem diversity.
What is biodiversity?
The part of the respiratory system is the site of gas exchange.
What is alveoli?
What do we call traits that are controlled by genes located on the X chromosome?
What are X-Linked Traits?
This gas enters the leaves through the stomata and is the main source of carbon atoms for glucose production in photosynthesis.
What is carbon dioxide (CO₂)?
This first stage of cellular respiration breaks down glucose into pyruvate and occurs in the cytoplasm.
What is glycolysis
This term refers to the number of individuals living in a given area or volume.
What is population density?
The component of blood that carries oxygen to the body’s cells.
What is red blood cell?
These are the building blocks of DNA, made up of a sugar, a phosphate group, and a nitrogenous base.
What are nucleotides?
The light-dependent reactions of photosynthesis take place in these sac-like structures inside the chloroplast.
What are thylakoids?
In the presence of oxygen, pyruvate enters this cycle, also known as the citric acid cycle, to produce NADH and FADH₂.
What is the Krebs cycle?
The number of organisms of one species that an environment can support
What is carrying capacity?
Which specific blood vessels supply oxygen and nutrients directly to the heart muscle?
What are coronary arteries?
This form of hypertrichosis, characterized by excessive hair growth on the external ear, is inherited as a Y-linked trait and passed only from father to son.
What is hypertrichosis pinnae?
This molecule, also known as the energy currency of the cell, is produced during the light-dependent reactions and used in the Calvin cycle.
What is ATP?
This stage of cellular respiration produces the most ATP, as electrons are passed along a chain of proteins and finally accepted by oxygen to form water.
What is the electron transport chain (ETC)?
hese environmental conditions, such as food, water, space, and shelter, restrict the growth, size, or distribution of a population.
What are limiting factors?
How does oxygen from the lungs enter the bloodstream?
What is diffusion?
These nitrogenous bases, cytosine, thymine, and uracil, are all classified as this type of base. They are characterized by having a single-ring structure.
What are pyrimidines?
This cycle, also called the dark reactions or light-independent reactions, uses ATP and NADPH to fix carbon dioxide into glucose.
What is the Calvin cycle?
The complete aerobic breakdown of one molecule of glucose can yield up to this many ATP molecules.
What is 36–38 ATP?
This process occurs when toxic substances, such as pesticides or heavy metals, increase in concentration as they move up the food chain.
What is biological magnification?
