What is Cell Theory? - 1) All cells arise from preexisting cells. 2) Cells can carry out the processes of life. 3) Organisms are made of cells that function together. The end products of photosynthesis are? - Oxygen & Glucose The process of cytoplasm division during plant cell replication is known as? - Cytokinesis What principle is this? "An object immersed in a fluid is buoyed up by a force equal to the weight of the fluid displaced by the object." - Archimede's Principle Hardening of the arteries is known as? - Arteriosclerosis Cholesterol known as LDL means? - Low Density Lipoproteins What does Lock & Key model mean? - A model for enzyme actions what formula indicates the ideal as law? - PV=RnT Receiving a vaccine against a disease, what type of immunity is this considered? - Active. An alternate form of a gene is called? - allele What is an allele? - An allele is one of two or more forms of a gene or a genetic locus. If an organism has two sets, they are diploid. The study of the structure of organs and body systems is called? - Anatomy What is an atom with a negative charge? - anion (- ion) What is an atom with a positive charge? - cation (+ ion) what carries blood away from the heart? - arteries Arteries carry blood away from the heart to the? - Capillaries What are veins? - carries blood from the capillaries back to the heart (02 poor) What are arteries? - Carry oxygen rich blood away from the heart What are capillaries? - Capillaries are the exchange vessels. They are microscopic and have only one wall—tunica intima—allowing substances to pass through quickly. What is an atom? - An atom is the smallest unit of matter that still remains the properties of an element. what is an atomic mass number? - Equals the total number of protons and neutrons found within the nucleus of a atom. What is an atomic number? - the number of protons/electrons that an element has (ex. Carbon's number is 6: it has six protons; it has six electrons.) What is an autotroph? - An organism that makes its own food. What is are vacuoles? - "containers" or holding units in animal cells for water and organic substances. what are lysosomes? - -intracellular digestion What are peroxisome? - Contain oxidase enzymes that detoxify alcohol, hydrogen peroxide, and other harmful chemicals Adenine and guanine are purines that have? - 2 ring structure What is an axon? - Transmit impulses AWAY from cell body of neuron In an redox reaction the reducting agent will? - Lose electrons and be oxidized.
