Biology Chapter 4

What is an experimental group? – it's identical to the control group, except for one factor
hypotonic solution – water moves into the cell, cell bursts (lyses)
What are proteins? – *They transmit signals inside the cell.
*They act as a support structure.
*The provide pathways for substances to enter and leave the cell.
acetylcholine – Common vertebrate neurotransmitter, especially in neuromuscular junctions.
solute – A substance that is dissolved in a solution.
Left ventricle – receives blood from the left atrium and pumps it to the aorta
biennial plant – A plant that sprouts and grows in one season, then flowers, produces seeds, and dies the next season.
hypothalamus – The master control center of the system, located in the ventral portion of the vertebrate forebrain. The hypothalamus functions in maintaining homeostasis, especially in coordinating the endocrine and nervous systems; secretes hormones of the posterior pituitary and releasing hormones that regulate the anterior pituitary.
nucleic acid – (biochemistry) any of various macromolecules composed of nucleotid chains that are vital constituents of all living cells
The term that means inflammation of a tendon is
Neutron – A particle inside an atom with no charge.
superior vena cava – A large vein that returns O2-poor blood to the heart from the upper body and head.
Smooth Endoplasmic Reticulum – A network of membranes inside eukarytoic cells involved in lipid synthesis and storage
catalyst – A substance that enables a chemical reaction to proceed at a usually faster rate or under different conditions
(e.g., lower temperature)than otherwise possible without being changed by the reaction.
temperature, enzyme and substrate concentration – When running an experiment to test the effect of pH on enzyme activity, which factors would you need to control?
The term thаt meаns inflаmmatiоn оf a tendоn is
catalyst – A chemical agent that increases the rate of a reaction without being consumed by the reaction.
Homologous, Analogous – The anatomical evidence of evolution is divided in:
Amino Group – (—NH2) a functional group composed of nitrogen atom bonded to two hydrogen atoms and to the carbon skeleton. Can act as a base in solution, accepting a hydrogen ion and acquiring a charge of +1.
organism – An individual living thing, such as a bacterium, fungus, protist, plant, or animal.
Substrate – Reactant of an enzyme-catalyzed reaction
