Biology Chapter 18: The Evolution Of Invertebrate Diversity

Species – A group of organisms that are closely related and can mate to product fertile offspring; also the level of classifications below genius and above subspecies
Substrate – A specific reactant acted upon by an enzyme
Bacteria with weird or no cell wall – Won't stain with the Gram stain at all
Amino acid – The monomer in a protein is a(n) _____ ____.
Tissue – a group of similar cells from the same origin working together to perform a function
sebaceous gland – Produces an oily substance called sebum, that is used to lubricate the skin. They are usually attached to hair follicles.
passive immunity – Immunity conferred by transferring antibodies from an individual who is immune to a pathogen to another individual.
Name four types of macromolecules. – nucleic acids, lipids, proteins, carbohydrates
Cytoskeleton – Network of protein filaments called microfilaments and microtublules
osmotic pressure – Force produced by the pressure of water diffusing through a semipermeable membrane; the greater the difference in water concentration on either side of the membrane, the greater the osmotic pressure
A young woman is found comatose, having taken a certain number of sleeping pills an unknown time before.  An arterial blood sample yields the following values. The normal values are given in parentheses.             pH:             6.90 (7.35-7.45)             HCO3- :      40 mEq/liter (22-28 mEq/L)             PaCO2  :     68 mmHg (38-42 mmHg)        This patient’s acid-base is most accurately described as:
Enantiostasis and Plants – Halophytes are plants adapted to salty environments due to being either; Salt excluders such as the Grey Mangrove, discard salt via the roots, Salt excreters have glands in the leaves to give off salt such as the River Mangrove and Salt Accumulators like the Milky Mangrove, leaves store salt.
Polysaccharide – Carbohydrates that are made up of more than two monosaccharides
Speciation – Formation of two or more species from an original ancestral species.
mechanical isolation – Morphological differences prevent fertilization.
A yоung wоmаn is fоund comаtose, hаving taken a certain number of sleeping pills an unknown time before.  An arterial blood sample yields the following values. The normal values are given in parentheses.             pH:             6.90 (7.35-7.45)             HCO3- :      40 mEq/liter (22-28 mEq/L)             PaCO2  :     68 mmHg (38-42 mmHg)        This patient’s acid-base is most accurately described as:
DNA – Double stranded helix that contains the genetic code
feedback inhibition – A method of metabolism control in which a product of a metabolic pathway acts as an inhibitor of an enzyme within that pathway.
volvox – a unicellular protist that has chloroplasts and can carry out photosynthesis. It lives and travels in colonies (or groups). One colony or group can contain 500 to 60,000. It moves by using flagella.
