Dive Biology Terms Lesson 7

Transformation – The uptake of random DNA by bacteria, who then express it as their own.
Codominant alleles – Pairs of alleles that both affect the phenotype when present in a heterozygote.
centrioles – consist of two short cylinders of microtubules at right angles to each other and are situated in the cytoplasm near the nuclear envelope
A polymer is what? – lots of monomers put together
isotonic – Solution that has an EQUAL concentration of dissolved particles compared with another solution
Structure – A protein's _________ determines its function.
What is metabolism? – the sum of all chemical reactions within an organism
vital capacity – The total amount of air that a person can forcefully exchange with the environment, which is the sum of the inspiratory volume, tidal volume, and expiratory reserve volume.
maturation region – in the _____________ _________ cells become fully differentiated and often, root hairs are produced. (also called the "zone of differentiation")
Which cell is responsible for myelin production in the PNS?
coniferous – term used to refer to trees that produce seed bearing cones and have thin leaves shaped like needles
What is evolution? – The continual change of a species over many generations, which results in new species, adapted to their environment.
Which cell is respоnsible fоr myelin prоduction in the PNS?
substrate – A specific reactant acted upon by an enzyme
Triglyceride – A glyceride occurring naturally in animal and vegetable tissues. It is composed of three chains of fatty acids bound together with a glycerol molecule using ester bonds.
day-neutral plant – A plant whose flowering is not affected by photoperiod.
Cilium – A short, hairlike projection from the surface of certain eukaryotic cells that contains microtubules in a 9 + 2 arrangement. The movement of cilia may propel cells through a fluid medium or move fluids over a stationary surface layer of cells.
