Special Definitions Flashcards
Properties of a solution that depend strictly on the total number of dissolved solutes, and not the specific type of solute, are called:
Colligative properties
The measure of an atom’s ability to attract electrons when in a bond with another atom is called its:
Electronegativity
A sphere formed from the aggregation of long amphipathic molecules when they are mixed with water is called a:
Micelle
The heat energy required to raise the temperature of 1 gram of a substance by 1 degree Celsius is referred to as:
Specific Heat
cis/trans isomers
Organic molecules with the same chemical composition but existing in two different configurations determined by the positions of hydrogen atoms on the two carbons of a C═C double bond. When the hydrogen atoms are on the same side of the double bond, it is called a cis isomer; when on the opposite sides of the double bond, it is a trans isomer.
enantiomer
One of a pair of stereoisomers that exist as mirror images.
Steroids with a hydroxyl group are known as:
Sterols
Domain (not taxonomy)
A domain is a portion of a protein with a particular structure and function.
Autophagy
The body’s way of breaking down damaged cells, in order to regenerate newer, healthier cells.
Alleles
Variations of genes inherited in pairs from two parents
Dominant trait
A dominant allele exerts its phenotypic effect in a heterozygote and is written as a capital letter.
Recessive trait
A recessive allele only exerts its phenotype when not in the presence of the dominant allele and is written as a lowercase letter.
Phenotype
Phenotype is a characteristic of an organism that can be observed and measured.
Homozygous
An organism with two identical alleles for a genes.
Heterozygous
An organism with two different alleles for a gene.
