Which of the following statements is true for all eukarya?

their cell do not contain a nucleus and they have a similar cell wall when compared to bacteria.

their cells do not contain a nucleus.

their cells do not contain a nucleus and they have a different cell wall from bacteria.

Perhaps the single greatest contribution Linnaeus made to science was his development of the process called binomial nomenclature. Which of the following descriptions below most accurately describes this process?

gives each species a unique, two-word Latin name

provides a list of 4 kingdoms to which each species is placed into

classifies organisms based on their cellular organelle characteristics, such as the presence or absence of a nucleus

organizes each individual organisms down to their species name

Classification (SC.6.L.15.1)

Enzyme Classifications Traditionally, enzymes were simply assigned names by the investigator who discovered the enzyme. As knowledge expanded, systems of enzyme classification became more comprehensive and complex. Currently enzymes are grouped into six functional classes by the International Union of Biochemists (I.U.B.). Number Classification Biochemical Properties 1 Oxidoreductases Act on many chemical groupings to add or remove hydrogen atoms. 2 Transferases Transfer functional groups between donor and acceptor molecules. Kinases are specialized transferases that regulate metabolism by transferring phosphate from ATP to other molecules. 3 Hydrolases Add water across a bond, hydrolyzing it. 4 Lyases Add water, ammonia or carbon dioxide across double bonds, or remove these elements to produce double bonds. 5 Isomerases Carry out many kinds of isomerization: L to D isomerizations, mutase reactions (shifts of chemical groups) and others. 6 Ligases Catalyze reactions in which two chemical groups are joined (or ligated) with the use of energy from ATP.
