How do prokaryotic cells divide?

10.2 – A prokaryotic cell first replicates its genetic information before cell division begins. In most prokaryotes, the rest of the process of cell division is a simple matter of separating the contents of the cell into two parts.

The properties of enzymes – Catalyst, protein, not used up in a reaction, specific, acts to lower the activation energy of a reaction, bonds with a substrate molecule at the enzyme's active site
Growth factors – What stimulates cell growth by promoting protein synthesis?
sclera – A layer of connective tissue forming the outer surface of the vertebrate eye. The cornea is the frontal part of the sclera.
speciation – Formation of a new species
Concentration – A measurment of how much solute exists within a certain volume of solvent
Mendelian Genetic Principle #2 – Each organism has two alleles that make up the genotype for a given trait
How can one species evolve into two species? – Geographical isolation may prevent two groups of the same species from mating. These two groups evolve differently and eventually become different species.
ribosome – tiny organelles that link amino acids together to form proteins
heterocyst – A specialized nitrogen-fixing cell that is formed by some filamentous cyanobacteria.
The combining form that means self is
How do monosaccharides, glycerol, fatty acids and amino acids get into the blood? – In the small intestine where they diffuse into the lining and into the blood.
Altered ecosystem – An ecosystem that has been relatively stable for a period of time that is suddenly changed and becomes unbalanced, either through natural events or human activities.
The cоmbining fоrm thаt meаns self is
Atom – The smallest particle of an element that still retains the properties of that element.
Carpel – The female reproductive organ of a flower, consisting of the stigma, style, and ovary.
When people put the data from scientific research together to explain a phenomenon, they are… – developing a model.
microorganisms – living things that can only be seen with a microscope (ex: bacteria, protists)
Store water, nutrients, and other materials; support plant cells – Vacuoles
