A molecule of water is bonded with another molecule of water by what type of bond? - Hydrogen
Which is a benefit of the intermolecular hydrogen bonding of water: - 1- Water has a relatively high specific heat value.
2- Water has strong cohesive and adhesive properties.
3- Polarity of water allows it to act as a versatile solvent.

Lipids are better known as fats but what are they specifically? - Fatty acids, phospholipids, steroids
What are the 2 categories of fatty acids? - saturated fats and unsaturated fats
How do phospholipids function in cells? - They are integral components of plasma membrane

Which of the following proteins catalyze different reactions or processes? - Enzyme
Which of the biologic molecules are components of the molecules of inheritance? - Nucleic Acids
What is the sum of all chemical reactions that occur in an organism? - Metabolism
In a cell, reactions take place in a series of steps called: - Metabolic pathways
What is the fundamental unit of biology? - Cell
Which type of cell contains no defined nucleus? - Prokaryotic cell
What is the primary purpose of the flagella on the surface of cells? - movement of the cell
Which cell organelle functions to transport materials from the endoplasmic reticulum throughout the cell? - Golgi apparatus
Which are the distant organelles that produce cell energy? - Mitochondrion and chlorophast
Which component of the cell contributes to the protection, communication, and passage of substances into and out of the cell? - Cell Membrane
The Cell Membrane consists of a bilayer of phospholipids which proteins, cholesterol, and glycoproteins. The bilayer creates a hydrophobic region between two layers of lipids, making it what: - Selectively permeable

Which describes how a bacterium reproduces: - Binary fission
Regarding mitosis and cytokinesis, one difference between higher plants and animals is that in plants: - A cell plate begins to form at telophase
During which of the cell reproduction does the cell divide forming 2 separate identical cells? - Cytokinesis
How does Meiosis differ from Mitosis? - In Meiosis each of the daughter cells contain half as many chromosomes as the parent.
At which phase of meiosis does crossing over occur? - Prophase 1 [Show Less]
