Chapter 1
A cell lacking a nucleus is called this:
What is prokaryotic, or prokaryote?
Sodium, a cation, forms ionic bonds with chlorine, which is this type of ion.
What is an anion?
Between liquid water and frozen water, this type is more dense.
What is liquid water?
This is an organic molecule consisting of carbon and hydrogen.
What is a hydrocarbon?
This type of lipid forms bilayers in water.
What is a phospholipid?
This branch of biology is concerned with the naming and classification of organisms.
What is taxonomy?
Chlorine has 17 protons, 17 neutrons, and 17 electrons, so this is its atomic number.
What is 17?
Cohesion and adhesion occur due to these types of bonds.
What are hydrogen bonds?
The atomic number of oxygen is 8. It takes this many electrons to fill the valence shell:
What is two?
The most common monosaccharide.
What is glucose?
This is the universal genetic language, common to all living beings.
What is DNA?
This bond is formed when two pairs of valence electrons are shared.
What is a double covalent bond?
OH- is called this type of ion.
What is a hydroxide ion?
This type of isomer often has one form that is biologically active and one form that is not.
What is an enantiomer?
Subjecting proteins to high temperatures can lead to this.
What is denaturing?
This is the reduction of a broad topic to simple components so as to best study the topic.
What is reductionism?
These bonds form between two equally electronegative atoms.
What are nonpolar covalent bonds?
This is the pH of a solution with a hydrogen ion concentration of 10-6 M.
What is pH 6?
A carbon atom with this type of bonding is often in a planar configuration.
What are double bonds?
This form of starch is unbranched.
What is amylose?
When running a scientific experiment, this is the variable manipulated by the researchers.
What is the independent variable?
This is the number of valence electrons in sulfur, with an atomic number of 16.
What is six?
Coca Cola has a pH of 3. What is the hydroxide ion concentration of Coca Cola?
What is 10-11 M?
What is form four covalent bonds?
This DNA base always pairs with guanine.
What is cytosine?
