The simplest structure shared among all living things is the
Cell
Maintenance of constant body temperature and pH are examples of
Regulation and homeostasis a variety of finch species within the islands have acquired different types of beaks needed for utilizing specific food resources. This is an example of which property of living things
Evolutionary adaption
The three domains of life are called
Bacteria, archaea and eukarya
The grouping or classification of species is termed
Taxonomy
We are called homo sapiens. The first word in this scientific name refers to which grouping
Genus
An explanation of a biological process that is substantiated by a large body of evidence is called a
Theory
The center of an atom is called the
Nucleus
The nucleus contains both
Protons and neutrons
The negatively charged particles surrounding the center are called
Electrons
(3^H), an isomer, differs from (1^H) in that:
3^H has 2 more neutrons than 1^H
Nitrogen has 7 electrons and thus can form a maximum of ___ covalent bonds with other elements
3
Carbon has 6 electrons while hydrogen has 1 electron. How many covalent bonds can form between a carbon atom and hydrogen atoms

In the lab you are culturing human cells in order for the cells to survive they must be cultured in a solution containing 25 mM glucose. You must make 500 ml of this solution. First, calculate the molecular weight of glucose given that its molecular formula is C6H12O6 (C=12g/mol, H=1g/mol, O=16 g/mol). The molecular weight of glucose is:
180 g/mol
How many grams of glucose should you weigh out and add to 500 ml to make a 25 mM solution
2.25 g

Your final solution has a [H+] = 3.98x10^-8 what is the pH of the solution? pH= 7.4
Carbon and nitrogen have dissimilar electronegativities. When these atoms combine together what type of bond forms between them
Polar covalent
What type of bond is formed from the transfer of electrons between elements
Ionic
How many chloride atoms (A# 7) will bond ionically to one magnesium atom (a# 12) to form the salt magnesium chloride
2
Small amounts of blood are often collected in a capillary tube. What is the property of water that allows it to be easily drawn into the capillary tube?
Cohesion and adhesion
Buffers are molecules that
Minimize fluctuations in the pH of solutions
Are usually weak acids and bases
Are common in biological fluids
Limit major shifts in the amount of H+ and OH- in solution
If you added a strong acid like HCI to an unbuffered, aqueous solution what would happen
Both the H+ would be released into solution and the pH would decrease
If a specimen contains 30% adenine in its DNA then how much cytosine will there be
20%
What level of protein structure is most directly affected by this single amino acid mutation
Primary
Which of the following molecules is nonpolar
C2H6
Which types of bonds contribute to the folding of proteins
Hydrogen bonding
Electrostatic interactions (between charged amino acids)
Van der waals interactions
Covalent bonds
