Below is the electron configuration of a carbon atom.  Based upon that please predict the type of bonding that would take place with a carbon atom.   Accessible description of image:  Diagram of a carbon atom showing a central nucleus labeled “Carbon,” made up of clustered protons and neutrons. Surrounding the nucleus are two dashed circular electron shells. Two electrons are shown on the inner shell (labeled “S”), and four electrons are shown on the outer shell (labeled “P”), illustrating carbon’s six total electrons.

Scenario Kenneth and Catherine Lohmann of the University of North Carolina explored the orientation ordirection-finding abilities of loggerhead sea turtle hatchlings under varying magnetic conditions.Hatchlings were placed in a tank of water in a laboratory either in the natural magnetic field ofthe earth OR in a reversed magnetic field in which north and south were flipped. Theresearchersthen measured the direction that the hatchlings swam. The experiments were carried out in thedark and at night since that is when most newly hatched turtles migrate from their sandy nestsinto the ocean. In the experiment, hatchlings swam in one direction when exposed to the natural magneticfield of the earth, but in a different direction when exposed to the reversed magnetic field? Whatconclusion can be drawn from this?

Use the figure to answer the following question. If two or more of these molecules are in proximity to one another, how will they bond together?  Accessible description of image: Diagram of a water (H₂O) molecule showing one oxygen atom in the center bonded to two hydrogen atoms in a bent (V-shaped) arrangement. The oxygen atom is labeled with a partial negative charge (δ−), and each hydrogen atom is labeled with a partial positive charge (δ+). Small “e−” symbols near the oxygen indicate shared electrons in the covalent bonds. Arrows point toward the oxygen atom, illustrating the direction of electron density and the molecule’s polarity.  

Match the letters indicated in this graphic with the correct label.  You are only asked to answer for the letters indicated, not all of the letters.   Accessible description of image: Image of a cell and its various components with counter-clockwise letters going from a through n.

Which enzyme is most directly responsible for mutations in DNA?

Which of the following is the correct sequence of how an animal is “built”? 

What can you conclude from the data in the graph?

DNA profiling is used to unambiguously identify individuals based on their DNA sequences. To produce a DNA profile, a person’s DNA is analyzed at 13 specific sequences that are known to vary in length between different individuals. The DNA is then separated by size on an agarose gel, producing a banding pattern specific to that person.Use this DNA profile of two individuals to answer the question. Accessible description of image:  The DNA banding pattern after having been run on an agarose gel showing the DNA profile for two different individuals.    Do these two different individuals share any bands of the same length? Why might this be the case?  

Your interest is piqued by a story about human pheromones on the news.  A Google search leads you to the following website. Accessible description of image:  The screenshot includes a link to a website, EROS Foundation that makes various health claims.   For this website (EROS Foundation), which of the following characteristics is MOST IMPORTANT in your confidence that the resource is accurate or not.  

Years ago, farmers determined that suppressing flower development in the wild mustard plant gave rise to the plant we know as broccoli. This is an example of:
