Which bases pair in DNA? In the simulation below, build the strand that is complementary to the one shown. In this case, you are not replicating the strand but completing it. correct answer: Thymine Adenine Guanine Cytosine Cytosine Thymine Thymine Adenine Guanine Thymine To continue, click on the image that you think best represents how DNA normally looks in the cell. correct answer: First image Looking at the images, how many chromosomes are there in a typical human? correc...

What is the old term for the boundary between the two formations? - K-T Boundary What is the new term for the boundary between the two formations? - K-Pg Boundary Which of these characteristics can be used to distinguish bone fossils from rocks? Select all that apply: - Spongy layers surrounded by dense layers Contains pores Sticks to the tongue Now it's time to test the whole set of samples. Select the images that contain fossils and click Test to see if you are correct. You will be gra...

Do you think this process is the same for all cells? - No, because prokaryotic cells would need more complex processes due to the cell wall See if you can identify which steps should occur in binary fission below: - Two genetically identical cells are present DNA is copied in place Cell wall and membrane pinch closed DNA migrates to either side of cell See if you can order the images from the first to last step starting on the left. - Circle with one green circle insid

During your explorations of previous lessons, what four types of molecules did you find that make up the structural components of a cell? - Carbohydrates / Lipids / Nucleic Acids / Proteins Shown to the right are diagrams of each of the components you identified in your exploration. They, in turn, are made up of smaller pieces called atoms, connected by things called bonds. Identify in the graphic below which pieces you think are atoms and which you think are bonds. - 1. Bond 2. Atom Ato...
