AP Biology: Macromolecules Questions and Answers Graded A Macromolecules Molecules composed of thousands of atoms: the four main classes being carbohydrates, lipids, prteins, and nucleic acids Polymer Chainlike molecules, consisting of many similar or identical building blocks linked by covalent bonds. Monomer Make up polymers: connected by covalent bonds. Dehydration Synthesis (Condensation Reaction): Covalent bonds which connect monomers have distinct functions: One monomer provides a hydro...

Correct Answers There are two types of nucleic acids: DNA and RNA. There is both DNA and RNA inside the nucleus, mitochondria and plastids. Is there both DNA and RNA in the cytosol? Explain your answer - Answer No, not both. DNA remains in the nucleus. RNA copies of genes are synthesized in the nucleus, but then moved out pores into the cytosol, where ribosomes (also containing RNA) bind RNA and use the RNA to direct synthesis of proteins. In the case of plastids and mitochondria, RNA c...

Molecular & Cell Biology Questions With 100% Correct Answers Eukaryote - ANSWER- An organism whose cells contain complex structures enclosed within membranes. The defining membrane bound structure thats sets them apart from prokaryotic cells is the nucleas or nuclear envelope within which the genetic material is carried. All species of large complex species are eukaryotes, including animals, plants and funghi. Euchromatin - ANSWER- This shows as pale areas in the nucleas under elect...

Classification of organisms correct answers Kingdom, Phylum, Class, Order, Family, Genus, Species Phylogenetic trees correct answers a branching diagram that represents a hypothesis about the evolutionary history of a group of organisms Types of microbes correct answers bacteria, archeae, fungi, molds, yeasts, protozoa, algae, viruses, multicellular animal parasites rRNA correct answers The RNA component of the ribosome, and is essential for protein synthesis in all living organisms. ...

Independent Variable - Answer The experimental factor that is manipulated; the variable whose effect is being studied. Placed on the x-axis (horizontal) on a graph. Dependent Variable - Answer The variable that is measured in an experiment. Placed on the y-axis (vertical) on a graph. Scientific theory - Answer Must be repeatable. Possible to be disproved and capable of change. Sampling and Sample Size - Answer Random sampling is the preferred, but isn't always possible. A large sample ...
