Macromolecules are polymers‚ built from monomers - Carbohydrates‚ proteins‚ and nucleic acids are all chain-like molecules called Polymers Polymer- is a long molecule consisting of many similar or identical building blocks linked by covalent bonds. Example: Much as a train consists of a chain of cars. Monomer- A subunit that serves as the building block of a polymer -Some molecules that serve as monomers also have other functions of their own. ----------------------------------------------

franciscana are known to live in high salinity lakes that are often basic (Biology 108 Lab Manual 2015). Furthermore‚ A. franciscana feed on photosynthetic phytoplankton which inhabit areas of light availability but are also more susceptible to predation in highly-lit areas (Biology 108 Lab Manual 2015). Also‚ A. franciscana can withstand a broad range of temperature except extreme values may affect survival (Biology 108 Lab Manual 2015). In this experiment‚ the habitat

Molecular Biology Lab Report Mapping DNA using Restriction Enzymes Ava II and Pvu II to cut Bacterial DNA Abstract The objective of this project is to map bacterial DNA‚ which is derived from E. coli‚ using restriction endonucleases with gel electrophoresis. The DNA fragments‚ after cutting has occurred‚ are separated using agarose gel electrophoresis. The DNA fragments are placed in the gel‚ and an electric current is run through the matrix of the gel-like agarose. Migration of the fragments

for operating the cell. The similarities go beyond visible things‚ as physiologically they are also very similar. An example of this is the DNA in the two cell types is precisely the same kind of DNA‚ and the genetic code for a prokaryotic cell is exactly the same genetic code used in eukaryotic cells. Other things in the two cells that may appear a difference aren’t‚ an example being prokaryotic cells have a cell wall‚ and while not all eukaryotic cells have a cell wall‚ many do including plant

The carrying capacity of a biological species in an environment is the population size of the species that the environment can sustain indefinitely‚ given the food‚ habitat‚ water and other necessities available in the environment. In population biology‚ carrying capacity is defined as the environment’s maximal load‚ which is different from the concept of population equilibrium. Population size decreases above carrying capacity due to a range of factors depending on the species concerned‚ but can

Biology 4U Exam Review Intro to Biochemistry Types of bonding: Ionic Results from the attraction between two oppositely charged atoms or molecules. They must lose or gain electrons to become charged. For example‚ a sodium molecule and a chlorine molecule form an ionic bond to create sodium chloride (NaCl) Covalent Results from the sharing of one or more pairs of valence electrons to create a stable molecule. For example‚ the covalent bonding of hydrogen ions creates hydrogen gas (H2)
