Many of the most devastating human diseases result from an attack of various microbes (viruses, bacteria, fungi) on the human body. The flu epidemic of 1918 killed 22 million Americans and Europeans in just 18 months, and our ongoing war against the HIV virus is still waging. In order to fight against this onslaught, the human b
You are a graduate student working on a followship for a biotech companny .You are part of a group that will perform some scientiific research. You recieve various soil samples shipped to you from remote areas of the world. You and your team members need to evaluate these samples
A nutritionally defective E.coli strain grows only on medium containing thymine, whereas another nutritionally defective strain grows only on medium containing leucine. When these two strains are grown together, a few progeny are able to grow on minimal medium with neither leucine nor thymine. How can this result be explained?
Protist is much more complex then cells of multiceller organisms. Does this mean that the Protist is engaged in more complex activities then multicellular organism and if not why should the Protistan cell be much more complicated?
Often, prokaryotic cells exist as simple unicellular organisms, but in some species, prokaryotic cells can grow together in colonies or filaments. In addition, some species, such as Cynaobacteria or Myxobacteria, demonstrate intercellular communication, or might even produce specialized cells and structures. However, only euk
1. Select a molecule. List the atoms that that molecule is composed of and describe the type of bond that holds those atoms together. Be sure to explain how this bond works. 2. Often, prokaryotic cells exist as simple unicellular organisms, but in some species, prokaryotic cells can grow together in colonies or filaments. In
What distinguishes a eukaryotic cell from a prokaryotic cell? Why embryos are an excellent source for stem cells? Why do cows have the ability to breakdown cellulose into glucose and humans can not digest cellulose?
We are suppose to explain what type of mutation could cause for color variation in certain colonies of E. coli. We first started off with one normal strand of the E. coli bacteria, and after UV light exposure we need to propose a theory of what typeof mutation could cause a single colony to mutate into 5 possible colors (white
Can microbiology assist human genetics? How the alkaptonuria (black urine disease) mutation was identified? Many of the processes that convert one material to another are common to many organisms. Some were preserved during evolution and they are similar among bacteria, plants, animals and humans.
Give the name for the type of cells that are simple in structure and are usually surrounded by a thick cell wall for protection and shape.
Bacteria never form any sort of grouping that resembles a multicelled organism with an internal division of labor among its cells. Think about the attributes of prokaryotic bacterial cells and the eukaryotic cells of which all multicellular organisms are comprised. Develop some hypotheses explaining why only eukaryotic cells hav

Nonmotile reproductive cells and multicelled structures, often walled; germinate following dispersal from the parent body. B. Represent major lineages of
What term refers to a cell that has no nucleus or membrane bound organelles, such as bacteria? a. prokaryotic b. eukaryotic c. planktonic d. pathogenic What term refers to a cell that has a nucleus and membrane bound organelles, such as plant and animal cells? a. prokaryotic b. eukaryotic c. planktonic d. pathogenic
1. Argue for or against the statement, "Viruses are alive." 2. The internal structure of many protists is much more complex than that of cells of multicellular organisms. Does this mean that the protist is engaged in more complex activities than the multicellular organism? If not, why should the protistan cell be much more c

Think about the attributes of prokaryotic bacterial cells and the eukaryotic cells of which all multicellular organisms are comprised. Develop some hypotheses explaining why only eukaryotic cells hav
Hi, I would like to have a study guide for my biology exam coming up this week. Could you find the answers to these questions? Please be sure that the answers are correct and take the full alotted time if needed. Complete the following multiple choice questions 4. Sponges cannot hunt their prey, cnidarians can. Cnidaria
I am conducting a yearlong research project where I am testing a new medication, telithromycin, against 4 different types of bacteria. I will then compare its activity to that of another medication, levofloxacin, that is already known to work against these 4 bacteria. I have measured zones of inhibition for each medication vs. e
#6 Macrophages perform the final job of removing tissue debris and other products of infection. Indicate some of the possible effect when these scavengers cannot successfully complete the work of phagocytosis. (1pt.) #11 A patient with chronic diarrhea was found to lack IgA in his secretions, although he had a normal leve
Bacteria never form any sort of grouping that resembles a multi-celled organism with an internal division of labor among its cells. Think about the attributes of prokaryotic bacterial cells and the eukaryotic cells of which all multicellular organisms are comprised. Develop some hypotheses explaining why only eukaryotic cells ha
Question: Activities of the following enzymes - protease, amylase, and lipase. I want detail on the activities of these enzymes in relation to food microbiology. I am not too sure how to approach this question.
Explain the differences between prokaryotic and eukaryotic cells.
Briefly describe the methods used by bacteria and fungi to tolerate environmental heavy metals. Include references and your views on the potential commercial applications of bacteria and fungi.
What are the similarities and differences between prokaryotic and eukaryotic cells?
