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

E.Coli Strain

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?

Protists

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?

Eukaryotic Cells

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

Water Molecular Structure, Protists and Eukaryotes

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

Deviation in color of E.coli colonies after exposure to UV light.

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

Microbiology and Human Genetics

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.

Types of Cells

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 - eukaryotic cells have evolved into multicellular organisms

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

Why only Eukaryotic cells have evolved into multicellular organisms.

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

Study guide help

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

Help With Analyzing Research

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

Microbiology

#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

Discussion on Prokaryotic and Eukaryotic Cells

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

Activities of Enzymes

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.
