what mechanism do bacteria use to attach to dry/glass surfaces?
In this case, we are talking about bacterial adhesion where bacteria use structures called fimbriae which is a appendage shorter than a flagellums. This structures posses adhesins which is highly important for this process, allowing bacteria to withstand shear forces.
It is believed that microbes use hydrogen bonds to attach themselves to surfaces. What if these forces were covalent bonds? Contrast the pros and cons of using covalent bonds as a means of attachment to surfaces.
what Catabolic pathways do bacteria of the gut use?
(Quadric surfaces) Use the quadric surfaces handout on Canvas to answer the following. Do not use a graphing utility for this problem. i. Give the name of each of the surfaces below. ii. Identify the shape of the horizontal traces (parallel to the ry-plane). (Hint: these surfaces may be oriented differently than on the handout - for example, the equation -y = 2x² +522 describes an elliptic paraboloid that opens' along the negative y-axis, and the horizontal traces are parabolas.]...
What is the initial compound? Also, what is the mechanism?
Dry HCl, OH
2) An empty dry glass vial has a mass of 0.04361kg. When the glass vial is filled to the mark with water the vial has a new mass of 49.61g. The glass vial is then emptied and dried and filled with a new solution. When filled to the mark the vial has a mass of 46549mg. What is the density of the new solution? (5 points)
1.5), both surfaces of which are partly metallized to increase A glass plate (n their reflectivity, may form two virtual images due to reflections from its external and internal surfaces. What are the refractive indexcs in the two image spaces? (0.5p) What is the difference between thin-film interference patterns observed in the reflected and refracted lights from the same film? (0.5p) A metal ring with a radius a and a total resistivity R is placed in a magnetic field B...
5. The tight coupling of translation with transcription in bacteria makes possible what mechanism of gene regulation (e.g., at the trp operon) that is not possible in eukaryotes? Just name the mechanism.
Why do bacteria use different secretion systems to inject effector proteins into other bacteria and into eukaryotic cells?
A lens made from glass with an index of refraction of 1.66 had two convex surfaces, one with a radius of 30 cm and the other with a radius of 50 cm. What is the focal length of the lens if it is surrounded by air?
The lifespan of the Ebola virus on flat dry surfaces has a normal distribution with μ=926.6μ=926.6 minutes and σ=78.8σ=78.8 minutes. You monitor a random sample of size n=97. What is the mean of the distribution of sample means? μ¯x=μx¯= What is the standard deviation of the distribution of sample means? (Report answer accurate to 2 decimal places.) σ¯x=σx¯=
