What is a microscopic acellular agent composed of nucleic acids surrounded by a protein coat?
A virus is a microscopic acellular agent composed of nucleic acids surrounded by a protein coat. It is not considered a living organism as it cannot replicate or metabolize on its own, relying on a host cell for these functions.
What cannot metabolize nutrients?
Non-living entities such as rocks, air, or water cannot metabolize nutrients as they lack the necessary biological processes and machinery to utilize and break down organic molecules for energy. Metabolism is a characteristic of living organisms that enables them to convert nutrients into energy through various biochemical pathways.
What is the uncertainty of the position of the bacterium?
The uncertainty of the position of a bacterium can be very small, on the scale of micrometers to nanometers. This uncertainty is known as the positional accuracy and can be influenced by factors such as the resolution of the imaging technique used to observe the bacterium and the movement of the bacterium itself. Advanced microscopy techniques like super-resolution microscopy can improve the positional accuracy of tracking individual bacteria.
Can the fetus metabolize glucose without oxygen?
First of all, the human fetus does have oxygen. The oxygen is obtained from the mother's blood via the placenta. But if the fetus did not have oxygen temporarily, s/he could still metabolize glucose. This would be done the same way that other humans metabolize glucose without oxygen--by converting it to lactic acid.
What makes sinks turn pink?
Pink staining in sinks can be caused by a bacterium called Serratia marcescens, which thrives in damp or wet environments. This bacterium often appears pink or pinkish-red in color and can grow on different surfaces, including sinks, showerheads, and grout. Proper cleaning and maintenance can help prevent the growth of this bacterium.
How do Pathogenic bacterium metabolize its host?
The bacterium secretes enzymes that break down organic structures.
Who can metabolize lactose?
types of bacterium.
Does the bacteria tetanus need a host to survive?
No. The bacterium Clostridium tetani forms an endospore and can survive for long periods of time. When the endospore is introduced into a favorable environment it begins to metabolize.
A bacterium that can enter the structure of a host cell is called?
intracellular.
Is a host a living thing as in cells?
Yes, the host is living, whether it be a host for a virus, a worm, or a bacterium.
Where in a host cell does hidden virus hide while it is inactive?
bacterium
The lac operon enables a bacterium to build the proteins needed for lactose metabolism only when what is presented?
Only when lactose is present; if glucose is present the cell will metabolize glucose over lactose due to glucose being easier for the cell to metabolize.
What is a disease producing agent especially a virus or bacterium called?
A micro-organism, such as a bacterium, a virus or a fungus, that invades a host and causes a disease is called a pathogen.
What tick is an intermediate host for borrelia burgdorferi?
The deer tick (Ixodes scapularis) is an intermediate host for Borrelia burgdorferi, the bacterium that causes Lyme disease. The bacterium is transmitted to humans through the bite of an infected deer tick.
What is lysogenic conversion?
Lysogenic conversion occurs when a bacteriophage integrates its DNA into the host bacterium's genome during the lysogenic cycle. This can lead to the insertion of new genetic material that may alter the phenotype of the host bacterium, such as providing new traits or making the bacterium pathogenic.
Explain how lipid hydrolysis can be correlated with the pathogenicity of a bacterium?
A very loose correlation can be made between breaking down gelatin and the ability to breakdown tissue. The scientific process can only be replicated within a lap environment but with the constant evolution of bacterium it is possible at some point for the gelatin and tissue correlation to be much stronger.
What kind of cell does a phage infect?
A phage infects bacterial cells by injecting its genetic material into the host bacterium. Once inside, the phage hijacks the bacterium's cellular machinery to replicate and produce more phage particles, ultimately leading to the bacterium's destruction.
