Enzyme saturation is the term for the point at which an increase in the concentration gradient no longer speeds up the reaction rate

Explanation:

At this point, the rate of reaction does not increase with an increase in the concentration of the substrate. This is because all the active sites of the enzymes are occupied by substrate and the enzyme concentration subsequently becomes the limiting factor in the reaction. Therefore the only way to increase the rate of reaction is by increasing the concentration of the enzyme.

Elden [556K]

Answer:

There can be many different limiting factors at work in a single habitat, and the same limiting factors can affect the populations of both plant and animal species. Ultimately, limiting factors determine a habitat's carrying capacity, which is the maximum size of the population it can support.

A commensal bacterium?
Otrada [13]

Answer

Commensal bacteria stimulate the immune system of the host to enhance defense mechanisms that block pathogen entrance and colonization.  Moreover, by creating antimicrobial properties and signals & fighting with other bacteria for food and attachment sites, such bacteria might effectively limit the spread of respiratory infections. In healthy animals, the majority of commensal bacteria live inside the intestine's lumen, although some are also found in immediate contact with the intestinal epithelium. New studies have shown that commensal bacteria may live in stable stomach lymphoid tissues. But every once in a while, especially when they travel to other areas and leave their natural habitat, these commensal bacteria might cause illness. In both old and very and also in young persons, it can spread throughout the rest of the body, causing pneumonia, infection, and meningitis.

Virtually all cells in the human body have the same DNA. What’s make some undifferentiated cells differentiated into brain cells
mariarad [96]

Answer:

Changes in gene expression

Explanation:

This phenomenon is the result of changes in gene expression. That means, how the information in the DNA is used by the cell. The genes that are active in the cells of the brain will be very different from the genes that are active in the cells of the bone marrow.

These patterns of gene expression are different for each cell, and dictate the identity of that cell. Gene expression patterns are controlled by a variety of factors in the cell that allow tissue-specific expression, such a transcription factors.

This can also be facilitated by another layer of regulation called epigenetics, which literally means "on top of" genetics, and refers to modifications of DNA (and the proteins around it), that can reflect and influence the activity of the genes within.

Typically, urea broth is filter-sterilized because autoclaving breaks down the urea. However, even unsterilized broth rarely pro
Anni [7]

Answer:

When organisms use urea, ammonia is generated during incubation, which makes the reaction of these media alkaline

Explanation:

Urea broth preparation:

Suspend 3.87 grams of the medium in 100 ml of distilled water without heating. When the powder dissolves, sterilize by filtration. Dispense quantities of 0.5 to 2 ml in small sterile tubes. Larger volumes may be used but the reactions will be slower. Do not sterilize in autoclave.

Do not boil the medium.

If no filter is available, the medium can be sterilized at 100-110 ° C for 10 minutes. If the medium is prepared and inoculated immediately, it provides good results without sterilization.
