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.

Located on the basilar membrane are(is) the <u>organ of Corti</u><u> </u>containing hair cell sensory receptors for the sense of hearing.
The organ of Corti is also called basilar papilla which is a complex form of neuroepithelium composed of hair cells sensory receptors and supporting cells. In addition to these sensory and supporting cells, the organ of Corti also consists of a tectorial membrane. Endolymph which is a potassium-rich fluid surrounds the organ of Corti. The organs known as scala tympani and scala vestibule are present under and above the basilar papilla respectively.
The function of the organ of Corti is to generate electrical signals based on the sounds and transmit these signals to the brainstem through the passage of auditory nerves.

Write a new hypothesis and conduct new experiments to explore the matter. Thus, option "B" is correct.
<h3 /><h3>What is the Hypothesis?</h3>
Hypothesis
The formulation of hypotheses is one of the key steps in the scientific method.
Hypotheses are usually tested using experiments and are usually accepted or rejected depending on the outcome of the experiments.
If a hypothesis is rejected, it does not mean that the entire subject is abandoned. Rather, new hypotheses may be formed and experiments conducted to further explore the subject.

Answer:
A. Outer Membrane B. Peptidoglycan C. Cytoplasmic Membrane
Explanation:
I can't really give an explanation for this one but if you look up gram negative bacteria and go to images you can find a photo that is very similar to the one you show that has labels.
Answer:
It is a facultative anaerobic organism.
Explanation:
This organism makes ATP (energy provider molecule) by aerobic respiration in presence of oxygen, but when oxygen is removed it is capable of switching to fermentation (sugar consumption increases and growth rate decreases).
This happens because fermentation is much less effective at producing ATP and therefore there is not enough energy for growth.
This organisms are called facultative anaerobic.
Organisms with this type of metabolism include bacteria like Escherichia coli and Salmonella or yeast like Saccharomyces cerevisiae.
