LIST AT LEAST THREE EXAMPLES OF HOW MICROBIAL PHOTOTROPHS ARE IMPORTANT CLINICALLY AND ENVIRONMENTALLY

2 answers:

5 0

Microbial phototrophs are organisms like algae and cyanobacteria which carry out their cellular metabolic processes by using the energy from light.

These are important environmentally as they are present on the surfaces exposed to light in terrestrial as well as aquatic environments. Here, algae and cyanobacteria are the major primary producers of energy as they generate energy and reduce carbon dioxide. This helps to provide the environment with organic substances and oxygen.

Clinically the cyanobacteria has contributed to many aspects of human life like it is used for several medical purposes. Many Proterozoic oil deposits are attributed to the activity of cyanobacteria.

Cyanobacteria are primitive organisms where chloroplasts are believed to be originated. These phototrophic organisms benefit the environmental and the clinical aspects because of their unique physiology. For instance, they contribute to energy attainment from sunlight which helps other organisms gain energy when this is consumed. Another is the contribution to biogeochemical cycles. And lastly, how these can aid in many medical discoveries and treatments.

The rigid layer that is present in the cell walls of bacteria that is primarily responsible for the strength of the wall is know

melomori [17]

The substance that helps keep the integrity of the bacterial cell wall intact is known as the peptidoglycan. Others also refer to is it as murein or mucopeptide. The bacterial cell wall is necessary for survival because of the high internal pressure present inside of bacteria. Under normal conditions, if the cell wall is removed the bacterial cell will burst.

The peptidoglycan is a layer that can be used to distinguish gram positive bacteria from gram negative ones. G(+) bacteria have a thick layer of this while G(-) have a thinner ones.

Complete Question:

You volunteer for a sleep study and the researchers discover that your blood oxygen level drops many times during the night. It is likely that you have

A) sleep-onset insomnia.

B) REM behavior disorder.

C) narcolepsy.

D) sleep apnea.

Correct Option:

It is likely that you have "sleep apnea".

Option: D

Explanation:

Sleep apnea is a disorder which is identified by frequent stoppage and breathing start while sleeping. This is due to extreme relaxation of the throat muscles that hinder the normal breathing mechanism leading to reduced blood oxygen levels (recognized as hypopnea).

Throughout a sleep study, the patient's oxygen level is tracked with a pulse oxymeter connected to the hand, finger as well as other parts of the patient. An individual with SA will get a decreased amount of air in inhalation due to irregular breathing patterns while asleep.

__________________ moves the respiratory medium over the respiratory surface.

Answer:

ventilation

Explanation:

Breathing, also known as ventilation, is the process of moving air or water in order to facilitate the gas exchange between the external and internal (body) environment, mostly to eliminate carbon dioxide (CO2) and bring in oxygen (O2). For example, fish are aquatic animals that need to run water over their gills to get the O2 that they need to survive (gills are organs that create a large surface area for ventilation). Moreover, insects ventilate their tracheal system to get O2. Finally, terrestrial vertebrates (i.e., amphibians, reptiles, birds, and mammals) use organs called lungs to exchange O2 and CO2 between their cells and the external environment.
