What changes are taking place in a wastewater bioreactor

Biology
1 answer:
Semenov [28]3 years ago
4 0

Answer:A membrane bioreactor (MBR) is a promising wastewater treatment technology, but there is a need for efficient control of membrane fouling, which increases operational and maintenance costs. Soluble microbial products (SMP) have been reported to act as major foulants in the operation of MBRs used for wastewater treatment. In this study, SMP in MBRs operated with different sludge retention times (SRTs) were investigated by means of various analytical techniques and their relations to the evolution of membrane fouling were considered. Bench-scale filtration experiments were carried out in a laboratory with synthetic wastewater to eliminate fluctuations that would occur with the use of real wastewater and that would lead to fluctuations in compositions of SMP.

Which clinical manifestation, when found in newborns, may indicate the presence of cystic fibrosis?

Meconium ileus, in newborns, may indicate the presence of cystic fibrosis

Cystic fibrosis is a genetic disorder mainly associated with cells capable of producing mucus. These cells are found in sweat glands, digestive system and lungs belonging to respiratory system. Thus, the abnormality in mucus production, in sticky and thick nature, disrupts the normal functioning of human body. They block the ducts and tubes, which can result in life threatening condition.

The mutation responsible for cystic fibrosis occurs in the gene CFTR, which is abbreviated form of Cystic fibrosis trans membrane conductance regulator. The primary function of gene is to regulate the exchange of fluids and salts present in the cells.

Meconium ileus refers to the inability of bowel movement in the newborn. This occurs due to thick and sticky mucus, which is indicative of cystic fibrosis, as discussed above.

This family of bacteria is often associated with urinary tract infections?
Colt1911 [192]

Answer:

The correct answer is C) Proteus

Explanation:

Proteus comes under the family <em>Enterobacteriaceae </em>and is often associated with urinary tract infections in animals and humans. These bacteria are often the part of intestine but become pathogenic when enter into urinary tract.

<em>Proteus mirabilis</em> is a gram negative anaerobic bacteria present as normal flora of intestine known to cause urinary tract infections in humans but most of the urinary tract infection is caused by <em>E. coli.</em><em> </em>

When these bacteria get into the blood stream they can cause systemic inflammatory response syndrome and sepsis which has very high mortality rate.

In what ways do prevailing winds affect precipitation in a region
BartSMP [9]

Answer:

Prevailing winds influence the precipitation by regulating amount of water vapor in air, direction of wind movement and by making cold and hot air masses to move.

Explanation:

Winds make both hot and cold air masses to move. The hot air rises up with wind and cold air rushes to take its place. The hot air coming from water bodies towards the land carry ample of water vapor and causes precipitation in the region. On the other hand, the air coming from land masses does not have enough water vapor to cause any rains in the region.
