True I think hopefully it’s right!!
Answer:
The respiratory system's main job is to move fresh air into your body while also removing waste gases.
Explanation:
Your lungs are part of the respiratory system, a group of organs and tissues that work together to help you breathe.
True.
Precipitation is a water cycle process that happens when tiny droplets of liquid falls from the atmosphere it was settling. The hydrogen and oxygen mix back together and forms the water droplet altogether as it falls.
The water cycle involves other process from evaporation, condensation and precipitation.
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.
