Answer:most protozoa (prevalently attached ciliates) can only graze on suspended bacteria and particles; in this way they have a significant effect on the effluent quality.
Explanation:Even though some protozoa (crawling ciliates and other forms) can eat flocculated bacteria, most protozoa (prevalently attached ciliates) can only graze on suspended bacteria and particles; in this way they have a significant effect on the effluent quality.
The Xylem is the vascular tissue that moves water up the plant. Phloem is the vascular tissue that moves food up or down the plant.
True
False I think it is true
The ozone layer keeps harmful rays from the sun also the atmosphere burns up small deburey from rockets, space trash ex. Also small rocks and particles can get burned before hitting the earth. One of the greatest things is it keeps spefic gasses needed for life like oxygen in the world.
Answer:
Water (H 2O) is a polar inorganic compound that is at room temperature a tasteless and odorless liquid, which is nearly colorless apart from an inherent hint of blue. It is by far the most studied chemical compound and is described as the "universal solvent" and the "solvent of life". It is the most abundant substance on Earth and the only common substance to exist as a solid, liquid, and gas on Earth's surface. It is also the third most abundant molecule in the universe.
Water molecules form hydrogen bonds with each other and are strongly polar. This polarity allows it to dissociate ions in salts and bond to other polar substances such as alcohols and acids, thus dissolving them. Its hydrogen bonding causes its many unique properties, such as having a solid form less dense than its liquid form, a relatively high boiling point of 100 °C for its molar mass, and a high heat capacity.
Water is amphoteric, meaning that it can exhibit properties of an acid or a base, depending on the pH of the solution that it is in; it readily produces both H and OH ions. Related to its amphoteric character, it undergoes self-ionization. The product of the activities, or approximately, the concentrations of H and OH is a constant, so their respective concentrations are inversely proportional to each other.
