Answer:
Yes. Bacteria and Bacterium is a member of a large group of unicellular microorganisms which have cell walls but lack organelles and an organized nucleus, including some which can cause disease
Answer:
A. Their bodies tend to take in too much water.
Explanation:
Osmoregulation is the maintenance of osmotic concentration inside the body cells and in the extracellular fluid by controlling the amount of water and salts. Organisms living in water can be divided into two groups: Some are osmoconformers which change the osmolarity of body fluids with respect to the surrounding medium. Some are osmoregulators which do not allow change in internal osmolarity and try to maintain it by various means.
If as osmoregulator is placed in fresh water environment then their body is hypertonic to their environment. Osmosis will occur which is the movement of water from low solute to high solute concentration. Thus the problems faced by such organisms would be:
- Entry of excess water
- Loss of body salts to outside.
Adaptations in such organisms would be:
- Body cover such as scales or adipose covers
- They do not drink more water
- Excess water is eliminated as dilute urine
- Special cells called ionocytes or chloride cells help in active uptake of sodium ions and chloride ions.
Answer:
It depletes resources until there are no longer enough to sustain the population
Explanation:
Water enters the atmosphere through transpiration (from water of plants, giving off water vapor from pores of leaves), and evaporation (heated water changes into water vapor and rises into the atmosphere).
Remember to search the water cycle online, look at pictures, and do a bit of studying on your own. This will help you understand the water cycle to the next level.
I hope this helped!
