Answer:
more nitrogen compounds
Explanation:
when water is polluted by sewage many microorganisms is present so we can deduct the 1st ans.
as water is polluted the environment is not suitable so living organisms so unpolluted water has more fish than polluted.
there cant be more oxygen in a place where it s polluted coz plants which grow under water wont grow as it is polluted
more nitrogen compounds is the answer because nitrogen compounds are made due to the reactions in polluted water.
hope this helps,
Answer:
The correct answer is: a) osmosis.
Explanation:
- Osmosis can be defined as the physiological process by which molecules (in this case water) tend to move from a region where their concentration is high to a region where their concentration is low by the process of diffusion across a semi-permeable membrane.
- Active Transport can be defined as the physiological process in which molecules are forced to move from a region where their concentration is low to a region where their concentration is high across a semi-permeable membrane. This process requires the expenditure of energy and is usually mediated by carrier proteins or integral membrane proteins which span across the plasma membrane.
- Filtration can be defined as the physical process by which insoluble solute molecules are separated from the solvent molecules by the help of a porous filter paper which allows the solvent molecules to pass through it but restricts the insoluble solute molecules from passing through it.
- Diffusion can be defined as the physical process by which molecules tend to move from a region where its concentration is high to a region where its concentration is low. However, unlike osmosis, there is no semi-permeable membrane which separates the two regions.
It was commonly understood in the past the dogs come from a lineage of wolves, but that isn't the case now. Scientists have found out that dogs and wolves come from a common ancestor about 9,000 to 36,000 years ago. This was done through extensive DNA analysis with samples that took into consideration the geographic locations of their origin and of modern isolation. This yielded a result that despite geographical difference, the dogs are more closely related than to wolves. It is now understood that the complication of the genetic relationship between the two was caused mainly by interbreeding during the course of time, but it isn't just that. Some other factors have come into play including the presence of humans.
