Answer:
The correct answer is - a hypotonic solution as it can pass the cell wall and cell membrane into the cell.
Explanation:
The plant cell has a rigid cell wall that provides support to the plant cell that is not the case in the animals as they lack the cell wall. The low tidewater is an example of the hypotonic solution as it has fewer solutes than the plant cells or animal cells.
When a plant cell is in freshwater it takes up the water with the help of osmosis and begins to swell but the cell wall does not let it burst and become turgid.
Thus, the correct answer is - a hypotonic solution as it can pass the cell wall and cell membrane into the cell.
Answer: C). A tsunami would decrease abundance by causing physical damage to the organisms and their ecosystems.
An intertidal zone is also known as littoral zone. It is the region which is covers the foreshore and seabed. This region is exposed to the affects of tides. This region is highly vulnerable to tsunamis. The tsunami will disturb the habitat of organisms living in intertidal zone. Therefore, will result in decrease in abundance of aquatic organisms.
The correct answer is a nutrient runoff.
Nutrient runoff is a major reason for eutrophication of surface waters, in which extra amount of nutrients, generally phosphorus or nitrogen, instigate growth of algae. Sources of nutrient pollution involve surface runoff from pastures and farm fields, emissions from combustion, and discharges from septic tanks.

The answer is pili. the specific type of pili that can exchange genetic information is conjugative pili. when bacteria exchange geetc information, this process is called bacterial conjugation. conjugative pili can also be named as sex pili because they also allow exchange of genes
