Answer:
The diameter of the xylem vessels should be small in order for the capillary action to take place.
Explanation:
The vessels through which water is transported to different parts of the plants and trees are the xylem. Water is transported in the trees through a mechanism named as capillary action. This mechanism can occur only if the diameter of the vessels are small.
The water molecules adhere to the walls of xylem and an upward force is generated. If the diameter of the vessels i.e xylem would be small then the surface tension between the xylem and water molecules would be enough to move the water in an upward direction.
Bacteria in a unicellular organism that has an archaic structure but is very smart, specifically in antibiotic resistance.
Bacteria have several characteristic or "weapons" to fight antibiotics:
Bacteria has a cell wall which do not allow toxic substances to go in.
Bacteria has transporters which expulse the antibiotic molecules that enter into the cell.
Bacteria has enzymes that break the antibiotic molecules and make them inactive
Bacteria can mutate (change) itself so, and by the way the antibiotic sites, so the molecules cannot fix it. And that is the most problematic.
Bacteria can transmit it resistance mechanism to other bacteria, even if they are not from the same family.
The correct answer is 3- <span>The smelt and alewife may out-compete the native fish by consuming all of the zooplankton.
The diagram tells us that zooplankton is eaten by smelts and alewifes. If these two species increase in number, less of the zooplankton will be left for plankton-eating fish, which is a native type of fish, to eat.
</span>
<span> smelt and alewife eat most of the existing plankton so, they are out-competing the native fish.</span>
