Cells are small because at their size, the ratio of surface area to volume is most efficient.
They are used in direction of animals

Hello your question is incomplete attached below is the complete question
answer :
23) The concentration of water in the beaker = 75% i.e. : 100% - 25%
24) The Bag is Hypotonic to the Beaker ;
25) The Beaker is Hypertonic to the Bag
26) The direction in which the water will move is from the Bag to the Beaker
27) the Bag will shrink
28) The movement of salt and water will continue until the concentration of the beaker and the bag is equal
Explanation:
23) The concentration of water in the beaker = 75% i.e. : 100% - 25%
24) The Bag is Hypotonic to the Beaker ; this is because the extracellular fluid ( Beaker ) has a lower concentration than the fluid inside the cell ( bag ),
25) The Beaker is Hypertonic to the Bag ; This is because the extracellular fluid( Beaker ) has a higher concentration than the cell’s cytoplasm ( bag ),
26) The direction in which the water will move is from the Bag to the Beaker
27) The condition that will occur if too much water moves out is that the Bag will shrink
28) The movement of salt and water will continue until the concentration of the beaker and the bag is equal
Hi!
I would say C, weak, dead, or partial antigens because do you need to be introduced to the disease for your body to fight it.
Hope this helps!
Answer:
Increases
Explanation:
The concentration of mercury will increases as it moves up the food chain because of biomagnification. For example, a school of small fish consumes a minute amount of mercury each, but then a larger fish eats five of the smaller fish. After this the larger fish has more mercury in its system than one small fish because it ate five small fish (along with the mercury in each of the small fish). Now a seal eats multiple large fish. Overall, the seal has the highest mercury concentration out of all the animals mentioned.
Biomagnification is "the concentration of toxins in an organism as a result of its ingesting other plants or animals in which the toxins are more widely disbursed."
