Water.
osmosis always refers to the diffusion of WATER down a concentration gradient.
diffusion can be applied to any substance;
osmosis only applies to the diffusion of water.
in the situation described, osmosis occurs by water diffusing out of the plant, down the diffusion gradient (because the salt water effectively has a lower concentration of water than in the plant) and into the salt water.
Danish scientist Hans Christian Gram devised a method to differentiate two types of bacteria based on the structural differences in their cell walls. In his test, bacteria that retain the crystal violet dye do so because of a thick layer of peptidoglycan and are called Gram-positive bacteria. In contrast, Gram-negative bacteria do not retain the violet dye and are colored red or pink. Compared with Gram-positive bacteria, Gram-negative bacteria are more resistant against antibodies because of their impenetrable cell wall. These bacteria have a wide variety of applications ranging from medical treatment to industrial use and Swiss cheese production.
Answer:
b. actively transport Cl- from the ECF to the external environment.
Explanation:
Chloride cells are cells that are found in the gills of teleost fishes which pump large amount of sodium and chloride ions out from the extracellular fluid (ECF) into the sea or environment against a concentration gradient in marine fish.
The opposite of this process occurs in freshwater fishes where the gills of freshwater teleost fish, cause an influx of sodium and chloride ions into the fish from the environment, also against a concentration gradient.
Mechanism of action
Salt water teleost fishes take in large amounts of seawater to decrease osmotic dehydration. The excess of ions derived from seawater is thrown out of the teleost fishes through the chloride cells. These cells employs active transport on the basolateral (internal) surface to diffuse in chloride, which then is pumped out of the apical (external) surface, straight into the surrounding environment. Such mitochondria-rich cells are located in the region of the gill lamellae and filaments of teleost fish.
The procedure of dialysis maintains the body in balance by withdrawing waste, extra water, and salt by preventing them from accumulating up in the body when the kidneys fail. It helps in maintaining a safe level of some kinds of chemicals in the blood, like sodium, potassium, and bicarbonate. It helps in monitoring blood pressure.
Hence, dialysis helps in performing a function for the circulatory system of the body.
