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.
Answer:
Multicellular organisms are made of more than one cell and are complex organisms.
They are visible to the naked eye.
They possess distinct organs and organ systems.
They are eukaryotes, i.e., they contain membrane-bound structures.
Their cells exhibit division of labor.
Their size increases with the number of cells in an organism
Explanation:
Answer: DNA
Explanation:
DNA also referred to as deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Almost every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus.
Increases. With more food available for the secondary consumers, theres less competition for food. This means the secondary consumers can breed successfully with high chance of offspring survival
