Answer:
1. Minimum viable population is the estimate of the fewest number of organisms a population needs to avoid extinction.
2. The measurement will most likely stay the same if the number of offspring each female in the population produces increases.
3. If the death rate increases, this measurement will most likely increase.
Explanation:
Minimum Viable Population:
- Minimum viable population is an ecological threshold that signifies the minimum number of individuals required to prevent the species from going extinct.
- MVP determines population conservation benchmarks.
- MVP also helps in keeping a population genetically diverse as a limited number of individuals present limited mating opportunities and therefore limited genetic diversity.
The fossils called homo floresiensis were dated to 18,000 yBP. H. floresiensis individuals stood approximately 3 feet 6 inches tall, had tiny brains, large teeth for their small size, shrugged-forward shoulders, no chins, receding foreheads, and relatively large feet due to their short legs. They made and used stone tools, hunted small elephants and large rodents, coped with predators such as Komodo dragons, and may have used fire.
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.
