Answer:
Prokaryotes lack an organized nucleus and other membrane-bound organelles.
Explanation:
Prokaryotic DNA is found in a central part of the cell called the nucleoid. The cell wall of the prokaryote acts as an extra layer of protection that helps maintain cell shape and prevents dehydration
The process is called <span>alcoholic fermentation or also known as Ethanol fermentation. </span>An anaerobic pathway that is transferred by yeasts in which straightforward sugars are changed over to ethanol and carbon dioxide. The procedure of liquor aging enables yeasts to separate sugar without oxygen and results in side-effects that people advantage from.
The correct answer would be: dependence on nonrenewable resources.
A nonrenewable resources are resources that cannot be readily replaced by natural means, such as fossil fuels (oil, natural gas). The use of these resources is not sustainable because their formation takes billions of years. The whole world is dependent on these non-renewable sources but they are becoming more scarce daily.
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 global air temperature increases after the volcanic eruptions. It has also been observed that this increase in air temperature causes lowered winter seasons, acid rain, haze, dust, and ash. This causes problems in breathing and other disorders in humans as well as animals.
