Answer: Abiotic factor for polar: Ice
Abiotic for desert: Sand
Biotic for polar: Polar bears
Biotic for desert: Cacti
The types of factors are different because there are different set conditions for each ecosystem. A cactus is built for it's hot, dry ecosystem. If it were to move to a polar ecosystem it would not survive there. Same for the polar bear. It's built for polar regions. It has white fur to blend with the white ice to help it blend in and it's adapted to swim to get it's food source.
Explanation:
Answer:
Plant cells have cell wall but animal cell doesn't
Plant cells have chloroplast but animal cell doesn't
Plant cells has large vacuole but animal cell has smaller vacuole
Answer:
requires that mitochondrial ATP synthesis and electron flow through the respiratory chain be obligately coupled.
Explanation:
The chemosmotic model was a concept formulated by Peter Mitchell, who stated that during the phases of electron transport in the respiratory chain, an intense release of energy occurs. This released energy allows hydrogen ions to be transported from within the mitochondrial matrix to the intercellular medium. The result of all of this is the occurrence of a chemosmotic gradient. However, when interpreting what occurs in the chemosmotic model, we can see that this model requires that the mitochondrial synthesis of ATP and the flow of electrons through the respiratory chain must be coupled.
The abiotic factor that is essential for all aquatic ecosystem with the exception of hydro thermal vent is SUNLIGHT, THIS IS BECAUSE IT PROVIDES A SOURCE OF ENERGY.
Sunlight is very essential for aquatic ecosystems because it is the principal source of energy from which aquatic plants trap energy to make their food and provided mean of sustenance for themselves and other organisms in the water.
Answer:
Marine life, or sea cratures, or water creatures, or water type creatures.
Explanation:
Emphasis on SEA and I know starfish are also in the SEA.
