The substances that will conduct electricity is the NaCl solution. Sodium chloride in its solid form do not conduct electricity since the compound is stable and bonded well so there are no available charge carriers. However, when this salt is dissolved in water, it ionizes or dissociates into sodium ions and chloride ions. On the other hand, solid sugar and an aqueous solution of sugar do not conduct electricity since the bond involved in this compounds is covalent, no ionization would occur. When sugar is dissolved in water it stays as a molecule so there will be no available charge carriers to let electricity flow.
Answer:
According to an energy pyramid model, Producer is expected have the largest biomass in land ecosystems
Explanation:
In a trophic level, the producers possess the largest biomass. With the increasing trophic level, the biomass reduces. Hence, the producers at the base have high biomass.
On terrestrial ecosystem, the producers are the plants and trees and hence the greatest biomass exists in the plants and trees.
Hence, in an energy pyramid model, Producer is expected have the largest biomass in land ecosystems
Answer: Lysosomes
Explanation: The lysosome is an organelle that contains digestive enzymes and acts as the organelle-recycling facility of an animal cell. It breaks down old and unnecessary structures so their molecules can be reused. Lysosomes are part of the endomembrane system, and some vesicles that leave the Golgi are bound for the lysosome.
