Correct matching of invertebrates and its characteristics are as follows:
Sponges are animals which have many cell but no mouth, muscles , heart or brain. They are sessile and can not move from place to place like other animals do, filter feeding animals with an asymmetrical body plan.
Cnidarians are the animals with radial symmetry and stinging cnidocyte cells. These animals consists a special cell cnida which functions in preying catch and defense. example- jellyfish, anemone.
Flatworms are the worm like animal which do not consist a body cavity or coelom. example- fluke and tapeworms.
Roundworms or threadworms are segmented worms that can live in water or land. They consist a body cavity and internal organs. examples- pinworms and hookworms.
Mollusks are the animals which consist mentle, foot and and sometimes a shell. example- octopus, squids.
Echinoderms are the animals which have radial symmetry and an endoskeleton made out of calcareous plate. These animals live only in marine environment.These animals lack circulatory and excretory systems.
Arthopods are the animals with jointed legs and an exoskeleton made out of chitin. example- spiders, shrimps and crabs.

Answer:
Active Transport
Explanation:
Active transport is the process of transport of substances from region of their lower to that of higher concentration. Since the transport occurs against the concentration gradient, it is energy requiring process and needs input of energy to occur.
In given example, liver cells transports vitamins against the concentration gradient in energy dependent manner. Therefore, it is an example of "active transport".
Within the extracellular fluid, the significant cation exists sodium and the primary anion exists chloride.
<h3>What are the various chemical properties of nutrients in the body?</h3>
Chloride exists as a significant donor to the osmotic pressure gradient between the ICF and ECF and recreates an essential part of preserving proper hydration. It functions to balance cations in the ECF, preserving the electrical neutrality of this fluid.
Chloride exists by extensive the primary anion in the extracellular fluid. Its concentration in blood plasma exists around 98.00–107.00 (mM), in cerebrospinal fluid (CSF) around 118.00–132.00 (mM), and in urine around 110.00–250.00 (mM); while the concentrations of bicarbonate (HCO3-), the second most abundant anion in blood exists 22.00–29.00 (mM).
Chloride exists as the predominant extracellular anion. Chloride exists as a significant donor to the osmotic pressure gradient between the ICF and ECF and recreates an essential part of preserving proper hydration. Chloride functions to balance cations in the ECF, preserving the electrical neutrality of this fluid.
*ICF = intracellular fluid
ECF = extracellular fluid
