The true statements are:
1) Catabolism is the process in which complex substances are broken down, yielding a net output of energy.
Catabolism reactions break down macromolecules (lipids, proteins, nucleic acids and sugar) into smaller units that can be used for further reactions, for energy, for the synthesis of new polymer molecules or be simple waste products.
2) Metabolism is an integrated system in which many of the same reactions participate in degradative (catabolic) and biosynthetic (anabolic) pathways.
Metabolism combine all chemical reactions of an organism. Functions of metabolism include: providing energy form food molecules, synthesis of building blocks of the cell, elimination of the waste products.
3) Anabolism involves the synthesis of polymeric biomolecules and complex lipids from monomers such as fatty acids and nucleotides.
Anabolic reactions are opposite of those in catabolism: these reactions require energy (endergonic processes) for the synthesis of necessary molecules for the cells. That energy is the product of catabolic reactions.

According to the research, the primary purpose of membrane channels is to circulate ions, and of membrane pumps is to maintain differences in ionic concentration.
<h3>What are membrane channels and pumps?</h3>
They are pores in the cell membrane through which ions circulate for muscle contraction or membrane potential changes that may depend on a ligand or voltage, depending on whether their opening is determined by the binding of a ligand or by changes of voltage.
In this sense, membrane pumps is the mechanism of active ion transport, consuming energy across a membrane against an electromechanical gradient to maintain differences in ion concentration between the intracellular and extracellular space.
Therefore, we can conclude that according to the research, the primary purpose of membrane channels is to circulate ions, and of membrane pumps is to maintain differences in ionic concentration.

<h2><u>AnswEr :</u></h2>
The right answer is "Both insects and amphibians exhibit metamorphosis"
Have six legs :
- Amphibians are not six legged organisms rather they are four legged
Are both Vertebrates :
- Insects belong to the Phyla Arothropoda. Arthropods are invertebrates
- Amphibians belong to the Phyla Chordata. Chordates includes vertebrates
Go through Metamorphosis :
- Both insects and amphibians are found to exhibit metamorphosis. For instance, Butterfly incase of insects and Frogs incase of Amphibians
Are both Invertebrates :
- Insects are Invertebrates while Amphibians are Vertebrates
Look like their parents at birth :
- Insects don't resemble their parents at birth. As they grow into adults,they develop body patterns, structures similar to their parents
- Amphibians develop indirectly,from larvae. Indirect Development refers to the development where the embryo develops into a sexually - sterile organism after which it undergoes metamorphosis to become an adult.
