Catabolism + anabolism = metabolism
➡️Metabolism is a biochemical process that allows an organism to live, grow, reproduce, heal, and adapt to its environment.✔️
➡️Anabolism and catabolism are two metabolic processes, or phases.✔️
➡️Anabolism refers to the process which builds molecules the body needs; it usually requires energy for completion.✔️
➡️Catabolism refers to the process that breaks down complex molecules into smaller molecules; it usually releases energy for the organism to use.✔️
Hope it clear your doubts regarding the topic! :)
Explanation:
Echinoderms get their food and oxygen for energy. They use tube feet to obtain from the water. The tiny tube feet are involved in passing collected food towards the central mouth.These animals are detritivores performing similar functions to earthworms on the land in recycling nutrients.
Consumers because scavengers hunt for food b
D. is the correct answer. It uses neurons to signal.
The electrons in the outermost shell of the covalent compounds are shared by nearby atoms. As there are no free electrons for conducting electricity, the covalent compounds are perfect insulators at absolute zero. As the temperature increases, some electrons move from valence band to conduction band. This gives rise to conductivity. But as the numbers of charge carriers are very low, covalent compounds are poor conductors. On the other hand metals are good conductors cause of their bonding. Metallic bonding consists of a sea of electrons rather than discreet bonds. The free electrons are able to move freely. Since electricity and heat need electrons to move, the bonding promotes conductivity.
