Answer & explanation:
Fungi have long been regarded as organisms that were part of the <em>Plantae</em> kingdom (plants), mainly because they have cell walls in their cells, reproduce by spores, and the fact that some of them are sessile (attached to the ground).
However, fungi are no longer considered as plants because they do not have chlorophyll or specialized cells, such as chloroplasts and vacuoles. In addition, fungi have heterotrophic nutrition (plants are autotrophic), needing to absorb organic substances to survive.
Nowadays, fungi are studied in isolation and are inserted in their own kingdom, the <em>Fungi</em> kingdom.
Explanation:
amphibians have smooth, sticky wet and highly porous skin to perform various functions.
reptiles have a dry, hard and scaly skin, which guards them in harsh conditions.
amphibians lay their eggs in water and cover them with gel.
reptiles lay their eggs on land and have a hard protective shell.
Answer:
The electron transport chain
Explanation:
During the citric cycle in the matrix of the mitochondria, the NAD+ and FAD+ the metabolic cycle are reduced to NADH and FADH₂ through accepting electrons. The energy harnessed from the metabolic cycle is used to develop a proton motive force across the mitochondrion intermembrane. This potential energy is harnesses by ATP synthase to create ATPs. As the H+ ions drain back into the matrix of the mitochondria, they are used to reduce oxygen to water. In this redox reaction, the FADH₂ and NADH donate their electrons and are recycled back to the citric cycle in their oxidized form.
