When Charles Darwin stepped ashore on the Galapagos Islands in September 1835, it was the start of five weeks that would change the world of science, although he did not know it at the time. Among other finds, he observed and collected the variety of small birds that inhabited the islands, but he did not realize their significance, and failed to keep good records of his specimens and where they were collected.
Answer:
Although they are not closely related, as vertebrate animals, they share some characteristics and belong to the same Phylum.
Explanation:
Tigers and goldfish belong to different Classes. Tigers (<em>Panthera tigris</em>) belong to the Class Mammalia, while goldfish (<em>Carassius auratus</em>) belong to the Class Actinopterygii. However, they both belong to the Phylum Chordata.
Chordates share particular characteristics, such as a dorsal neural tube, a notochord, a bilateral symmetry, circulatory system, amongst other features. They are divided into different groups of vertebrates as well: mammals, birds, amphibians, reptiles, and fish. And, according to evolutionionary studies, over 300 million years ago, the first vertebrates that lived on land (amphibians) evolved from a lobe-finned fish species, which eventually led to the evolution of mammals that adapted to terrestrial environments.
Therefore, even though goldfish and tigers may seem completely different, they share similar characteristics. Plus, they are vertebrates that belong to the same phylum.

Answer:
b. Mitochondrial respiration
Explanation:
Mitochondrial respiration of plants involves the participation of two major electron transport routes:
1. Cytochrome c oxidase route: cyanide sensitive and coupled to three energy conservation sites.
2. Cyanide-insensitive alternative route: involves alternative oxidase (AOX), branches off the cytochrome oxidase route into the ubiquinone pool, with no energy conservation thereafter as AOX is able to directly oxidize ubiquinol and reduce oxygen to water.
Regardless of the route followed, mitochondrial breathing is a long and complex process. However, it is through this breath that at a given moment electrons are passed to oxygen through a carrier channel in the inner mitochondrial membrane. This happens when cytochromes to and some molecules that have a heme group (with an iron atom) and are linked to a transmembrane protein that connects the matrix to the mitochondrial intermembrane space and have two copper atoms that allow the transport of electrons to the final acceptor, oxygen (O2).
