Answer:

a) Teeth arose from the rough scales of ancestral sharks.

b) Skeletal developments leading to the amphibian movement onto land probably evolved from lobe-finned fishes.

d) The anterior gill arch formed the basis for the evolution of the vertebrate jaw.

Explanation:

The animals we know today have physical characteristics that are evolutionary adaptations of characteristics of their ancestors, which have undergone a series of evolutions and modifications over the years giving rise to new species that have resulted in the species we know today. This process of evolutions and adaptations also happened with the ancestral species of fish, which allowed that today, they had characteristics such as teeth and jaws. Many of these evolutions occurred even in different species, such as the evolution that allowed the amphibians to have a skeleton, which evolved from the spine fins of fish.

Correct answer: C). Oxidative phosphorylation

Oxidative phosphorylation gives a basic unit of energy for all the metabolic processes called as ATP, it is a highly efficient metabolic process which is known to produce a large amount of ATP.

During the process of oxidative phosphorylation, electrons are exchanged between the molecules, that creates a chemical gradient, which is required for the production of ATP. It is known to produce more ATP called the energy currency of cell that any other cellular respiration. It produces 90% of the total ATP synthesized in the cell.

What is a prokaryote, and when did prokaryotes arise?
RideAnS [48]
<span>A prokaryote is a unicellular organism that belongs to either the domain Bacteria or the domain Archaea. Therefore, unlike a eukaryote, the prokaryote lacks in a nucleus and other organelles. The first organisms that appeared about 3.5 billions years ago were prokaryotes. They developed primitive forms of photosynthesis without oxygen as a waste. The first photosynthesizing prokaryotes appeared about 2.7 billion years ago which led to the changes in Earth atmosphere and consequently organisms dependant on oxygen could arise.</span>
