Answer:
A) Devonian
Explanation:
Fourth division of the Paleozoic era, the Devonian (or Devonian) comprises the period between 416 and 354 million years ago, succeeding the Silurian and preceding the Carboniferous.
Although in this period the terrestrial environment is increasingly conducive to life, the Devonian is still known as the "age of fish". During this period, the first vertebrae, sharks, lobed-fin fish, ray-finned fish and placodermos (group of fish with armor that took the top of the food chain) emerged. Some freshwater fish developed lungs, which gave them the ability to breathe out of the water - soon the first amphibians would originate from fish with lobed fins. On the continents, however, animal life was still marked by the presence of arthropods, such as arachnids and insects.
Caused by the body clearing out the chemicals that enter through the airways and lungs through tobacco use. Leads to a variety of other conditions like bronchitis, higher risk of bacterial and respiratory infections, emphysema, COPD, and lung cancer

proteins are one of the most abundant organic molecules in living systems and have the most diverse range of functions of all macro molecules. the functions of proteins are very diverse because there are 20 different chemically distinct amino acids that form long chains, and the amino acids can be in any order. For example, proteins can function as enzymes or hormones.
The correct answer is: B) "All roads lead to Rome"
Citric acid cycle also called tricarboxylic acid (TCA) cycle and Krebs cycle is a central process in cellular respiration. Citric acid cycle that connects carbohydrate, fat, and protein metabolism so “all the roads” from the different metabolic pathways come to this cycle.
Acetyl-CoA which is produced through the oxidation of pyruvate (pyruvate is a product of glycolysis) enters the cycle which then produces reduced electron carriers NADH, FAD2 and energy molecule ATP. These electron carriers will then pass their electrons into the electron transport chain and, through the process of oxidative phosphorylation, will produce more ATP.
