The correct answer is (c.) Scientists understood that species share a common ancestor. Scientists considered making a modern classification of an organism in order to organize in which these organisms belong to what ancestors. The Modern Taxonomy is the one responsible for classifying each organism.
The two enzymes that help in the generation of NADPH which is essential for fatty acid synthesis are the Glucose-6-phosphate-dehydrogenase(G6PDH) and the Malic enzyme.
NADPH is predominantly produced by the pentose phosphate pathway, either directly by the malic enzyme as it oxidized malate to pyruvate or indirectly through the glucose-6-phosphate dehydrogenase.
NADP+ is used to make NADPH. The pentose phosphate pathway, which is catalyzed in the first stage by glucose-6-phosphate dehydrogenase (G6PDH), is the main source of NADPH in mammals and other non-photosynthetic organisms.
From glucose, the pentose phosphate pathway also generates pentose, a crucial component of NAD(P)H.
However, the Entner-Doudoroff route is also used by some bacteria, and NADPH generation is unaffected.

Answer:
The term “epigenetics” was introduced in 1942 by embryologist Conrad Waddington, who, relating it to the 17th century concept of “epigenesis”, defined it as the complex of developmental processes between the genotype and phenotype.
Explanation:
Eutrophication occurs due to excessive use of these compounds, which can lead to having dead zones in bodies of water.
Dead zones refers to areas with decreased levels of oxygen in the bodies of water caused by eutrophication and other factors. These affect the marine life negatively as fishes are also dependent on oxygen.
Eutrophication is defined as the presence of excess minerals in the water, which causes dense growth of plants and leads to depletion of oxygen that make the animals in the water to die.
