The cenozoic era follows the end of the period.
1.triassic
2.jurassic
3.permian
4.cretaceous

Option (D)

Explanation:

The Cenozoic era starts after the end of the Cretaceous. It is marked by the global mass extinction event known as the Cretaceous-Tertiary (K-T) boundary. The Cenozoic era started from about 65 million years back to the recent.

The new species started to evolve from the start of this era and there were abundant land animals during this era, and so this era is often regarded as the age of mammals. This is the most recent era in the geological time scale and is marked by the diverse group of organisms that has appeared after a long evolutionary process.

The Cenozoic era is again divided into three parts-

1) Tertiary- It is divided into (a) Palaeogene, (b) Eocene, and (c) Oligocene

2) Neogene- It is divided into (a) Miocene and (b) Pliocene

3) Quarternary- It is divided into (a) Pleistocene and (b) Holocene

Thus, the correct answer is option (D).

both anaerobic and aerobic respiration use glucose (or other carbohydrates), proteins and lipids to produce atp and nadh. cell uses those energy molecules, obtained from food and   breaks them down during the chemical reactions of respiration. in anaerobic respiration, nadh is regenerated to nad+ by enzymes lactate dehydrogenase (lactate is produced, e.g. in muscle cells) or by alcohol dehydrogenase where ethanol is produced (alcohol fermentation), while in aerobic respiration, electrons from nadh are deposited in the mitochondria to regenerate nad+ (electron transport chain. anaerobic respiration produces 2 atp per molecule of glucose compared to aerobic respiration where about 38 atp molecules are produced.

meteorologists would compare a new weather map with one 24 h old to see how fast a front is moving.
