The answer is true, the first option
The anaerobic cellular systems or anaerobic respiration use fermentation because the anaerobic cellular systems oxygen is absent. Fermentation takes place in the absence or in the partial pressure of oxygen to produce alcohol or lactic acid. This is the way of production of ATP which is need for various cellular processes.
If fermentation was not there, then the anaerobic cellular systems could not produce energy and the cellular processes could not occur. In the absence of fermentation, no ATP would be produced and the cells would gradually die.
Answer:
Quaternary
Explanation:
The Quaternary period which began around 2.6 million years ago or 2,588,00 years ago is known as the Age of humans.
During this period, the tectonic planets are in a place they are today but the climate was cold and ice glaciers started retreating.
During this period, the evolution of mammals reached on peak and the hominid lines began to evolve as the fossils of the first human belonged to this period. Homo erectus for the first time appeared at the beginning of this period and then evolved later into modern humans after they travelled to Europe and Asia.
Thus, Quaternary is the correct answer.
Answer:
Plants grow well at optimum temperature. When the temperature goes too high, plants growth is negatively effected. During high temperature of the surrounding, photosynthesis reaction slow down while respiration rate increases. Due to increase in respiration rate, the growth and development of plants is stopped because more food is utilized for energy production as compared to food production.
