When we say "survival of fittest" does it mean that
(a) Those which are fit only survive or
(b) Those that survive called fit.

Endoparasites are found inside the host body. Mention the special structures, possessed by these and which enables them to survive in those conditions.

Write whether the following statements are true or false with proper justification for your answer: The theory of natural selection which mention 'Survival of fittest' is given by Lamarck.

Based on is observations of plants and animals, Darwin suggested that only the fittest organisms survive.

Cellular respiration is the oxidation of foodstuffs for the production of energy. During aerobic respiration, complete oxidation of glucose takes place.Contradictor to this, glucose is incompletely oxidized durin anaerobic respiration . Many microbesare capacble of surviving anaerobically in environments that lack oxygen. Anaerobic respiration occurs via two steps,namely glycolysis and fermentation. The pyruvic acid formed during glycolysis is converted to organic acids or alcohols during anaerobic process. higher animals and plants, or seeds submerged in soil under water are capable ofperforming anaerobic respiration, when the oxygen levels are depleted .Even body cells like erythrocytes and mscle cells perform anaerobic respiration. How does anaerobic respiration occur in yeast?

Considering that only glycolysis is generating energy currency , how many ATP would be formed during anaerobic respiration?
