The correct answer is A, D, E.
A. Cambrian.
D. Permian.
E. Silurian.
Triassic period was termed as the period for the mesozoic era. This time period followed extinction of great mass which founded at the end of period of permian.
It is during the period of triassic when first mammal and dinosaur appeared.
During late permian, plants like horsetails and mosses were extinct.
Those plants which evolved in on the of triassic were cydophytes and confers.
the heart has valves in place to prevent the backflow of blood.
Answer:
1) The correct answer would be A. it transfers carbon to the atmosphere as carbon dioxide.
Cellular respiration refers to the set of biochemical reactions take place in a cell in order to convert the energy of glucose into adenosine triphosphate (ATP).
The carbon dioxide is released as the byproduct of the process.
C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + ATP
2) The correct answer would be D. fermentation can occur without oxygen.
Fermentation is the process which occurs in oxygen is either absent or present in very less amount.
Thus, it enables the cell to survive when oxygen is not available.
For example, in humans, the muscle cells switch to lactic acid fermentation when oxygen supply is decreased during intense exercise.
It produces very less amount of ATP as compared to the aerobic respiration.
