Oxygen or an oxidizing agent to receive electrons must be present for oxidation to occur in chemical reactions
Answer:
See the answer below
Explanation:
If the amount of light reaching a leaf and the water supply is adequate in the face of inadequate carbon dioxide, the <u>latter becomes a limiting reagent in the process of photosynthesis. </u>
The process of photosynthesis has two steps
1. The light reaction
2. The light-independent reaction/the Calvin cycle
<em>Carbon dioxide is only required in the second step which is the Calvin cycle. This means that the light reaction proceeds at a normal rate but the Calvin cycle is slowed due to inadequate carbon dioxide. Overall, the rate of photosynthesis becomes limited to the amount of carbon dioxide that is available in the leaf.</em>
Answer:
Homo species have differences in brachial index, face and teeth size as compared with australopithecines.
Explanation:
Australopithecines were found in pleistoocene era and adapted to the bipedal locomotion but shows differences in walking style as compared to early homo species. They have large brachial index. The postcanines were large but incisors and canines were small.
Early homo species were found around 2 million years ago. They shows bipedal locomotion with different walking styles. The brachial index of early homo species was small as compared with the australopithecines. The post canines were small but incisors and canines were large.
Answer:
The correct answer would be - nitrficiation, denitrification, nitrogen fixation, and decomposition.
Explanation:
Thiobacillus denitrification is a facultative, obligate chemolithoautotrophic anaerobic bacterium that is well known for its ability to couple the oxidation of inorganic sulfur-based compounds to denitrification.
The name of the bacterium is derived from its function or the metabolic ability as it performs denitrification on thio (sulfur) based inorganic compounds by the process of oxidation. This process helps in bioremediate groundwater by these processes of nitrogen fixation by oxidation of inorganic compounds of sulfur.
Thus, the correct answer is - nitrification, denitrification, nitrogen fixation, and decomposition.
Scientists believe the earth is approximately 4 1/2 billion years old
