Answer:
Human activities are causing imbalance of carbon based molecule.
Explanation:
It is the human intervention in the most unavoidable way that is affecting the environmental cycle and one of these cycle is the carbon cycle. Human activities such as burning of fossil fuels, excessive cutting of trees, rising green house effect, use of CFCs etc is hindering the environment process and hence causing imbalance on the earth.
Answer:
Horizontal
Explanation:
Horizontal gene transfer may be defined as the transfer of the genetic material from the parents to their offspring. Three main methods of horizontal gene transfer are conjugation, transformation and transduction.
The transfer of plasmid among the members of bacterial community mainly occur by the horizontal gene transfer. This transfer of genetic material allows the bacteria to withstand at extreme conditions, confer antiobiotic resistance and increase their chance of survival in the environment.
Thus, the answer is horizontal gene transfer.
S waves can only move along the surface of the planet like ripples on water.
Answer: A. Pyruvic acid, the product of glycolysis, is the starting block for both the Krebs cycle and fermentation.
Explanation: Glycolysis is a metabolic pathway that oxidize glucose producing pyruvic acid and few ATP molecules. If the cellular microenvironment is aerobic, pyruvic acid is converted in Acetyl coA and enters into Krebs cycle and later into electron transport chain, which produce large amounts of ATP. If the cellular microenvironment is anaerobic, fermentation occurs and pyruvic acid is converted in lactic acid, ethanol, etc, producing only few ATP.
