Yes when fossil fuels are burned they release the carbon dioxide locked inside of them
that is why fossil fuels are a big source of global warming and we will eventually run out of fossil fuels
Answer:
A. NADH and FADH2 both donate electrons at the same location.
Explanation:
In the respiratory chain, four large protein complexes inserted into the mitochondrial inner membrane transport NADH and FADH₂ electrons (formed in glycolysis and the Krebs cycle) to oxygen gas, reducing them to NAD⁺ and FAD, respectively.
These electrons have great affinity for oxygen gas and, when combined with it, reduce it to water molecules at the end of the reaction.
Oxygen gas effectively participates in cellular respiration at this stage, so its absence would imply interruption of the process.
NADH and FADH₂ electrons, when attracted to oxygen, travel a path through protein complexes, releasing energy in this process.
The energy released by the NADH and FADH₂ electrons in the respiratory chain in theory yields <u>34</u> <u>ATP</u>, however, under normal conditions an average of 26 ATP molecules is formed.
If we consider that these 26 molecules are added to the two ATP formed in glycolysis and two ATP formed in the Krebs cycle, it can be said that cellular respiration reaches a maximum yield of 30 ATP per glucose molecule, although theoretically this number was 38 ATP per glucose molecule.

Answer:
C. Diploid condition
Explanation:
A Karyotype is the pictorial display that shows chromosome arrangement and number in a cell. The Karyotype shows any abnormalities in the nuclear material (chromosomes). In a carrot plant that was cloned from carrot root, the clones should possess the same features as the original plant.
A Karyotype of both plants i.e. clone and the original plant should show that their cells have a diploid number of chromosomes i.e. Two sets of chromosomes. Since a carrot plant is a diploid organism.
