Answer:
The stages of cellular respiration are - glycolysis, pyruvate oxidation, the citric acid or Krebs cycle, and oxidative phosphorylation.
The products at each step are -
Glycolysis - 2 ATP, 2 NADH, and 2 pyruvate molecules
pyruvate oxidation - acetyl CoA and NADH
Krebs cycle - carbon dioxide, NADH, FADH2, and ATP or GTP.
oxidative phosphorylation - H2O, ATP, NAD+, and FAD+.
Reactants are used at each step -
Glycolysis - glucose
pyruvate oxidation - Pyruvate and CoA
Krebs cycle - Pyruvate
oxidative phosphorylation - the electron donors such as NADH and FADH2
The end product of respiration:
carbon dioxide and water are final products
Answer:
The effect of biogeochemical cycles is the recycling of matter in the biosphere. In biogeochemical cycle, the matter is moved in a pathway.

Answer:
The correct option is B
Explanation:
The <u>biomolecule used in comparing lizards A and B is the mitochondrial DNA while that used to compare the same lizard B to another lizard C is the ribosomal RNA (rRNA)</u>. <u>They should have compared the same biomolecules throughout</u> by extracting the mitochondrial DNA of the three lizards and then proceed to sequence the whole genome of the lizards. After which they can now do a Global alignment (comparison) of the three sequences together. This procedure would have given them a more accurate information on there identity and similarity.
The correct answer is predatory birds.
The flowing of toxic chemicals and heavy metals into the water body when the agricultural, industrial, and human wastes run off or are discharged intentionally into the water body is known as biomagnification. These pollutants result in genetic mutations, disease, reproductive difficulties, birth defects, death, and behavioral modifications in various marine species.
However, the extremity of the destruction varies significantly among the species. In various circumstances, the animals close to the top of the food chain are most influenced by the procedure of biomagnification.
Several of the harmful toxins get settle at the lower level in a water body and are then consumed by the species, which feed or live on the bottom dwellers. As these constituents are not digested, they gathered inside the bodies of the species, which consumes them.
It signifies that the higher level predators, like fish, birds, or marine mammals accumulate more harmful concentrations of toxic substances in comparison to the animals lower on the food chain. Thus, in the given case, the more concentrated amount of toxins would be found in the predatory birds.
