Answer:
Cellular respiration continues in the mitochondria of the cell with the Krebs cycle and the electron transport chain.
Explanation:
The Krebs cycle is an important part of the cellular respiration process where —from energetic substrate such as carbohydrates, lipids and eventually proteins— Acetyl-CoA is obtained, whose oxidation produces energy in the form of ATP.
Both cellular respiration and Krebs cycle reactions occur in the mitochondria of the cells of aerobic organisms and, in conjunction with the electron transport chain, have a yield of 24 molecules of ATP for every molecule of glucose entering the system.
Cellular respiration continues in the mitochondria of the cell with the Krebs Cycle and the Electron Transport Chain. The Krebs Cycle metabolizes pyruvate molecules from glycolysis to produce ATP, NADH, and FADH2. These molecules are then used in the Electron Transport Chain, which uses oxygen as the final electron acceptor to create more ATP.
The blank in your statement 'Cellular respiration continues in the mitochondria of the cell with the _____________ cycle and the electron transport chain' is filled by the Krebs Cycle, also known as the Citric Acid Cycle or the Tricarboxylic Acid (TCA) Cycle. During this cycle, pyruvate molecules generated during glycolysis are metabolized by enzymes in the mitochondria, leading to the production of ATP, NADH, and FADH2. These energy-rich molecules are then utilized in the Electron Transport Chain (ETC).
The ETC is the final stage of aerobic respiration that uses free oxygen as the final electron acceptor for the electrons removed during the Krebs cycle. This results in the generation of water. In addition, electrons are rapidly passed from one component of the ETC to the next in a series of redox reactions that generate an electrochemical gradient. This gradient is key for the production of ATP through oxidative phosphorylation.

Explanation:
B.Linnaeus’s work accounted for evolution.
C.Linnaeus did not use structural comparisons.
Answer:
On Edge2020 there are 4 answers, the last one (D) is: Linnaeus primarily used physical characteristics.
Explanation:
Out of the 3 answers you provided, A would be the most valid, (although somewhat wrong). If this was from the Edge Assignment then the correct answer is D.
Chemical digestion involves the breaking down of food with enzymes;
mechanical digestion is breaking down food by chewing and tearing with teeth.
Chemical digestion is the breakdown of fats; mechanical digestion is the breakdown of proteins.
Chemical digestion is done only by the major structures of the digestive system; mechanical digestion is done by the accessory structures of the digestive system.
