Select the largest, most inclusive biological level from the following choices. A. Molecule B. Tissue C. Organ D. Cell User: Nucleic acids are composed of monomers called A. amino acids. B. ribose. C. nucleotides. D. base pairs.
Weegy: The answer is, Nucleotides. Nucleic acids are made of smaller molecules known as "nucleotides". User: Which of the following is true about bases? A. They tend to decrease the pH of a solution. B. They help to build up cells. C. They have a sharp or sour taste. D. They release hydroxide ions in solution. User: Which of the following is true about bases? A. They tend to decrease the pH of a solution. B. They help to build up cells. C. They have a sharp or sour taste. D. They release hydroxide ions in solution. User: The following atoms are all variations of the element carbon: 12C, 13C, and 14C due to differing numbers of neutrons. What are these variations called? A. Polymers B. Isomers C. Isotopes D. Molecules User: The Calvin cycle of photosynthesis begins when A. electrons leave a photosystem. B. light becomes available. C. the reduction of carbon dioxide occurs. D. carbon dioxide is attached to RuBP. Weegy: The Calvin cycle of photosynthesis begins when: B. light becomes available. The Calvin Cycle of photosynthesis begins when light independent reactions power the energy requiring second stage of photosynthesis. [ The light independent reaction that make up this stage convert carbon dioxide to glucose and other carbohydrates. The Calvin cycle is a cyclic pathway, in which the product of the last reaction is the starting material of the first reaction. ] (More)

Weegy: Which one of the following reactions occurs in the cristae of the mitochondria? C. The electron transport chain User: what occurs in the cristae of the mitochondria? Weegy: what occurs in the cristae of the mitochondria? The mitochondrion is referred to as the ‘power house’ of the cell, because it is responsible for the synthesis of the majority of ATP under aerobic conditions. [ The inner membrane of the mitochondrion contains the components of the electron transport chain. Oxidation/reduction reactions along the components of the electron transport chain generate a proton gradient that is used by ATP synthase to phosphorylate ADP, thereby producing ATP. To increase the capacity of the mitochondrion to synthesize ATP, the inner membrane is folded to form cristae. These folds allow a much greater amount of electron transport chain enzymes and ATP synthase to be packed into the mitochondrion Source(s): ] User: Which of these is the smallest structure? A. Protein B. Polypeptide C. Dipeptide D. Amino acid Weegy: Which of these is the smallest structure? D. Amino acid Amino acid. This is because dipeptides and polypeptides are chains of amino acids. [ Amino acids are the monomers. ] User: When a scientific experiment is carried out in a controlled setting, all variables are kept the same except for the _______ variable. A. observational B. control C. experimental D. environmental Weegy: The answer is C. experimental. (More)
