protein, cannot consume milk or products made from milk. Given this information, which of the following statements is true? A. The protein that causes a true milk allergy is lactose. B. All people who are lactose intolerant are also allergic to milk. C. Yogurt contains live and active cultures of Lactobacillus acidophilus bacteria and therefore prevents an allergic response in people with a true milk allergy. D. Lactose is a carbohydrate, not a protein and is therefore not the cause of tru...

This practice is about ____________________________ knowledge. Bringing together different disciplines. - Answer connecting Scale: draw and label intersecting diagram and use one of his examples: - Answer complexity, timespan, + size -very simple to very complex -ex: Dna in relation to Ecosystem (see notes for diagram!) Domains outside of biology - Answer Thermodynamics (Physics), Biochemistry, and Chemistry -using bio, chem, and math Thermodynamics (Physics) Example: - Answer all energ...

2 organelles that contain their own DNA separate from the chromosome - Answer Mitochondria and chloroplast What domains fall under prokaryotic cells? - Answer Bacteria and archaea What are the basic features of all cells? - Answer Membrane, cytoplasm, chromosomes, ribosomes This organelle synthesizes lipids, metabolizes carbohydrates, detoxifies poison, and stores calcium - Answer Smooth ER This cell is characterized by having DNA in a nucleus that is bound by a nuclear envelope and membra...

Water characteristics - Answer polar, cohesion (hold together), adhesion (hold to another substance), surface tension, specific heat, heat of vaporization Surface Tension - Answer A measure of how difficult it is to stretch or break the surface of a liquid Specific Heat - Answer amount of heat absorbed or lost to change temperature by 1C Heat of Vaporization - Answer the quantity of heat required to convert 1 from liquid to gas Water polarity - Answer uneven sharing of electrons that produc...

[D] interactions between amino acids present in the polypeptide. - Answer [2] The tertiary structure and function of a polypeptide is principally determined by the: ----------------------------------------------- [A] length of the polypeptide. [B] number of nucleotides present in the polypeptide. [C] repeated units of glycerol making up the polypeptide. [D] interactions between amino acids present in the polypeptide. [E] number of introns within the polypeptide. [B] Two - Answer [3] In a...

Humans produce sweat as a cooling mechanism to maintain a stable internal temperature. Which of the following best explains how the properties of water contribute to this physiological process? - Answer The high heat of vaporization of water allows the body to remove excess heat through a phase change of water from liquid to gas A student placed a semipermeable membrane inside a U-shaped channel with two chambers, as shown. The membrane permits the movement of water but not salt. The s...
