arteries and veins
Answer the following question given this paragraph: As the temperature of a perfect crystal increases, its particles start to vibrate slightly around their optimal positions, thus increasing the entropy of the system. The dependence of entropy on temperature varies by substance, so the only temperature at which all crystals have the same entropy is absolute zero. The standard entropy of a substance is a measure of its entropy at 25C and 1 atm of pressure. Like standard enthalpy of formation values, standard entropies are tabulated for a wide range of substances. However, unlike enthalpy of formation values, all standard entropy values are positive, because the absolute zero for entropy is the most ordered possible state. Additionally, this means that pure elements in their standard states do not have a standard entropy of zero. Q: The measure of a substances entropy at 25 degrees celsius is known as it's? Choices: - specific entropy - new entropy - limited entropy - standard entropy A:
standard entropy
Q: Answer the following question given this paragraph: Eukaryotic cells contain a nucleus and other organelles. They include the mitochondrion, endoplasmic reticulum, Golgi apparatus, vesicles, vacuoles, lysosomes, andin animal cellscentrioles. Each type of organelle has a special function. Q: Eukaryotic cells contain what type of structures that possess special functions? Choices: - cell membranes - fibers - chloroplasts - organelles A:
A: organelles
Question: Answer the following question given this paragraph: For example, remember that for the height gene in pea plants there are two possible factors. These factors are alleles. There is a dominant allele for tallness (T) and a recessive allele for shortness (t) . Q: What factors determine the effect of a gene? Choices: - metabolites - genomes - ribosomes - alleles A:
Answer: alleles

Answer the following question given this paragraph: In the health sciences, the concentration of a solution is typically expressed asparts per thousand (ppt), indicated as a proportion. For example, adrenalin, the hormone produced in high-stress situations, is available in a 1:1000 solution, or one gram of adrenalin per 1000 g of solution. The labels on bottles of commercial reagents often describe the contents in terms of mass percentage. Sulfuric acid, for example, is sold as a 95% aqueous solution, or 95 g of H2SO4 per 100 g of solution. Parts per million and parts per billion are used to describe concentrations of highly dilute solutions. These measurements correspond to milligrams and micrograms of solute per kilogram of solution, respectively. For dilute aqueous solutions, this is equal to milligrams and micrograms of solute per liter of solution (assuming a density of 1.0 g/mL). Q: What is the hormone produced in high-stress situations? Choices: - testosterone - thyroxine - somatostatin - adrenalin A:
**Answer**
adrenalin
