QUESTION 2 (A) The pentose phosphate pathway is comprised of two phases. Why are both phases necessary for the survival of the cell? (2pts) (B) In the non-oxidative phase of the pentose phosphate pathway ribose 5-phosphate is converted to fructose 6-phosphate. Why does this pathway require so many enzymatic steps? What benefit does each step provide? (4 pts) (C) Many cancer drugs are effective because they reduce cell proliferation by reducing the amount of base material needed for cell division...
Explain the phenomenon of nondisjunction that may cure during gamete meiosis, & describe some of the consequences that can arise if nondisjunction ocures for sex and non-sex chromosomes.
Describe the price elasticity of supply or demand of laptops at Walmart. Explain how two non price factors that impact the demand of the laptops. Explain how two non price factors impact the supply of laptops. Define the industry and the market equilibrium associated with laptops. Predict the effect of changes in supply and demand on the market equilibrium.
help with question 3 & 4 please 3. The concept of Hardy-Weinberg equilibrium specifies five conditions under which Hardy Weinberg equilibrium will be violated and evolution will occur. Describe two conditions which generate random changes to allele frequency in a population. Describe one condition which generates non-random changes (adaptations) to allele frequency in a population. (6pts) 4. In a population of fish, short scales (s) is recessive to the wild-type condition of long scales (S). You isolate a population of...

Of the two embryos, which one would you predict would have a poorly developed placenta? . 3.Describe the process of calcium release as a result of an action potential transfer from the neuromuscular junction.
Effect Malnutrition During Pregnancy May occur as a result of an undernourished mother during pregnancy who gains too little weight. The source of all nutrition for a developing fetus, malnourishment in a pregnant woman may actually lead to its increased sire at the expense of increased fetal size. Malnutrition during pregnancy may result in decreased vasculature of this organ that holds the developing fetus. Uterus Placenta Low birth weight Pregnant women have nutrient needs that differ from non-pregnant women. Some...
A television commercial touts the wonders of a new non-prescription diet pill said to control weight gain by binding fat and keeping it from being digested and absorbed. Assuming the pill does what it claims to do, list and describe the undesirable side effects that may occur when taking this pill.
