This independent study page provides practice for Castilla y León PAU Biology. Its editorial learning areas include Biochemistry; Cell structure, membranes and division; Genetics, inheritance and molecular information; Metabolism; Biological inquiry and interpretation of evidence; Microbiology Immunology; Biotechnology. The questions develop subject knowledge and application through worked reasoning, distinctions between competing answers, and practical scenarios. Study the relevant guide before attempting a mixed set, then explain the evidence or calculation that supports each answer. Topics on this exam: Biochemistry, Cell structure, membranes and division, Genetics, inheritance and molecular information, Metabolism, Biological inquiry and interpretation of evidence, Microbiology Immunology, and Biotechnology. The Castilla y León PAU Biology case studies are 4 cases and about 1,065 words.
1Potato-cell mass change and a controlled concentration comparison
A class analyzes a supplied dataset from equal-sized potato cylinders placed in several labeled solutions. The cylinders began with the same average mass, and the observation interval, temperature and blotting convention were matched.
262 words, about 1 min2A pea-plant cross and the meaning of an expected ratio
A hypothetical pea trait is controlled by a single autosomal locus with alleles P and p. Complete dominance is explicitly assumed: PP and Pp plants have purple flowers, while pp plants have white flowers.
264 words, about 1 min3Enzyme-rate models without assuming a binding location
A class receives fitted rate models for a harmless hypothetical enzyme system; no experiment or chemical treatment is being prescribed. Both curves follow the simple Michaelis-Menten form v = Vmax times S divided by Km plus S over the stated measurement range.
