Explain how natural selection can change behaviour in a population.
When human skeletal muscle relies more heavily on anaerobic respiration, which outcome is expected? A. A modest rapid ATP supply with lactate formation B. A greater ATP yield per glucose than complete aerobic oxidation C. Ethanol and oxygen as the main…
A vessel is used to grow microorganisms that produce a useful substance. State one physical or chemical condition to keep at an appropriate constant value to support production.
These tRNAs carry the amino acids shown. Which mRNA sequence encodes the tripeptide phenylalanine–glycine–lysine? Anticodon, written 3′→5′ | Amino acid AAG | Phenylalanine CCA | Glycine UUC | Lysine A. 5′–AAG CCA UUC–3′ B. 5′–TTC GGT AAG–3′ C. 5′–UUC GGU…
Neurons communicate with other neurons at chemical synapses. Explain the roles of neurotransmitters in this communication.
These constructed results compare corresponding gene sequences from two mammalian species. Greater divergence means more sequence differences. What can be deduced? A. The sampled autosomal sequences are less divergent than the Y-linked sequences B. The two…
Cut pear tissue normally darkens when oxygen is available because a polyphenol-oxidizing enzyme converts colourless compounds to pigments. A modified line shows no darkening under the same conditions. Suggest why the modified tissue does not darken.
A green leaf receives only a narrow band of blue light centred near 445 nm. Which plot could show the photosynthesis supported by the wavelengths actually supplied? A. Plot A B. Plot B C. Plot C D. Plot D
A microbial digester is supplied with a semi-liquid suspension of food-processing waste. Outline why this suspension is added.
A culture of microorganisms is grown in a fermentation vessel. Explain how conditions in the vessel can limit growth.
