Which one of the following terms characterizes the interaction between the herpes simplex virus and a human?
Detailed Explanation:
Parasitism is a biological interaction where the parasite benefits while the host is harmed.
The herpes simplex virus infects human cells, uses the host's cellular machinery to replicate, damages cells, and causes diseases like cold sores or genital herpes, clearly harming the host while benefiting itself — a classic example of parasitism.
In lichen, a chlorophyll-containing partner, _______ live together.
Detailed Explanation:
Lichens are classic examples of symbiotic associations between algae (or cyanobacteria) and fungi.
The algal partner (phycobiont) contains chlorophyll and performs photosynthesis, providing organic nutrients, while the fungal partner (mycobiont) provides protection, water, and minerals.
Therefore, Option 1 (algae and a fungus) is correct.
Most of the enzymes are
Detailed Explanation:
Enzymes are biological catalysts that accelerate chemical reactions in living organisms, and the vast majority are proteins. They possess specific three-dimensional structures formed by amino acid chains, enabling them to bind substrates and facilitate reactions.
While a few enzymes are ribozymes (RNA-based), over 99% of all known enzymes are proteinaceous. Lipids, acids, and alkalis serve other biological functions but do not constitute enzyme structure.
Therefore, proteins form the structural basis of most enzymes, making Option 4 the correct answer.
