Human Olfactory Data Explorer

Human Olfactory Data Explorer is a biology topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Human Olfactory Data Explorer rather than just read about it. In short: The Human Olfactory Data Explorer (HORDE) is a database of human olfactory receptors. The database provides information of the human olfactory receptor families, as well for dogs, platypuses, opossums and chimpanzees.

Key takeaways

Human Olfactory Data Explorer belongs to biology; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Human Olfactory Data Explorer to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Human Olfactory Data Explorer from memory before moving on to harder problems.

Worked examples

Example 1 — a first encounter with Human Olfactory Data Explorer

Start with the simplest possible case. Write down what Human Olfactory Data Explorer claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In biology, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Human Olfactory Data Explorer before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Human Olfactory Data Explorer ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Human Olfactory Data Explorer

In research: Human Olfactory Data Explorer appears in biology research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Human Olfactory Data Explorer in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Human Olfactory Data Explorer is common in secondary-school and first-year university syllabi. It links to neighbouring topics Biological databases, so understanding it makes those chapters shorter.
In everyday life: Look for Human Olfactory Data Explorer outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
