Questions to ask about science, nature and school subjects
You find out whether you understand mitosis when you have to explain it. These sets are for students, tutors and study groups, covering biology, the periodic table, economics, sociology, statistics, Greek myth and history. A few are conversations about nature, the sea, plants and the environment.
A few to start with
What criticism did he face from inside the movement after 1965?
The work moved north into housing and jobs, where there was no single law to overturn, and younger activists calling for Black Power found his methods slow and too willing to accommodate. Skip this and his last three years look like a decline rather than an argument he was losing ground in.
What are the phases in order, and what single event defines each one?
Reciting names is not the skill being tested; matching one defining event to each is. Chromosomes condensing, the nuclear envelope breaking down, alignment at the equator, sister chromatids separating, and nuclei re-forming give you five checkpoints you can identify from a diagram.
How was the sinking reported at the time, and how accurate was that reporting?
Early reports were wrong in significant ways, including about whether the ship had sunk and how many were saved, because information came in fragments over wireless. It is a useful case study in how a story stabilises days after the event.
Why do endocrine problems often present as vague, whole-body symptoms?
Because hormones reach nearly every tissue, so the same underlying problem shows up as fatigue, weight change, temperature intolerance, and mood change together. This is also why these conditions are diagnosed by blood tests rather than by symptoms alone.
Have you ever been frightened outdoors?
Weather that turned, a wrong turn after dark, water moving faster than it looked. These stories are more revealing than any account of a pleasant walk, and they tell you how much risk this person is willing to be near.
How does one set of DNA instructions produce hundreds of different cell types?
This is the question that separates memorizing organelles from understanding cells. The answer is about which genes are switched on rather than which genes are present, and the fact that every cell type shares one genome is the whole point.
