Nerve, muscle, blood, and epithelial cells share DNA but have different shapes and proteins.
Learning target
Build an initial model and explanation for: How can cells with the same genome become structurally and functionally different?
Evidence task
Record observations, questions, an initial model, and one claim that could be tested. Use these concepts where relevant: differentiation; gene expression; tissue; organ; organ system.
Show units, setup, calculation or graph reasoning, then write what the quantitative evidence can and cannot establish about: How can cells with the same genome become structurally and functionally different?
Image-based cell specialization classification and systems model.
Safety boundary
Use the course safety charter. If supervision, facilities, materials, or conditions are not appropriate, use the supplied-data/simulation alternative rather than improvising hazardous procedures.
Evidence task
Record variables or design constraints, procedure/model, observations/data, and one revision you would make after reviewing the evidence.
Answer the essential question: How can cells with the same genome become structurally and functionally different?
Mastery evidence
Submit a claim, at least two specific pieces of evidence, reasoning that connects them, one limitation/counterclaim, and a correction note for any essential concept below 80%.
Portfolio
Select one artifact from this week and explain why it is trustworthy evidence of growth.
