What is the relationship between tumor size and resistance to invasion?
What is the relationship between tumor size and resistance to invasion?
- Tumors with larger size are more resistant to invasion (correct)
- Tumor size does not affect resistance to invasion
- Tumor size and resistance to invasion are unrelated
- Tumors with smaller size are more resistant to invasion
Why are small, cheater-only tumors more able to facilitate the successful proliferation of metastasis-promoting lineages?
Why are small, cheater-only tumors more able to facilitate the successful proliferation of metastasis-promoting lineages?
- They have better invasion conditions
- They have larger sizes
- They experience fewer mutations (correct)
- They accumulate more mutations
How does increasing niche construction specificity affect the stability of a producer-only tumor?

- It increases stability (correct)
- It has no impact on stability
- It decreases stability
- It makes secondary producers invade successfully
