This figure illustrates 3 hypotheses of how a cancer stem cell may arise: (1) A stem cell undergoes a mutation, (2) A progenitor cell undergoes two or more mutations, or (3) A fully differentiated cell undergoes several mutations that drive it back to a stem-like state.
Answer:
Molecules stop moving at freezing point. Helium has the lowest boiling point. The molecules move very quickly at boiling point.
Explanation:
Heating up- molecules move faster. Cooling down- molecules move slower
Acceleration (a) is the change in velocity (Δv) over the change in time (Δt), represented by the equation a = Δv/Δt. This allows you to measure how fast velocity changes in meters per second squared (m/s^2). Acceleration is also a vector quantity, so it includes both magnitude and direction.

Answer:
The correct answer is C) There is a larger variety of MHC proteins that can be expressed on the cell surfaces of their immune cells, providing a wider opportunity to recognize and attack pathogens.
Explanation:
Match each biodiversity restoration method to its description we have:
- reforestation: using plants to absorb harmful compounds
- biological augmentation: using plants to control a native plant population
- bioremediation:using plants to increase biodiversity and food resources
<h3>What are ecological restoration techniques?</h3>
Some examples of induced ecological restoration methodologies are the conduction of natural regeneration, nucleation techniques, enrichment or diversity planting, among others.
In this case, the ecological restoration techniques are:
- reforestation: using plants to absorb harmful compounds
- biological augmentation: using plants to control a native plant population
- bioremediation: using plants to increase biodiversity and food resources
