4 mps increase in 10 seconds = 2 mps increase in 5 seconds = .4meters/2sec
Molten material is allowed to solidify into the final shape.
Casting defects occur during solidification:
Gas porosity
Shrinkage
Two stages of solidification:
Nucleation
Growth
For evolution to occur:
There must be genetic variation in a population. This provides variation on which natural selection can act. Then natural selection can act by selecting those species which are better adapted to the environmental conditions. Over time those animals that are best suited to the environment only will survive and reproduce. Those organisms successful genes will be preserved and eventually the gene frequency in the population will change, changing the overall characteristics of a population. This is how evolution occurs.
Answer:
No
Explanation:
This species that we would be killing off is innocent and not volunteering for this.
