Describe how BOTH Genetic Factors and Environmental Factors influence the growth of organisms, using the example of a Koi Fish living in a pond.
Identify environmental factors that impact growth (larger pond = more room to grow and larger fish, smaller pond = less room to grow and smaller fish, more fish = increased competition for resources and less growth, etc.)
Students planted 100 seeds in two different plots of land on the same day. At the end of the year, the first kind of plan grew to an average of 31 cm. The second kind of plan grew 121 cm. The difference in height of the plants was most likely influenced by what?
The genetic factors of the plants
Why is it important that the mouth and stomach are near the start of the digestive system?
The mouth and stomach account for most physical digestion. It's important for food to be broken into tiny pieces so nutrients can be exposed to the action of digestive enzymes.
