Answer:
any movement of genes from one population to another
Mature elodea leaves has the average of 35 chloroplasts in each cell while young elodea leaf has the average of 25 chloroplasts in each cell.
Elodea cell is a plant cell that has many organelles such as a nucleus, many chloroplasts, a hard cell wall, a thin and transparent cell membrane, cytoplasm, and a central vacuole. The number of chloroplasts present in each elodea cell is determined by some factors such as the age of the leaves and the presence of any plant growth stimulants. Mature elodea leaves have the tendency to have more chloroplasts than young elodea leaves. Mature elodea leaves has the average of 35 chloroplasts in each cell while young elodea leaf has the average of 25 chloroplasts in each cell.
Three cases happen when a light wave strikes an object. Light waves can either be: absorbed, reflected or refracted. The differences are as follows:
a. Absorption - light stops at the object causing it to appear dark or opaque.
b. Reflection - this could happen either in a smooth or rough surface. On a smooth surface, for example mirror or glass, light bounces off the surface at angle equal to the incoming light wave. On a rough surface e.g. earth, light bounces at many angles because the surface is uneven.
c. Refraction - light goes through the object and bends at an angle. Typical thing you see when diamond or water is struck by light.
1. They observe how the ocean, atmosphere, and climate affect one another
2. Plan experiments, write reports and scientific papers
3. Troubleshoot risks to coasts from storms and tidalwaves
