The cytoplasmic streaming can be defined as the movement of the cytoplasm inside the cell. This movement of the cytoplasm helps in the delivery of the metabolites, organelles, and nutrients to all the parts of a cell. The cytoplasmic streaming, which is also known as cyclosis, occurs at the same rate throughout the cell and moves in the direction of the light.
Hence, the answer is 'moves at same rate and towards light'.
Answer:
When cancer spreads, it keeps this same name. For example, if kidney cancer spreads to the lungs, it is still kidney cancer, not lung cancer. Lung cancer would be an example of a secondary tumor.

Explanation:
The trait distribution most likely change over this time such that the plants with favorable traits, medium-tip leaves and drip-tip leaves will survive due to natural selection.
<h3>What is natural selection?</h3>
Natural selection is the process by which organisms which are better suited to their environment survive whereas those not suited die off.
The organisms that are suited to their environment possess special features which enable them to adapt to changes in their environment.
Considering the plants in the rainforest with different leaf tips:
- Trait A: medium-tip leaves
- Trait B: drip-tip leaves
- Trait C: wide-tip leaves
Since fungi grow in moist environments, it can be seen that plants with Trait C will be least favored to survive, while plants with Trait B will be most favored to survive by natural selection.
Thus;
- In year 1: the composition of plants is 50% have medium-tip leaves, 25% have wide-tip leaves, and 25% have drip-tip leaves.
- In year 5: the composition of plants is 50% have medium-tip leaves, 25% have wide-tip leaves, and 0 % have drip-tip leaves
- In year 10: the composition of plants is 25% have medium-tip leaves, 75% have wide-tip leaves, and 0% have drip-tip leaves.
In conclusion, plants with favorable traits will survive due to natural selection.
