Soy is a type of plant protein. This is great for vegetarians who are against eating meat but still need a source of protein. Some benefits of eating soy products (like tofu and soy milk) are mostly cardiovascular, lowering blood pressure since they are naturally cholesterol free and low in saturated fat.
The cell membrane of the plant and animal cells help them to maintain homeostasis. It regulates the particles that move in or outside the cell. All cell work in integrity to maintain homeostasis. The organelles also contribute to this process. Vacuole stores food for this, cell membrane acts as a barrier for foreign materials, mitochondria provide the cell with its energy, nucleus controls all the activity, cell wall protects the cell, cytoplasm maintains the integrity of the cell, ribosomes, and endoplasmic reticulum synthesize and transport the proteins required by the cell.
Answer A is better because
1. You only have 1 independant variable, the zooplankton
2. You take periodic and relevant observations of the Dependant Variable (amount of algae)
3. Other variables (that could otherwise mess with your results on the dependant variable) are kept constant, thus enforcing the effect the independant variable has on the dependant variable (which is what youre trying to observe).
