What evidence supports the endosymbiotic theory?
The Amoeba, the paramecium, and the euglena ( These are unicellular Protozoans) produce electrical impulses that travel along their cell membrane. This is possible because they are specialized to use properties exhibited by all cells. These properties include ... A) Separation of the fluid environments inside and outside the cell B) Active transport of Na+ out of and K+ into the cell. C) Portal proteins that allow diffusion of Na+ and K+ back in to the cell D) Maintaining unequal Na+ and K+ concentrations on the two sides of the membrane. E) All of these are true
Explain why
1) Answer the following questions about a Vegetarian diet:
a) If applicable, what specific tissue or organelle would be affected by the diet. If no research is available, hypothesize which tissue or organelle may be affected and why.
b) Which nutrient (macro or micro) is the focus of this diet?
c) List the foods that would contain the nutrients that are the main focus of the diet.
