ctive transport is a process that moves molecules across the plasma membrane against heir concentration gradient. Why is active transport essential for cell survival, and what rould happen if active transport mechanisms failed? It maintains concentration gradients of ions and other molecules necessary for cellular functions; failure would disrupt cellular homeostasis, leading to potential cell death. It ensures the cell remains hydrated; failure would lead to dehydration of the cell. It increases the membrane's permeability to water; failure would prevent water from entering the ce It helps in producing energy for the cell; failure would result in ATP depletion. It allows the cell to move large molecules out: failure would cause the cell to lose all its contents.

Consider the balanced chemical reaction below: $2Na_2C_2O_4(aq) + SnF_4(aq) \rightarrow 4NaF(aq) + Sn(C_2O_4)_2(s)$ A. Calculate the mass of $Sn(C_2O_4)_2$ that can form when 17.75 g of $Na_2C_2O_4$ is mixed with excess $SnF_4$ by filling in the numerical values, and units, in the following dimensional analysis: $\boxed{Na_2C_2O_4} \times \boxed{\frac{1}{134 g Na_2C_2O_4}} \times \boxed{\frac{1 mol Sn(C_2O_4)_2}{2 mol Na_2C_2O_4}} \times \boxed{\frac{294.7 g Sn(C_2O_4)_2}{1 mol Sn(C_2O_4)_2}} = \boxed{Sn(C_2O_4)_2}$
