1. El Lipotón es un pigmento brillante y blanco que se utiliza en pinturas de interior de base acuosa y consiste en una mezcla de BaSO4 y ZnS. Cuántas moléculas se producirán de ZnS, si reaccionan 0,275 mol de ZnSO4 y 31,5 gramos de BaS al 85% de pureza, si la reacción tiene una eficiencia del 75% BaS (ac) + ZnSO4 (ac) → ZnS (s) + BaSO4 (s)

Arational expression has been simplified below. (x-5) (x+1)/3(x+1) = x-5/3 for what values of x are the two expressions equal

Ry was studying two populations of the same species of lizards. one population lived on an island and the other lived on the mainland. both populations were affected by a hurricane that hit the island and the mainland with equal force. a year later, henry was testing the gene frequency and saw a decrease in genetic variation in the island species, but not in the mainland species. which best describes a conclusion he might have reached? gene flow greatly affects small populations, but large populations can recover. genetic drift greatly affects small populations, but large populations can recover. gene flow greatly affects large populations, but small populations can recover. genetic drift greatly affects large populations, but small populations can recover.

True or false: (a) the strings of little red dots represent carbohydrates. (b) the model is called a bilayer because there are two main types of molecules present, lipids and proteins. (c) the many black lines represent amino acid tails. (d) this model shows membrane transport. (e) the blue ovals are hydrophobic. (f) the blue ovals represent phospholipid heads.
