An important group of peripheral membrane proteins are enzymes, such as the phospholipases that attach the head groups of phospholipids leading to the degradation of damaged membranes. What properties must these enzymes exhibit

Explain how sequences of amino acids in proteins can be used to reveal relationships among organisms.

Amap's orientation is typically determined by an

The diagram below shows the layers of a rock having a trilobite: a rock column labeled rock is shown. the column has three layers. the bottommost layer of the rock has one shaded rhomboid shape, the middle layer has a rhombus with a diagonal along with two identical organisms marked as, trilobite, in the key, the top layer has two semicircles. a key is shown on the right side of the diagram. the shaded rhombus is marked as a, the rhombus with the diagonal is marked as b, the semicircle is marked as c which statement about the rock fossils is true?
