sperm capacitation. acquisition of the capacity to penetrate an ovum, not present at the time of delivery of the spermatozoon, and which requires a period of incubation in the female tract. It involves increased metabolic activity and motility and the removal of a chemical decapacitation factor from the spermatozoon.
Exhibition marks 40 years of Rubik's Cube. 3. Solve the white corners. With the white cross on the top face, you must then solve the white corner pieces. Corner pieces will have one white side plus two other colours. 4. Solve the middle layer, so the bottom two layers of your cube match in colour.5. Solve the top layer. The first stage of this step is to try and get a yellow cross on the top face of your cube. Next, you should try and get all the yellow on the top face. 6. Position the yellow corners correctly.xhibition marks 40 years of Rubik's Cube. 3. Solve the white corners. With the white cross on the top face, you must then solve the white corner pieces.

Step 3: The second layer of the Rubikâs Cube. Now we will solve the second layer of the Rubikâs Cube. Remember that the center pieces are fixed, so thereâs no need to place them.Bear in mind that you will have to repeat this step 4 times to solve the Rubikâs Cube, once for each edge.1  Hold the Rubikâs Cube in a way the white face is the top one and the yellow face the bottom one.ou will not be able to solve this case directly. However, if you perform the movements specified, you will get another case for this step. Repeat this step with the 4 edges until you solve the second layer. Now itâs time to take a look to the solution of the second cross of the Rubikâs Cube.
