Making up all living material, the cell is considered the building block of life. The nucleus, a component of most eukaryotic (nonbacterial) cells, has been known to be the hub of cellular activity for 150 years. Seen under a light microscope, the nucleus appears to simply be a darker region of the cell, but as we increase magnification, we find a hodgepodge of substances in the nucleus, which undergoes a flurry of activity leading up to and during mitosis, or cell division; see Figure 1.

## Problem

What is the sexy doll standing foot option? Due to the softness of TPE lifelike sex dolls, dolls with ordinary feet cannot stand. Otherwise, the skeleton inside the footboard may directly break the soles of the sexy doll’s feet. The standing feet option is that the feet are equipped with three metal bolt heads as an extension of the skeleton to support the doll’s standing. The sexy doll with the standing feet option can keep standing for a long time for photography, intimacy or storage. However, we don’t recommend that you leave your Real doll free-standing whilst unsupervised, as he/she could fall and be damaged. How to Use Standing Function Correctly sexy doll are not real people who have a cerebellum to maintain body balance. The three metal bolt heads at the bottom just play a supporting role, which is not particularly stable. So you need to find a wall or something else that the doll can rely on to keep the doll standing. This operation may take some time and you need to constantly adjust the posture to find the best balance. It is better for the real life sex doll to stand barefoot on the ground and put a soft cloth on the sole of the foot. When wearing shoes for the doll, wear a few more socks or use a hard insole to prevent the shoes from being damaged. You can also put leather insoles on the feet of the sexy sex doll first, and then put on stockings. Should you buy the standing feet option? For those with a foot fetish or a preference for the perfect figure, the three screws on the bottom will undoubtedly destroy the integrity of the feet. If it happens that you don’t need the doll to stand for a long time, non-standing feet option (regular feet) is the best choice. If you hope to store the sexy doll upright in the house, have sex whilst standing, or use the doll as a model, please choose the standing feet option. Notes: 1. The standing feet are the same as the regular feet(non-standing feet), but the ankles have been redesigned and the soles of the feet have been reinforced so that all dolls with the standing feet option can stand on their own. 2. The standing feet are rigid. They can be rotated downwards by 150°, but not upwards or side to side. 3. furry sexdoll is only recommended to wear flat shoes when standing. The high heel shoes can be put on the feet, but high heels cannot be worn when the doll is standing. 4. The standing feet option is available for sexy doll over 100cm.
