helium molecules are much smaller than the molecules of wood pulp that make up the structure of paper. Thus helium gas will quickly dissipate through the paper itself, and into the environment without producing the necessary "lift".
Inhaling helium to make your voice different may be fun but you really should never do so. Doing so could be dangerous, especially if done to excess. This is due to the displacement of oxygen needed for respiration. Inhaling helium from a balloon is not as quite dangerous as doing so directly from a helium cylinder (the ones you see at stores to blow up balloon). It could fatally can rupture the tissue in your lungs. I recommend consulting a local doctor.
When the balloon is rubbed with wool, it gains a negative charge while the tissue paper remains positively charged. Opposite charges attract, causing the tissue paper to stick to the balloon. This is due to the transfer of electrons from the wool to the balloon, creating an electric charge imbalance between the two objects.

Yes, small pieces of tissue paper would likely stick to a rubbed balloon because the balloon becomes charged with static electricity when rubbed, creating an attractive force between the balloon and the tissue paper. This attraction is due to the transfer of electrons from one surface to another, resulting in static cling between the two materials.
Yes, but it has less lifting power than helium and is very caustic to skin, eyes and lung tissue.
Tissue-expander. A tissue-expander is an elastic material formed into a sac that is then filled with fluid or air so it expands like a balloon. The expander is placed under the skin and is filled, stretching the skin. Expanders are most often used to prepare a site for a permanent implant. Expanders are also used to assist in the repair of scars and the removal of tattoos by stretching the skin, removing the expander, removing the scar or tattoo, and suturing the skin edges together.
Compared to what ? Here's something to think about: There are some bits of tissue lying on the table on a dry day. You rub a balloon against your sweater a few times, and then you pass the balloon low over the bits of tissue. In response to the electrostatic force of the charged balloon, the bits jump off the table and up to stick to the balloon ... even though the gravity of the whole Earth is pulling them down.
The systemic veins and heart transfer waste-filled blood from the tissues into the pulmonary circulattion. The sytsemic veins bring waste-filled blood to the right atrium, which pumps it into the right ventricle, which pumps it into the pulmonary circulation.
The epidural space is the space in the meninges that is filled with adipose tissue. This space is located between the dura mater and the vertebral canal, providing cushioning and support for the spinal cord.
Fibrous and fatty tissue
When the original tissue has been completely decomposed and the space filled in by mineralization.
