Because there is insufficient evidence to support the idea that all chimpanzees use tools. the scientist would need lots of hard evidence supporting this conclusion (lots of chimpanzees using tools)
The answer is Macrophages. White blood cells also the leukocytes are the cells of the immune system that are involved in protecting the body against both infectious disease and foreign invaders. All white blood cells are produced and derived from multipotent cells in the bone marrow known as the hematopoietic stem cells. Macrophages are important cells of the immune system that are formed in response to an infection or accumulating damaged or dead cells. They are large, specialized cells that recognize, engulf and destroy target cells.

An implantable cardioverter-defibrillator or automated implantable cardioverter defibrillator is a device implantable inside the body, able to perform cardioversion, defibrillation, and pacing of the heart. The device is therefore capable of correcting most life-threatening cardiac arrhythmias.
Explanation:
The most internal layer of the epidermis is the stratum basale which contains melanocytes. Melanocytes produce melanin to protect the DNA. The cells of the stratum basale are the only cells that are capable of cell division. The stratum basale is attached to the underlying dermis. The stratum spinosum is superficial to the stratum basale. Stratum granulosum is superficial to the struatum spinosum. The stratum granulosum is three to five layers thick and contains keratohyalin granules, which produce keratin, a water proof protein.Stratum lucidum is superficial to stratum granulosum, but only in thick skin, which is on the palms and soles. Stratum corneum is about 25 cells thick and is the most superficial layer. It is dead and the cells are completely filled with keratin, which is waterproof. The many layers of dead skin protect from abrasion and are the first line of defense against any foreign bacteria, debris or virus.
