Motor neurons carry impulses to the effectors in the body, which are the muscles or glands that produce a change based on a stimulus sensed by the receptors. The motor neurons "innervate" muscle fibers, which essentially means that they cause them to move. The fewer the muscle fibers associated with a motor neuron, the more precise are the movements of those fibers. Having to control a small number of fibers, the neuron is able to coordinate more dexterous motions. An example of a region where there are not a lot of muscle fibers related to each neuron is in your fingers.
The force required to prevent the movement of water across a selectively permeable membrane is osmotic pressure. The plasma membrane forms a vesicle around the substances to be transported, and the vesicle around the vesicle is taken into cells.
Osmotic pressure depends on both the pressure gradient and concentration gradient. This is only affected by the temperature and concentration of solute, each affect the movement of water across a membrane.
Higher the concentration is higher temperature increases osmotic pressure, which produced or associate with osmosis and dependent on molar concentration and absolute temperature. Hydro-static pressure forces fluid out of the capillary , osmotic pressure draws fluid back in.

Answer: Lungs
Explanation: The pleura encloses each lung by a double layered serous membrane
Mitochondrial DNA (mtdna) recovered from a fossil hominin from sima de los huesos in northern spain shows connections to the mtdna of the Denisovans.
The Sima de los Huesos showed distinctive proof of DNA survival over an extended period of time. Based on the enzymatic amplification of a few short mitochondrial DNA (mtDNA) fragments from Middle Pleistocene cave bear bones. Given that the Sima de los Huesos fossils have Neanderthal-derived characteristics (such as in their dental, mandibular, midfacial, supraorbital, and occipital morphology), it is unexpected that the mtDNA from these fossils has a common origin with Denisovan rather than Neanderthal mtDNAs.
