Charles Darwin theorized that all species undergo a natural cycle of evolution in order for the species to survive and thrive within its given environment. In the case of a catastrophic event, Mother Nature will naturally find a way to support life and the organisms that are within her care.
A scientific theory can always be disproved if someone comes along with better evidence which shows another theory is true. However, most other theories are small improvements on existing ones. Evolution and natural selection (the theory that animals' populations change over time because their environment encourages specific different features for individuals that happen with mutation) was an improvement on the existing "theory" that animals were built to be fit for their environments. The earth rotating around the sun was a theory improving on the idea that the sun and the earth move around so that it looks like the sun moves around the earth. All of these happened because there was evidence, so while theories aren't always absolutely true, many modern theories are typically well-tested and if they aren't, they are usually refered to as hypotheses or models (although models can sometimes also be theories, like the Standard Model)
NERVES CORE formed by combining the root of the ventral horns coming out of the front of the dorsal sensory root extending from the dorsal horn. <span>Cranial Nerves - 12 pairs. They extend symmetrically through the opening at the skull base. These nerves innervate the head, except for 10 and 11 Every nerve may be sensory, motor or mixed.</span>
Skully: visual, olfactory, oculomotor, trochlear, trigeminal abducens, facial, vestibulocochlear, glossopharyngeal wrong, sublingual
Function: receiving stimuli are responsible for memory and intelligence, stimulating muscle contraction head and neck allowing movement of the head, eyes, and tongue, and change facial expressions
Core: cervical, thoracic, lumbar, Cross, coccygeal
These functions:
- Receiving the stimuli from the skin, mostly on the trunk and extremities
- Stimulate the contraction of the trunk muscles primarily and ends
Sound intensity, also known as acoustic intensity, is defined as the power carried by sound waves per unit area in a direction perpendicular to that area. ... One application is the noise measurement of sound intensity in the air at a listener's location as a sound energy quantity.
A balance is used for measuring mass.
