The answer is; B.
Cells have different receptors on their surfaces that are responsive to particular signals (such as hormones). When a signal interacts with the particular receptor, a particular response is invoked in the cell. This signal may be produced even by a cell that may be far away from the target cells. This is how cells communicate with each other to maintain homeostasis in the body.
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
Answer: Two analogous structures are similar in phenotype and developed to perform the same function, despite not being inherited from a common ancestor. As so unrelated species may look related due to having analogous structures.
Explanation:
The answer requires looking at the meaning of the words 'theory' and 'law'. The formal definition of a theory is that it is a comprehensive explanation of a observed phenomenon supported by a lot of evidence. Law is a fact that is bound to be true in nature, example Newton's second law. However, a theory is subjected to continuous refinements based on the several new findings that happen with time. These refinements make the theory appear incomplete. As with the theory of evolution, a lot of research work is being put to understand the complex phenomenon of genetic inheritance of traits of behaviour. Unless there are evidences from nature for all the aspects of evolution in theory, it'll remain a theory and not become a law.
Answer is A) Yes, if scientists decide that enough evidence supports the theory.
