Answer:
Index fossils
Explanation:
The index fossils are the fossils that come in very handy for the geologists when it comes to identifying or dating rock samples or other fossils. The reason for this is that the index fossils have already been dated. They are fossils that are very commonly found, wide dispersed, are easy to be identified, and are limited to only a certain geological period. These characteristics make them an excellent indicator for the dating of the rock layers in which they are found, or the fossils found in the same layers with them, without conducting further examinations.

The correct answer is: A. stimulates secretory activity
Parasympathetic nervous system is a part of the autonomic nervous system (a division of the peripheral nervous system (PNS), so it means it regulates unconscious actions in an organism. Parasympathetic system is known as a system for stimulation of "rest-and-digest", when the body is at rest (differ than sympathetic which is active for fight-or-flight response). Parasympathetic system works usually after the meal and it is involved in the functions such as, secretory activities (salivation, lacrimation ), urination, digestion and defecation..
The stimulus modality is one in which the body response to the stimulus and respond in each way accordingly. Two different stimulus can be used at two different time to sense different operation
Explanation:
There are five different types of sensory modalities and they are the visual auditory gustatory olfactory and the receptors. They function to identify the taste, smell, heat, light and sound. When a specific function is done the following sensory receptors are activated and they respond to the stimulus.
The sensory receptors at the finger tip are stimulated when we touch a hot or a cold object this is one type of function. On the other hand the synapses which occurs at the brain are due to the modulus of the brain activities like vision and responding to the activities.
