Answer:
Answered below
Explanation:
On piercing his foot, the pain receptors called nociceptors, found in the skin, are activated. Nociceptors exist at the nerve endings of the primary afferent neurons. Signals travel along the first order neurons which have cell bodies within the dorsal root ganglia of the spinal cord. In the dorsal root ganglia, the signals are taken up at the synapse with the second order neurons which have cell bodies in the nuclei of the cranial nerves within the brainstem. These neurons ascend cranially in the spinothalamic tract to the thalamus. The third order neurons lie within the ventral posterolateral nucleus of the thalamus. They terminate at the somatosensory cortex where the signals are being processed and returned as a sensation of pain.
Answer:
Only one species can fill an ecological niche because each niche is destined exclusively for each species, since its structure, physiology and behavior determine it.
Explanation:
An ecological niche is the way in which each species relates to its environment, to other species and takes advantage of the resources available for its development, being an exclusive and individual characteristic of that species.
The ecological niche is a concept that many consider abstract, since it is unique for a species. Each species has a physical structure, functioning and behavior that differentiates it from the others, which leads it to occupy a certain place within an ecosystem, which would be its ecological niche.

Answer:
A)
Explanation:
the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct.Also During the process of photosynthesis, cells use carbon dioxide and energy from the Sun to make SUGAR molecules and oxygen. These sugar molecules are the basis for more complex molecules made by the photosynthetic cell, such as GLUCOSE.
therefore the answer would be A
<h2>Functions of elbow joint </h2>
Explanation:
- The elbow joint should be rotated laterally.
- This is because the elbow is basically a pivoted joint, however, it has the extraordinary capacity to turn the distal arm in pronation and supination
- These exceptional movements, alongside a wide scope of dynamic exertional powers, incline the elbow and its structures to critical wounds, especially with tedious movements
- Understanding the life systems and the physical powers of development will help in diagnosis
- Hence, the right answer is "elbow joint should be rotated laterally on an (AP), when the radial head is slightly superimposed over the proximal ulna on the first effort"
True every living thing needs energy
