Ferns reproduce by spores, Conifers reproduce by seeds. Differences also exist in the root and stem structure. Neither Ferns nor Conifers have true leaves, Ferns have fronds and most Conifers have needles.
Hope this helped.
The continental drift affects living organisms in that it causes changes in climates which puts selective pressure on organisms, causes changes in habitats, including when large amounts of shallow marine habitat were lost in the formation of Pangea. Additionally continental drift may cause an increase or decrease in competition among different species and also it happens so slowly that it does not affect living organisms
Answer:
<h2>Gray matter: the gray matter is arranged intohorns: The posterior horn extends towards the dorsal root, the anterior horn extends towards the ventral horn, and the lateral horn lies between the posterior and anterior horns.
</h2>
Explanation:
The posterior horn is associated with the sensory nerve cells, the anterior horn is associated with the somatic motor neuron, and the lateral horn associated with the ANS ( autonomic nervous system).
Posterior horn:
Sensory neurons pass through the dorsal root ganglion after that the dorsal root and in the gray matter the neurons synapse to inter neurons in the posterior horn or may continue to the white matter and then enter the spinal cord.
Anterior horn:
The motor portion of the nervous system has two parts; i) the somatic motor system and the ii) autonomic nervous system. The somatic motor neuron stimulates the skeletal muscle with stimulation. The somatic motor neuron cell bodies (part of verve cell) are in the anterior horn of the gray matter.
Lateral horn:
The autonomic motor neuron send stimulation to smooth muscle, cardiac muscle, and glands etc. The cell bodies( part of nerve cell) of the autonomic motor neuron are in the lateral horn of the gray matter.
