Afferent nerve fibers carry signals from the somatic receptors to the posterior horn of the spinal cord or to the brainstem. So i beleive it is 4 but not too sure. Hope this helped a bit (:
Even though Eubacteria and Archaebacteria look similar, differences in their ribosomal RNA led to their classification into different domains. They are domains of the old kingdom Monera.
<h3>What are Archaebacteria and Eubacteria? </h3>
Archaebacteria and eubacteria represent two different domains of the old kingdom Monera.
Monera is formed by unicellular prokaryotic microorganisms that do not have membrane-bound organelles and cell nuclei.
Both Archaebacteria and Eubacteria exhibit sequence variation in their ribosomal RNA, which can be used to classify them.

It would result in reducing the sunlight it’s getting, so it would be harder for photosynthesis to take place
Answer:
Crossing-over is the exchange of genetic material between homologous chromosomes. It results in new combinations of genes on each chromosome. When cells divide during meiosis, homologous chromosomes are randomly distributed to daughter cells, and different chromosomes segregate independently of each other.
