The way in which the drugs like alcohol, antipsychotic drugs, antidepressants, amphetamines, opiates such as oxycodone, and MDMA (ecstasy) effects on the central nervous system (CNS). Introduction: Brain and the spinal cord make up the CNS. It is one of the most important systems in the body as it performs several functions crucial for survival. There are various drugs, which affect the CNS negatively and cause harmful effects on the body.

Question

Imagine you are a botanist. Below are characteristics of a never-before described plant species recently identified as part of the ‘All Taxa Biodiversity Inventory’ (ATBI). Field Notes: Specimen collected from shaded area along stream in South Cumberland State Park (Grundy County, TN). Laboratory Analysis: Body: Large leaves emerging from underground rhizome. Size: 63 cm Chromosomal Analysis: Plant body is diploid—chromosome number of 44. Lignin test: Positive Cuticle: Present Leaves: Present—large with branched veins. Underside has sori (containing haploid spores). Roots: Present—branch from the inside. Stem: Present—vascular tissue (xylem & phloem) present. Life History: Diploid sporophyte dominant generation. Haploid spores germinate into heart-shaped, haploid, gametophyte. Water required for fertilization; no seed is produced. Diploid zygote develops into sporophyte. Explain which domain, kingdom and phylum you believe this plant should be classified…
