Answer and explanation:
The meninges
There are actually 3 parts—dura mater, arachnoid, and pia mater.
The brain is soft and mushy, and without structural support it would not be able to maintain its normal shape. In fact, a brain taken out of the head and not properly suspended (e.g., in saline solution) can tear simply due to the effects of gravity. While the bone of the skull and spine provide most of the safeguarding and structural support for the central nervous system (CNS), alone it isn't quite enough to fully protect the CNS. The meninges help to anchor the CNS in place to keep, for example, the brain from moving around within the skull. They also contain cerebrospinal fluid (CSF), which acts as a cushion for the brain and provides a solution in which the brain is suspended, allowing it to preserve its shape.
The outermost layer of the meninges is the dura mater, which literally means "hard mother." The dura is thick and tough; one side of it attaches to the skull and the other adheres to the next meningeal layer, the arachnoid mater. The dura provides the brain and spinal cord with an extra protective layer, helps to keep the CNS from being jostled around by fastening it to the skull or vertebral column, and supplies a complex system of veinous drainage through which blood can leave the brain.
The arachnoid gets its name because it has the consistency and appearance of a spider web. It is much less substantial than the dura, and stretches like a cobweb between the dura and pia mater. By connecting the pia to the dura, the arachnoid helps to keep the brain in place in the skull. Between the arachnoid and the pia there is also an area known as the subarachnoid space, which is filled with CSF. The arachnoid serves as an additional barrier to isolate the CNS from the rest of the body, acting in a manner similar to the blood-brain barrier by keeping fluids, toxins, etc. out of the brain.
Answer:
Has the genetic disorder
Explanation:
Recessive gene are genes that are expressed phenotypically only in the homozygous condition. Homozygous is a condition where an organism contains identical alleles in homologous chromosomes. When a person is homozygous recessive for a recessive genetic disorder, then this genotype means that person has the genetic disorder since they have the identical allele.
B water pollution is the answer
Answer: d. High biodiversity in the understory.
Explanation:
The taiga or boreal forests are the largest biome in the world. These can be found in the regions of North America, Alaska, and United States. These regions exhibit extreme weather conditions. Typically long winters and moderate to high precipitation. The soil is permafrost and nutrient poor as no new organic matter can be added up to the soil due to it's freezing condition. The plant growth is scanty and biodiversity is low because organisms are incapable of surviving in the harsh weather conditions.
