C. ACTING AS A SHOCK ABSORBER FOR THE BRAIN AND SPINAL CORD</h2>
Explanation:
Meninges are tissues that provide protection, support and also serve metabolic roles for the nervous system. The cerebrospinal fluid is the fluid of the central nervous system and serves as protection, gives buoyancy to the brain, assists in excretion of waste products of metabolism from the brain.
These meninges are of three membranes; the dura mater which is the outer membrane; the pia mater which is rich in blood vessels and the arachnoid mater which keeps the brain in the cerebrospinal fluid. The meninges, along with the cerbrospinal fluid serves to cushion the brain and spinal cord preventing shocks. The pia mater layer of the meninges provides for the delivering of oxygen directly into the CNS and protects the brain from infections through the action of the leucocytes in the blood.
B. Fructose is an example of a carbohydrate. Carbohydrates are categorized as organic molecules.
The golgi body are membrane bound organelle which are found in eurkaryotic cells.They are responsible for packaging of proteins in cells. The golgi body is made up of series of flattened, stacked pouches called cisternae. Protein must pass through these cisternae as they move form the endoplasmic reticulum to their destination via golgi body. As they move through the series of the cisternae, they are appropriately modified and packaged for various destinations within the cell.
Answer: A) They are rearranged.
Answer:
The investigation of the Hudson River is an example of scientific inquiry because it develops testable questions such as this; <em>How might a zebra mussel invasion affect the Hudson River ecosystem?</em>
All the other elements of scientific inquiry were applied.
Explanation:
Developing and using models: Scientists developed ways to check for changes in the river using the data available to them.
• Planning and carrying out investigations: Several scientific institutes have planned and carried out investigations to determine reasons for the return of the Zebra mussels.
• Analyzing and interpreting data: Graphs are plotted to evaluate to draw a relationship between the zooplankton and the Zebra mussels.
• Using mathematics and computer technology
: Mathematical measurements were done to analyze the sizes of the Zebra mussels.
• Constructing explanations
: Explanations were proposed as to why the Zebra mussels were not eating up them. It made sense to them that more Zebra mussels would result in more Zooplanktons
• Engaging in argument from evidence
: They could argue from the evidence that blue cobras were eating up the Zebra mussels
• Obtaining, evaluating, and communicating information: After scientists have obtained their information, they endeavor to communicate them by publishing them in scientific papers and journals.
