Answer:
0.00508368 grams
Explanation:
From the question we are told that the daily allowance for infants and children is 8.00 × 10⁻⁶ mole of copper per kiogram of body weight.
Since this value is given in moles, we have to convert it to mass
Molar mass of a compound = mass in grams / no of moles of the compound.
So, Molar mass of copper = 63.546
No of moles of copper per kg = 8.00 × 10⁻⁶ mole
63.546 = mass/ 8.00 × 10⁻⁶ mole
Cross multiply
Mass of copper per kg body weight = 8.00 × 10⁻⁶ × 63.546
= 0.000508368 grams
Hence, the daily allowance of copper required for infants or children per kg of weight = 0.000508368 grams.
For a 10 kg infant this is calculated as:
If 1 kg per weight of an Infant = 0.000508368grams
10 kg =
We cross multiply
10 kg × 0.000508368 grams
= 0.00508368 grams.
Therefore, the mass of copper required per day for a 10 kg child is 0.00508368 grams
Adults—0.1 milligram (mg) two times a day, taken in the morning and at bedtime. Your doctor may adjust your dose as needed. The usual dose is 0.2 mg to 0.6 mg per day, divided and given two times a day.
Answer:
The answer to the question: In what part of the spinal cord would you expect to find myelinated axons, would be, in the white matter of the spinal cord.
Explanation:
The spinal cord, the roadway and connection between the brain and the rest of the body, and a vital part of life itself, is formed by covering tissue, fluid, and most importantly, by the neuronal bodies and axons that form the entire system of the CNS, and ANS, and which also connect these systems with the PNS (peripheral nervous system), and the different organs. One visual characteristic of the cord is it having two colors, white and gray. The white matter surrounds the gray matter. The reason for this white color in the white matter, which is really the connecting filaments that go up and down the CNS, and connect with the gray matter, is that white matter neurons and axons are covered by myelin, an insulating and cushioning covering that surrounds the cell´s axons and also helps the nerve impulses move much faster and with higher precision, than in the white matter.
