The element starts off as 100%. half of 100% is 50% and half of 50% is 25%. the element has emitted 2 times the half life which is 10,000 x 2 = 20,000
the fossil bone is 20,000 years old
The prairies are ecosystems where the grasses, herbs, and shrubs are the dominant vegetation type. It is one of the most intensive crop producing areas with highly valued productive soils. The diet of the people who lived there would be based on corn wheat, rice, soybeans, bean, peas, etc.
On the other hand, people who live on rocky seacost will most likely consume seafood such as mussels and barnacles.
Step One - Obtain a clean microscope slide.
Step Two - Place a drop of liquid on the slide. This is the “wet” part of the wet mount. The liquid used depends on the type of cell being viewed:
If examining a plant cell, tap water can be used.
If examining an animal cell, physiological saline (or contact lens solution) must be used, because if plain water is used, the cell will explode from osmotic pressure. Unlike plant cells and bacteria, animal cells have no cell wall to structurally support them.
Step Three - Obtain the specimen to be used. Some introductory biology classics for viewing include:
Skin of an onion bulb: In order to view the cells, a very thin layer of skin must be obtained. Take a single layer of onion and bend it towards the shiny side. After it snaps, pull gently, and a transparent layer of skin, similar to Scotch tape, will appear.
Elodea leaf: Elodea leaves are two cell layers thick. The cells in one layer are smaller than the cells in the other, so elodea leaves can be used to better understand a microscope's depth of field.
Cheek cells: Human epithelial cells can be obtained by gently rubbing a toothpick on the inside of the mouth, and then swirling the toothpick in the physiological saline on the slide.
Pond water: Obtaining some water from a pond makes wet mount preparation a breeze, since the water and the specimens are both included.

Answer:
Yes it can. It can cause an overdose and can cause a seziure/stroke and you can die. Half the bottle and pretty much any mg per tablet honestly. Hope this helps :)
Explanation:
The spinal cord is in the backbone (aka spine). The spinal cord is part of the central nervous system
How I remember where the spinal cord is the root of the words spine and spinal cord is similar
Hope this helped!
