Trace elements,such as iron and magnesium,are present in living things in very large amounts?

Question

true or false;if false what would the word(s) be instead of very large amounts?

Answer 1

false - fairly small.

The human body contain 3-5g of iron, half of which is usually found in hemoglobin (red blood cells)

Magnesium on the other hand.. daily "requiriment" is 350mg. This is used up by the body to catalyze reactions.

Even though there is more than iron, compared to the rest of the things that make the body, they are small trace amounts.

hope that helped!

Answer 2

False; small.

Trace elements, though essential to life, are found in minute quantities. Some trace elements would be iodine and iron. Without these elements, illnesses such as groiter [lack of iodine] may result.

Answer 3

I sympathize with your desire to have a child but this is a Bad, bad BAD idea! Legally: Not only can your friend get fired if caught, in most places this is a felony. And you are an accessory. Unless you want to have a baby in jail, forget it. Biologically: There is a reason in vitro fertilization is a low yield proposition: The conditions do not favor impregnation. That is why it usually takes a number of attempts. Let's face it - the "usual" way of fertilization usually takes a several attempts (on average). Ethically: People who donate sperm do so under very strict conditions and under the assurance that their genetic material will be used appropriately. They have a right to have that expectation fulfilled. And what would you tell your child? That they were the product of a crime? Please reconsider.

Answer 4

by definition, a "trace" element is not present in large amounts. Mg, and Fe, are NOT trace elements. they are essential nutrients
