Answer:

<u>Answer D. Scratching it with other materials</u>

Explanation:

Let's start eliminating some answers

Answer A; If you hit an object with a hammer, you will just figure out if that object can be broken with a certain amount of force. In most cases, this will not be helpful.

Answer B; When putting a material in an acid, many things could happen. This things that happen are called chemical reactions. Not every material will have a chemical reaction so this step could be useless.

Answer C; Chipping a piece off of a material will not grant you much information. Yes if may be easier to experiment will a smaller piece but the action by it's self is not useful.

Answer D; Scratching a material will another material can be very helpful. If you have two materials, labeled A and B, you can find out the Mohs hardness scale. If A is damaged by B, the hardness of A is less than B and vise versa. This can be very helpful when identifying materials.

So answer D makes the most sense

mrs_skeptik [129]
<span>adding a unit to move a susceptible group enough to prevent metabolism is known as shifting.
These phenomena happen especially for liposoluble organism circulating in blood like drugs an hormones.
these molecules circulating blood can be divided into two forms : 
The free-form: which is the active part, it circulates freely in the blood, but are easily metabolised.
The bound form: it can be bound to other molecules from the organisms depending on its affinity like proteins (albumin, glycoproteins). this form is not active but is prevented from metabolism.

Competition for bounding proteins can happen between two drugs for example. If they have a different degree of affinity for proteins, then the most affine will displace the less affine from the protein and bound it, and that is call shifting</span>

DNA<br>"Deoxyribonucleic<br>Acid"​
Zarrin [17]

Answer:

Details about DNA are given in the explanation section. Hope it will be helpful for you.

Explanation:

DNA, or deoxyribonucleic acid, is the hereditary element in humans and almost all other organisms. Nearly every cell in a person’s body has the same type of DNA. Most DNA is found in the cell nucleus (nuclear DNA), but a small quantity of DNA can also be found in the mitochondria (mitochondrial DNA or mtDNA).

The information in DNA is stored as a code made up of four chemical bases: adenine (A), guanine (G), cytosine (C), and thymine (T). Human DNA consists of about 3 billion bases, and more than 99 percent of those bases are the same type in all people.

DNA bases pair up with each other, A with T and C with G, to form units that are called base pairs. Each base is also attached to a sugar molecule and a phosphate molecule.  A base, sugar, and phosphate are called a nucleotide. Nucleotides are arranged in two long strands that form a spiral called a double helix.

A valuable feature of DNA is that it can replicate, or make copies of itself. Each strand of DNA in the double helix can serve as a pattern for duplicating the sequence of bases.
