Answer;
Chlorine is an element while carbon (iv) oxide is a compound.
Explanation;
-An element is a pure substances that is made up of similar types of atoms. Elements unlike compounds can not be divided into simpler forms using chemical means. Examples of elements include; potassium, chlorine, helium, sodium, etc.
-Compounds on other hand are substances that contain more than one atom from different element that are combined together chemically. The atoms in a compound are in a fixed ratio. Compounds can be divided into simpler forms using chemical means. Example of compounds include; carbon (iv) oxide, water, etc.
Answer:
Hey brainer! Brownian Motion is the random motion of large particles caused by the motion of the much smaller molecules that are all around them. In the case above, the circles you see are the fat globules in milk suspended in water as viewed through a web-cam down a microscope. The globules vary in diameter from 0.5 to 5 micrometres. The water in which they are suspended is made of H2O molecules with are typically 0.0003 micrometres across. The picture below tries to capture scale – but I haven’t managed to draw the water molecules small enough. Brownian motion is the jiggling of the gigantic fat globules due to the motion of the tiny water molecules.

true is the correct answer
The goal of computer forensics is to obtain all the evidences available and then to analyse the evidence and determine what has happened. At the same time it goal is to produce admissible evidence without altering any of the information.
A, DNA fragments containing repeats are labeled with radioactive probes.
