<h3><u>Answer;</u></h3>
Having untested DNA samples
<h3><u>Explanation;</u></h3>
- <em><u>DNA technology has a great and a wide variety of important uses, which ranges from,paternity testing, to matching the DNA samples of suspects collected at a crime scene, to matching relatives to a missing person's DNA.</u></em>
- However, <em><u>use of DNA in forensics may have negative consequences which includes, the backlogs of forensic evidence and also present of untested DNA samples which delays the whole process.</u></em>

An element have the same number of protons as electrons.
Therefore: if an element x (Lawrencium) has 103 protons, it has 103 electrons.
White blood cells structure are quite varied, and different kinds have different functions. These are a few options:
1. The flexibility of the plasma membrane allows bacteriophage and increases mobility in pursuit of invaders.
2. Beta cells put out chemical antigens to eliminate invaders chemically.
3. Various white cells display proteins on their plasma surfaces to communicate the composition of the pathogen.
4. White cells (unlike red blood cells) have a nucleus, which allows the synthesis of new chemicals in response to various invaders.
5. White<span> blood cells tend to have a higher surface to volume ratio than other cells because the are more amorphous. That would lead to a relative increase in the plasma membrane, which contains receptors for identifying.antigens. T</span><span>he white blood cells may be more receptive to detection of antigens due to a higher surface-to-volume ration.</span>
