Fingerprint is the print of our finger, remote sensing are placed usually in locks in safety areas, it identifies the matching fingerprint and allows the people to enter, and in DNA barcode, location can be detected by remote sensing.
<h3>What is remote sensing?</h3>
Remote sensing is the identification of the sense of people, the data is feed to the device then according to the data it senses the presence and allow that people.
DNA barcoding is taking small fragment of DNA to find the progeny or its availability.
Thus, Remote sensing is typically used in locks in security areas to identify matching fingerprints and allow people to enter, and in DNA barcodes, location can be detected using remote sensing.

Answer:
neutral
Explanation:
There are three basic subatomic particles. These are;
- Protons (positively charged)
- Electrons (negatively charged)
- Neutrons (neutral)
A neutron has no charge unlike the proton and the electron. It is present in the nucleus and contributes to the mass of the atom.
Answer:
Metals tend to lose electrons in chemical reactions, as indicated by their low ionization energies. Within a compound, metal atoms have relatively low attraction for electrons, as indicated by their low electronegativities.
Answer:
This is a chemical symbol for Potassium Bromide
Answer:
Ionic character
A. PF₃ > PBr₃ > PCl₃
B. BF₃ > CF₄ > NF₃
C. TeF₄ > BrF₃ > SeF₄
Explanation:
The most electronegative element is fluorine, followed chlorine, phosphorous nitrogen etc.
- Atoms with high electronegativity tend to form negative ions.
- Ionic compounds formed between elements with high electronegativity difference.
- % ionic character is directly proportional to electronegativity difference.
- According to Pauling Scale E.n for F(4.0), O(3.5), N(3.0), C(2.5), B(2.0), P(2.19), Se(2.55) , Te (2.1), Cl(3.16) and Br(2.96)
- ΔE.N (Electronegativity difference) between( P and F = 4 - 2.19 = 1.81), (P and Br = 2.96 - 2.19 = 0.77) , (P and Cl = 3.16 - 2.96 = 0.2 )
- ΔE.N (Electronegativity difference) between( N and F = 4 - 3 = 1), (B and F = 4 - 2 = 2) , (C and F = 4 - 2.5 = 1.5 )
- ΔE.N (Electronegativity difference) between( Se and F = 4 - 2.55 = 1.45), (F and Te = 4 - 2.1 = 1.9) , (F and Br = 4 - 2.19 = 1.81 )
