Answer:
They may have different phenotypes because of differences in their environments, such as nutrition and healthcare. Why might genetically identical twins have different phenotypes? Any genes on the same chromosome could be linked genes, whereas only genes on sex chromosomes can be sex-linked genes.
Explanation:
Answer:
True
Explanation:
Electrons that are in the first energy level (energy level 1) are closest to the nucleus and will have the lowest energy. Electrons further away from the nucleus will have higher energy. An atom's electron shell can accommodate 2n2 electrons, where n is the energy level.
Four binary ionic compounds that could be formed from each of these ions are;
- Zn^2+ - ZnCl2, ZnI2, ZnBr2, ZnF2
- Pb^4+ - PbF4, PbCl4, PbBr4, PbI4
- Br^- - MgBr2, NaBr, CaBr2, KBr
- S^2- - CaS, MgS, Na2S, K2S
<h3>What are binary ionic compounds?</h3>
Binary ionic compounds are those compounds that contain only two elements. The ionic compounds are those compounds that contain ions. The compounds are able to dissolve in water and they have high melting and boiling points.
Now, four binary ionic compounds that could be formed from each of these ions are;
- Zn^2+ - ZnCl2, ZnI2, ZnBr2, ZnF2
- Pb^4+ - PbF4, PbCl4, PbBr4, PbI4
- Br^- - MgBr2, NaBr, CaBr2, KBr
- S^2- - CaS, MgS, Na2S, K2S

Answer:
105
Explanation:
Density = mass/volume
therefore volume = mass/density
826/7.9=105 (To three significant figure)
