The best way to determine the presence of halogens is by adding a silver nitrate solution to the solvent. This is because all halogens, except for fluorine, produce a precipitate with silver nitrate solution.Chlorine produces a white precipitate, bromine produces a pale cream colored precipitate and iodine produces a yellow colored precipitate.
If further testing is required, concentrated sulfuric acid may be added. The sulfuric acid will produce misty fumes with fluorine and chlorine, brown fumes with bromine and purple fumes with iodine.
hope this helped :)

Explanation:
People who are insecurely attached are unable to maintain consistency between the actions that they carry out and the thoughts and emotions that manifest. They go from submission to aggression, or from closeness to distance, with disconcerting ease. Not even they understand what’s happening to them. The same acts were being witnessed by Latoya who basically ignored her mother.
A segmented viral genome can facilitate rapid evolution of new viral strains.
Explanation:
The genome of the virus contains both coding and non-coding sequences. Segmented viral genomes are separate unit of nucleic acid in a virion particle and they undergo reassortment.
When the genome of the viral DNA gets segmented, the multiple DNA strands. When two infection with 2 strands of virus takes place simultaneously the two strains may get swapped or cross over. This leads to new strand and hence evolution happens.
examples of such virus are : Birnaviradae, reoviridae

Study one small part at a time, over and over. Ask questions and stay after school. Do research and flash cards. All the help you need is there. You have to do your part and dedicate yourself into your class. There isnt a sufficient way to cram information in when you have a test next day, but next time you should do an little something helpful called, s͟t͟u͟d͟y͟i͟n͟g͟.
