Amicrobial agent that can survive processing by water treatment plant is: a. cryptosporidium parvum b. vibrio cholerae c. e. coli d. tetanus e. dracunculus medinensis

a. Cryptosporidium parvum

Explanation:

Cryptosporidium is a protist parasite that has a spore phase. These spores are called oocysts. In this state the parasite can survive for long periods outside the host and can also resist many common disinfectants. Especially chlorine-based disinfectants. Due to this resistance, water treatment to remove Cryptosporidium in general is based on coagulation followed by filtration or boiling.

water is a polar molecule. a chemical bond is a force of attraction between atoms or ions. bonds form when atoms share or transfer valence electrons. atoms form chemical bonds to achieve a full outer energy level, which is the most stable arrangement of electrons. so, false

explanation:

in h2o molecule, two water molecules are bonded by a hydrogen bond but the bond between two h - o bonds within a water molecule are covalent. the greater the electronegativity difference, the more ionic the bond is. bonds that are partly ionic are called polar covalent bonds. nonpolar covalent bonds, with equal sharing of the bond electrons, arise when the electronegativities of the two atoms are equal.

the correct answer to this question is #5
