Bovine spongiform encephalopathy (bse) is a slowly progressive, degenerative, fatal disease affecting the central nervous system of adult cattle. it can be transmitted to humans when the infected flesh of cattle is ingested. what is bse thought to be caused by? a) protozoab) prismsc) prionsd) priori

The correct option is C) Prions

Explanation:

Bovine spongiform encephalopathy (BSE)  or Mad Cow Disease  is a disease which occurs due to transmissible particles known as prions. Prions cannot be considered as living organisms as they do not acquire many of the living characteristics. They are just considered as a protein which gest converted into an activated, toxic form  as soon as they encounter a host cell. This toxic protein harms the central nervous system (CNS) of the cow host and is transmissible.

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.
