A teacher makes the analogy that stem cell research did for medicine what the Internet did for communication. What is meant by this analogy? Stem cells allow for communication between cells. Stem cells were a huge leap in technology that opened many doors. Stem cells were a setback in technology that restricted opportunities. Stem cell information is stored in databases online.

The analogy says that stem cells were important for medicine, just as the internet was important for communication, because if you look, thanks to the internet, different social networks and different media have emerged. Nowadays it helps a lot of people in different cases, like online classes for certain schools. Without the internet, people would still be talking in person, and in these quarantine times it would not be possible. And the internet also made it possible for strangers to connect, making multiple communities.

I hope I helped, even speaking only on the technology side.

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.
