Both CO2 and SiO2 exhibit covalent bonding, so why is CO2 not a covalent-network solid? If a covalent bond only occurs within a molecule, then why does it occur between molecules in glycosidic linkage? Why are compounds called molecules if some compounds are bonded ionically, which is not ...

Animals were euthanized with CO2 on day 70. The joints were dissected, femur and tibia were separated with the peripatellar joint capsule containing the patella, parts of the synovium and the patellar tendon still connected to the tibia. All the surrounding tissues including ligaments and menisci ...
Functionally, galectins mediate a variety of biological processes, including cell differentiation, adhesion, and apoptosis5,6, and they also have impacts on innate and adaptive immunity as they are key determinants of acute and chronic inflammation, immune tolerance, and host-pathogen interactions4,7...
Is a C-Cl bond polar covalent or nonpolar covalent? Both SO2 and CO2 have polar covalent bonds. However, one of these molecules is polar and the other is nonpolar. Which one is nonpolar and why? Are the bonds in PCl3 polar covalent, nonpolar covalent, or largely ionic? ...
