Humans can affect the cycling of materials in an ecosystem through activities such as burning fossil fuels and wood. True or false

Here's an answer that might help you! I hope this helps! Like most biogeochemical cycles, human activities are capable of altering the natural conditions of the nitrogen cycle. The two activities that are primarily responsible for these alterations are the use of fossil fuels and the addition of nitrogen to fertilizers.

Explanation:

in addition to spreading humanist ideas, erasmus has contributed to criticism of corruption in the church.

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.
