<span>The tundra and the desert are very similar in one important way. Each of these biomes has low rainfall and available water, this results in plants in each environment that have adapted in similar ways. It causes these plants to have a waxy coating on the leaves which aids in preventing them from drying out.</span>
Answer:
1)Ionic bond, also called electrovalent bond, type of linkage formed from the electrostatic attraction between oppositely charged ions in a chemical compound. Such a bond forms when the valence (outermost) electrons of one atom are transferred permanently to another atom.
2) The atom that loses the electrons becomes a positively charged ion (cation), while the one that gains them becomes a negatively charged ion
3)onic bonds are important because they allow the synthesis of specific organic compounds. Scientists can manipulate ionic properties and these interactions in order to form desired products. Covalent bonds are especially important since most carbon molecules interact primarily through covalent bonding.

Remember the process by which plants make their food
The population would decrease rapidly or they would have to relocate.
Answer:
1. Polar 2. Hydrogen bonding 3. Cohesion 4. Surface tension
Explanation:
1. Water is a polar molecules due to the presence of unbalanced charges in its covalent bond.
2. This unbalanced charges causes the molecules to be polar and thus form hydrogen bonds with nearby molecules due to their opposite charges. The hydrogen atom carries the positive charge while the oxygen atom carries the negative charge. The opposing charges thus causes hydrogen and oxygen atoms in nearby molecules to be attracted to each other.
3. This attraction of the water molecules to each other is called cohesion. Cohesion is the force of attraction between similar molecules and this force of attraction is called a cohesive force.
4. Since the water molecules are attracted to each other due to a cohesive force, this cohesive force causes a thin film to form called surface tension. Thus, surface tension is the ability of the surface of a liquid to resist external forces due to cohesive forces in its molecules and thus form a thin film.
