<span>In physical chemistry, the van der Waals forces is the sum of the attractive or repulsive forces between molecules other than those due to covalent bonds or to the electrostatic interaction of ions with one another or with neutral molecules. Van der Waals forces are relatively weak compared to normal chemical bonds, but play a fundamental role in fields as diverse as supramolecular chemistry, structural biology, polymer science, nanotechnology, surface science, and condensed matter physics.</span>
Answer:
All angiosperms produce flowers, reproductive structures that are formed from four whorls of modified leaves. Most flowers have showy petals to attract pollinators, bribing insects and other animals with nectar, to get them to carry the male gametophyte through the air to another flower.
Answer:
Scientists must collect accurate information that allows them to make evolutionary connections among organisms. Similar to detective work, scientists must use evidence to uncover the facts. In the case of phylogeny, evolutionary investigations focus on two types of evidence: morphologic (form and function) and genetic.

Answer:
Conservation protects species from extinction, maintains and restores habitats, enhancing ecosystem services and protecting biological diversity
(WIKI but I reworded it)
Explanation:
WIKI and conservation is protecting species which leads to many things like the examples above.
