3.010) ____ tigers are in the same family as the lynx and the same genus as the lion. which of these is the tiger more closely related to?
a. lynx
b. lion

Explanation:

• 3.08: Invasive species are known to cause harm to ecosystems. Alien, non - native, and exotic species may not always be dangerous. For example, some non - native species can be part of a healthy ecosystem if they are well - integrated.
• 3.09: In binomial nomenclature, the genus name is capitalized and the species name is in lowercase. So, for the gray wolf, the correct scientific name is Canus lupus.
• 3.10: In biological classification, the genus level is more specific than the family level. Since tigers and lions share the same genus, they are more closely related than tigers and lynx (which share the same family but different genera).

Answer:

• 3.08: D. invasive
• 3.09: D. Canus lupus
• 3.10: B. lion
