    Climate changes will trigger growth of pathogens, causing outbreaks of disease
    Increased cloudiness due to higher air temperatures causes microhabitats such as leaf mats to be optimal for chyrid

    True
  • Amniotic Egg: Match the egg characteristic and definition?(albumin, Chorion, Amnion, Allantios, Yolk)
