Question

The cacti have developed spines that keep predators from eating them.
a: environmental factors.
b:genetic factors
Maple tree seed pods are shaped in a way that lets them fly through the air to germinate in a new location.
a:environmental factors.
b:genetic factors
Coconuts float in the water and this trait has helped them to spread to multiple islands.
a:environmental factors.
b:genetic factors
Some flowers have developed a scent and nectar that attracts pollinators.
a: environmental factors.
b:genetic factors
Seeds that fall on fertile soil are more likely to germinate than seeds that fall on rocks.
a: environmental factors.
b:genetic factors

Answer 1

1) Cacti spines — b: genetic factors. (Spines are inherited adaptations that evolved to deter herbivores and reduce water loss.)
2) Maple seed pods (samaras) — b: genetic factors. (Their winged shape is an inherited trait that aids wind dispersal.)
3) Coconuts floating — b: genetic factors. (Buoyant fruit structure is an evolved, heritable trait that enables ocean dispersal.)
4) Flowers with scent and nectar — b: genetic factors. (Production of scent and nectar is an inherited trait that attracts pollinators.)
5) Seeds on fertile soil germinate more — a: environmental factors. (Germination depends on external conditions like soil fertility, moisture, and temperature.)
