<span>The answer is Haploid spores germinate to give rise to protonema, which later develops into a sporophyte.</span>

Inga [223]

Answer:

I would write "terrestrial/lives on land during all life stages" between the frog and pigeon branches.

Explanation:

Jaw evolution has started with fish, so i'd place that before the perch, evolution of four limbs is next and I would plate it between the perch and the frog. Evolution of an egg has ensured that organisms remain terrestrial during all stages of life and don't need to rely on water to lay their eggs. So I would place that between the frog and the pigeon. True mammary glands and true hair, as we know it formed on mammals so i'd place that between the pigeon and the rats (although synapsids evolved similar structures long before birds even existed). And lastly, I would place "walking on two legs" between rats and human branches. Because our ancestors evolved bipedalism relatively late.

Sea urchins tend to have great camouflage because they sometimes carry what two animals on there shells?​
Fudgin [204]

Sea urchins tend to have great camouflage because they sometimes carry algae and rocks on their shells.

<h3>What is camouflage?</h3>

Camouflage is a defense mechanism used by certain organisms to avoid predation or surprisingly attack their prey.

Different animals possess different camouflage mechanisms. For example;

  • Chameleons change their color to that of their immediate environment
  • Certain snakes hide in vegetations that blend with their skin color.

However, sea urchins are aquatic animals that tend to have great camouflage because they sometimes carry algae and rocks on their shells.
