the population goes down
Explanation:
Large algal beds die, depriving marine iguanas, turtles and many fish of their staple diet. Once weakened, strong swells and sea urchins break apart complex coral habitats that sustain diverse species changing the environment.
The correct answer is: d. it contains many light-sensing columns called ommatidia
Ommatidia are units that form compound eyes of arthropods such as insects, crustaceans and millipedes (these are invertebrates) and make them very sensitive to motion. Ommatidia are composed of photoreceptor cells (visual detection) surrounded by support cells and pigment cells.
The eyes of vertebrates are more complex showing that progressive improvements in the structure of the eye occurred during the evolution.
Answer:
The correct answer is 4. The presence of a polar or charged head group attached to the phosphate.
Explanation:
Lipids have a hydrophilic head and a hydrophobic tail. This allows them to form structures where the tails are hidden on the inside, and the heads interact with the water molecules. This conformation is the best energetically and allows the lipids to interact with aqueous environments.
