why do angiosperms have a waxy covering?to prevent water loss.to prevent sodium loss.to prevent too much sunlight.to prevent attack from predators.algae are ______________ organisms.eukaryoticprokaryoticwhy do some seaweed reproduce sexually?*genetic variation.they will die if they do not reproduce.they cannot produce any other way.spores are too difficult to produce.

Explanation:

• For the first question: Angiosperms have a waxy covering (cuticle) mainly to prevent water loss. Sodium loss is not the main concern related to this covering. While some plants may have adaptations related to light, the waxy covering is not for preventing too much sunlight. And it is not a primary defense against predators.
• For the second question: Algae are eukaryotic organisms. Prokaryotic organisms lack a true nucleus and membrane - bound organelles, which algae have.
• For the third question: Sexual reproduction in some seaweed allows for genetic variation. Organisms do not die if they do not reproduce (asexual reproduction can also occur). They can reproduce in other ways (asexual reproduction like fragmentation etc.). And the difficulty of spore production is not the reason for sexual reproduction.

Answer:

1. To prevent water loss.
2. Eukaryotic.
3. Genetic variation.
