Archaea and bacteria were kept together in fact they were classified as bacteria. They have some similarities in common.

  • They were morphologically similar.
  • They both were prokaryotes which means they were not compartmentalized.
  • Archaea and bacteria had similar kind of eating habits.
  • They both used similar ways of respiration which means they both were able to respire using oxygen and other substances too.

Degger [83]

<u>Answer:</u>    A. Carbohydrate

<em>When green sea turtles eat algae they are getting carbohydrates from it. </em>

<u>Explanation:</u>

Different sea turtles have different diets. Some are omnivores while some are herbivores. Green sea turtles belong to the group of herbivorous sea turtles.  

<em>The diet of hatchlings is different from that of the adults. Hatchlings are omnivorous and feed on mollusks and crustaceans.</em> The adult sea turtles have to scrape off algae from rock surfaces and hence has a beak shaped like the teeth of a saw.

Which do you think would adapt and survive overtime to a mass extinction? A starfish or an eel?
Harlamova29_29 [7]

Answer:

Starfish

Explanation:

This is an opinion questions, so there really isn't a right or wrong answer.  You could just as easily choose Eel.  Your task is to pick one and defend your reasoning.

I chose starfish because starfish have a long history of demonstrated adaptability to a wide variety of conditions.  Their armored skin protects them from a variety of predators, as does the poison that many of them contain.  They have the ability to regrow limbs, and even regrow entire starfish from certain body parts.  When it comes time to breed, starfish meet together in groups.  Each female releases a few million eggs from the gonads in each of her arms.  Each male then releases billions of sperm from each gonad in each of his arms, thus covering the eggs with sperm to fertilize them.
