Answer: diploid

Problem:OPTIONS:
- waterproofness
- webbed feet

Answer the following question given this paragraph: There are about 10,000 living species of birds. Almost all of them can fly. Flying birds are classified in 29 orders. Most species belong to the order of perching birds. A few birds are flightless, such as the ostrich and penguin, but they evolved from a flying ancestor. Q: What important and unusual physical property (for birds) do ostriches and penguins share? A:
****
A: flightlessness

Answer the following question given this paragraph: Unlike the sponges which evolved prior to cnidarians, the cnidarians are made up of true tissues. The inside of a cnidarian is called the gastrovascular cavity , a large space that helps the organism digest and move nutrients around the body. The cnidarians also have nerve tissue organized into a net-like structure, known as a nerve-net, with connected nerve cells dispersed throughout the body. Cnidarians do not have true organs, however. Q: What is a large space that helps the organism digest & move nutrients around the cnidarian body? A:
OPTIONS:
- thorax
- abdominal wall
- vacuole
- gastrovascular cavity
gastrovascular cavity

Answer the following question given this paragraph: Regardless of what gravity is a force between masses or the result of curves in space and time the effects of gravity on motion are well known. You already know that gravity causes objects to fall down to the ground. Gravity affects the motion of objects in other ways as well. Q: What is the force that causes objects to fall down to the ground? A:
OPTIONS:
- velocity
- pull
- motion
- gravity

Answer: gravity

Question: Answer the following question given this paragraph: Acetylene is an interesting example of a molecule with two central atoms, which are both C atoms. Polyatomic ions are bonded together with covalent bonds. Because they are ions, however, they participate in ionic bonding with other ions. So both major types of bonding can occur at the same time. Q: What is an interesting example of a molecule with two central atoms, which are both c atoms? A:
OPTIONS:
- chloride
- water
- sulfur
- acetylene
Answer: acetylene

input: OPTIONS:
- life extinctions
- earthquakes
- starvations
- mass extinctions Now, answer this question: Answer the following question given this paragraph: Describe at least two major changes to the animal phylogenetic tree that have come about due to molecular or genetic findings. How is it that morphological data alone might lead scientists to group animals into erroneous evolutionary relationships? 26. Briefly describe at least two theories that attempt to explain the cause of the Cambrian explosion. How is it that most, if not all, of the extant animal phyla today evolved during the Cambrian period if so many massive extinction events have taken place since then?. Q: Most, if not all, of the extant animal phyla today evolved during the cambrian period, yet many of what devastating events have taken place since then? A:
A:
output:
mass extinctions
