a science quesion?

Question

many plants are adapted by nature so that their seeds are dispersed over a great distance. for some plants the seeds are scattered when birds and other animal eat the fruit. because many types of seeds are protected by a coating that is not easily digested, system unharmed. the seeds can be dispersed anywhere the animal travels. other types of plants produce fruit that is covered with sharp barbs that make the fruit difficult, if not impossible, to eat. in these plants the barbs attach themselves to an animal's fur. the animal disperse the seeds as it rubs against the ground or a tree in an effort to get rid of the unwanted hitchhikers.

which of the following factors is most related to the ability of an animal to disperse the seeds of a mulberry tree over a great distance?
1. the speed of the animal while running
2. whether the animal
3. the types of predators that hunt the animal
4. whether the animal migrates in winter
5. the size of the animal

Answer 1

As written, none of the answers really play any part in mulberry distribution. For dispersal of seeds, you need an animal that moves randomly about over a fair distance following consumption of the mulberry fruit/seeds. Birds are great because they eat from one tree, then fly to another, and different, tree to rest, digest, and poop. So the seeds are dispersed from the location of the parent tree. I have many volunteer plants in my yard (mulberry, holly, pyracantha) that arrived this way.

People are the best distributors of mulberry trees; which none of these answers address. Originally from China, mulberries are now worldwide in distribution because people like the taste.

The second best mulberry distributor would:
1) Be present over the season of fruit maturation/ripening.
2) Eat mulberry fruits.
3) Move about in a random manner after consuming mulberries, thereby elimination the seeds in a random but widespread patter. i.e. birds.

The answers:
1) Speed while running. No. Running is generally to escape a predator, and then to a safe refuge. Few animals eat in one location, then run to another to digest/poop.
2) Answer is incomplete.
3) Type of predator. Too nebulous; although I concede that if your main predator is a shark, you are not going to be an efficient mulberry seed distributor.
4) Winter migration. Possibly, but then that animal must find ripe berries with viable seeds at the start of and during migration. However, this was the "most related" criteria, we would see dispersal patterns of narrow banding in the direction of the 'winter' migration .
5) Size of animal. Irrelevant.

Answer 2

Mulberries are eaten by birds that excrete the seeds as they fly. 1. is the closest to being correct.

Answer 3

to prepare dinner in 60 watt micro. = 10min. to prepare dinner in a million watt micr. = 10 x 60 = six hundred to prepare dinner in a hundred watt micr.= six hundred / a hundred = 6 minutes. (answer) six hundred divided by making use of a hundred the respond is 6 minutes.

Answer 4

i can't believe people answer questions like this. what's more important? a few points for a school-level easy-peasy question or the advancement of a child's education?
...
tut-tut

Answer 5

Probably #2: "whether the animal"
Of course, I don't know whether the animal does what, is what, has what, etc.; so I can't be sure.
