fan and medal

Answer 1

Your answer is correct. Phyla contain Classes which contain Orders which contain Families which contain Genera and then species, so the Family would have the fewest number of species in your list above.

This is because there could be several Families (and their species) in each Order and several Orders in each Class, etc.

Answer 2

thank you

Answer 3

Which traits are characteristic of both single-celled and multicellular organisms?



Choose all answers that are correct.



A.


contain organs that help them survive


B.


have metabolism


C.


can reproduce a whole colony in a matter of hours


D.


have ability to reproduce


my answers : C & D

Answer 4

D is correct, but I'd choose B as the other answer. All living things metabolize.
I don't know of any multicellular organisms that can produce a colony within hours, but a lot of unicellular specis certainly can.

Answer 5

Which traits are characteristic of multicellular organisms?



Choose all answers that are correct.



A.


can reproduce a whole colony in a matter of hours


B.


contain organs that help it survive


C.


can grow larger by making new cells


D.


divide in two to reproduce

my answers :A & D

Answer 6

I know of multicellular organisms that can do everything except A. I imagine your instructor is looking for B and C, but I do know of some multicellular organisms that also can do D. There are anemones that do that and possibly some worms.

Answer 7

Anemone fission

Answer 10

Which traits are characteristic of single-celled organisms?



Choose all answers that are correct.



A.


contain organs that help them survive


B.


divide in two to reproduce


C.


cannot carry out their own life processes


D.


able to replicate themselves in a small time frame


my answers : C & D

Answer 11

They can carry out all their own life processes (it's viruses that cannot and they are not cellular).
Unicellular organisms can divide in two to reproduce.

Answer 12

A & B

Answer 13

Just in case your instructor has a problem with multicellular organisms dividing in half, here's another example

A.
Species


B.
Felis


C.
Mammalia


D.
Carnivora

i said B

Answer 27

@jherrera57

Answer 28

The most specific classification would be the species Felis sylvestris, but your answer choice doesn't actually list the species name.
Species is the most specific in the list.
This is kind of tricky. It depends on what your teacher wants.
Species is the most specific, but the cat species isn't listed, so I guess the actual genus name of Felis is probably correct.

Answer 29

i think the correct answer is D.Carinvora
just saying

Answer 30

if u look @ the list u can see that the cat is listed under Order Carnivora
that's why i think it's D

Answer 31

A carnivore could be a dog or a bear. That's not specific to a cat. Genus Felis is a cat genus so that is more specific. The species name is the most specific. I don't know if you r teacher wants species or Felis, but it is one or the other.

Answer 32

The question asked for the most specific classification. The most specific classification on the image is Species Felis sylvestris
