Q1 - All animal species have general characteristics in common. Check all of the characteristics that would apply to members of this kingdom.
Check All That Apply
a- Animal cells possess a cell wall and are quite rigid.
b- Animals have the capacity to move at some point in their life cycle.
c- Most animals undergo sexual reproduction where a small motile sperm cell unites with a larger egg cell to produce a zygote.
d- Not all animals are multicellular.
e- All animals produce diploid spores.
f- All animals are heterotrophs.

Q2- Select the reasons why choanoflagellates are thought to be the closest living relatives to animals. Check all that apply.
Check All That Apply

a- They are simple multicellular organisms similar to simple animals.
b- Molecular comparisons between choanoflagellates and simple animals are similar.
c- They are similar to the cells of simple animals.
d-They have specialized functions as animal cells do

Q3-You are presented with a newly discovered invertebrate species. As you observe it in your lab, you note that the animals shed their skin. Which designation might this lead you to consider?

a- Lophotrochozoa.
b- Ecdysozoa.
c- Choanoflagellates.
d- Echinoderms.

Q4- An organism in your lab has issues with a malformed central nervous system that can be traced all the way back to the embryonic stage. To further investigate this issue, which germ layer would you want to examine closely to get an idea of exactly how the malformation occurred?
a- ectoderm.
b- endoderm.
c- mesoderm.
d- ectoderm and endoderm

Q5- which of the following characteristics are shared by animals and fungi? Check all that apply.
Check All That Apply

a-derived from protists
b- autotrophic
c- absorptive nutrition
d- secrete digestive enzymes
e- cell walls

Answer 1

Q-1. All the characters are apt for animal kingdom except the first one .the animal cell do not possess a rigid cell wall. this is one of the main differentiating features of plants and animals.

Q-2 Chaenoflagellates are not multicellular, they are unicellular simple organisms. All the other statements are true.

Q-3 Ecdysis is the moulting of the cuticle in many invertebrates of the clade Ecdysozoa. Since the cuticle of these animals typically forms a largely inelastic exoskeleton, it is shed during growth and a new, larger covering is formed.

Q-4 Ectoderm is the groups of cells that coalesce early during the embryonic life of all animal. so investigation on ectoderm can give a proper idea of exactly how the malformation has occurred.

Q-5 Fungi and animals are not derived from protist, plants and fungi are derived from protists

both are heterotrophic

absorptive nutrition is the nutrition in which the nutritional substrate (e.g., dead organism or other nonliving organic matter) is directly digested by a variety of enzymes that are excreted by the saprotroph which is seen in fungi and not in animals

they both secrete digestive enzymes

the cell walls are entirely different. Animals don not have cell wall whereas the cell walls of fungi are made up of chitin.
