3

Water flow is an important aspect of any sponge's life. The water flows in through the ____________, and out through the ____________. 

Ostia , Osculum 

4

Check two boxes: Identify the organism, and the part that is colored brown.

Uterus Clonorchis

5

6

The organism above contains stinging cells that allows it to catch prey and that also give the phylum its name. What are these cells called?

Cnidocytes

7

name the parts 

A flagellum 

B food particles 

C Choanocyte

D Amoebocyte

E Collar

8

name the flagellated cells that line the sponge 

Choanocytes

10

What is dominance to the microevolutionary process?

 

A rare dominant allele initially spreads faster than a rare recessive allele (for the same selection coefficient in each scenario).

12

What is/are function(s) of the structure indicated by the arrow?

feeding 

15

What is this unique stinging cell called that is possessed by Cnidarians?

cnidocyte

16

The body plan of cnidarians is composed of two cell layers, the epidermis (from ectoderm) and the gastrodermis (from endoderm). Therefore, these simple animals are triploblastic and have well developed organ systems. 

false

18

the relative abundance of the differnt species in an area 

species evenness

19

species diversity 

a measurement that weights each species by its abundance, accumulated with greater numbers of species
