Use the following information to answer the question. The phylum Cycliophora was discovered in 1995. They are tiny organisms that live in large numbers on the outsides of the mouthparts and appendages of lobsters. The feeding stage permanently attaches to the lobster via an adhesive disk and collects scraps of food from its host's feeding by capturing the scraps in a current created by a ring of cilia. The body is saclike and has a U-shaped intestine that brings the an,,,us close to the mouth. Cycliophorans are coelomates, do not molt (though their host does), and their embryos undergo spiral cleavage. Which of these, if discovered among cycliophorans, would cause the most confusion concerning our current understanding of cycliophoran taxonomy?
|
if the organisms show little apparent cephalization |
||
|
if embryos are diploblastic |
||
|
if the ciliated feeding ring is a lophophore |
||
|
if the body cavity is actually a pseudocoelom |

a.120
b.between 120 and 125
c.125
d.above 125
ii.supposez the non-institutionalized population over age 15 is 20 million, 10 million of whome are female, the labour force is 16 million, 6 million of whome are female, and the number of people employed is 15 million, 5.5 million of whome are female. the female participation rate is:
a. 10/20
b. 6/16
c. 5.5/15
d. 6/10
iii.consider an economy in which the current level of income is $700b, the multiplier is 3, the marginal tax rate is 20%, and the current budget deficit is $20b. suppose the government increases the spending to increase GDP to $715b, the budget dificit becomes:
a. less than or equal to $20b
b. more than $20b but not more than $23b

Many organizations have been accused of using suppliers which engage in unsafe labor practices (i.e., Apple procuring tin) or unsafe components or methods (i.e., lead paint on toys made for Mattel). State your position regarding the degree to which “end use organizations” (i.e, Apple, Mattel, Walmart) should be responsible for the problems their suppliers create. Then explain WHY you take this position – i.e., justify your position.
