Answer 1

Answer:

circulatory system

The circulatory system distributes nutrients, respiratory gases, metabolic wastes, and hormones throughout the body. In Homarus americanus, the circulatory system is open; that is, the blood (hemolymph) and its circulating cells (hemocytes) directly perfuse all tissues

Answer 2

Answer:

-2

Step-by-step explanation:

P^2+2p+1=0

(P+1)^2=0 p=-1

q^2+2q+1=0

(Q+1)^2=0 q=-1

P^3+q^3= (p+q)(p2-pq+q2)

=-2(1-1+1) = -2
