Answer:
Both cones and flowers produce seeds and are used for reproduction. ... The male cones release pollen which is carried by the wind to a female cone. A pollen tube is formed and pollen is transferred to fertilize the female cone's egg
1.26 mole
Explanation:
Using ideal gas law
PV=nRT
R= 0.08206
T=273+87=360
1.2×31=n×0.08206×360
37.2 =n × 29.54
n= 1.26 mole
