Answer:
The new volume of the gas at stp is 367mL
Explanation:
Using general gas equation:
P1V1 / T1 = P2V2/ T2
P1 = 780mmHg
V1 = 350mL = 0.000350L
T1 = 24.2°C = 24.2 + 243= 297.2K
At stp that is standard temperature and pressure, P2 = 760mmHg
T2 = 273K
V2 = ?
To calculate V2 :
V2 = P1V1T2 / P2T1
V2 = 780 * 0.000350 * 273 / 760 * 297.2
V2 = 74.529 / 203072
V2 = 0.000367L
V2 = 367mL
Answer:
Hunting is all i can think of
I am asamulating b but it could be a or c.
Answer:
The correct option is <em>B. All ecosystems contain symbiotic relationships.</em>
Explanation:
Symbiotic relationship can be described as a relationship between the organisms of two species.

Hence, option B is correct.
Other options like Option A is false because the desert ecosystem does has symbiotic relationships. For example, the Gobi woodpecker lives on a cactus in a desert. In return it eats the insects and other parasites which harm the cactus.
