Mrac [35]4 years ago
6 0

Answer:

Germination

Explanation:

The sporophyte reproduces asexually through spore formation. The spores are  formed in a capsule. Once the spores are mature the capsule breaks releasing them. The spores germinate to form a gametophyte. The gametophyte produces gametes that fertilize forming an embryo. The embryo develops into a sporophyte that remain attached to the gametophyte for nourishment.

ale4655 [162]

Answer:

P=750 e^{0.00963t}

The population size would be 753,190 after 30 days

Explanation:

Since, the population growth function is,

P = P_0 e^{rt}

According to the question,

if t = 0, P = 750,

\implies 750 = P_0 e^0\implies P_0 = 750

Also, if t = 72, P = 1500,

\implies 1500 = P_0 e^{72r}\implies 1500 = 750 e^{72r}\implies 2 = e^{72r}\implies \ln 2 = 72r\implies r = \frac{\ln 2}{72}\approx 0.00963

Hence, the required function would be,

P=750 e^{0.00963t}

If t = 720 hours  ( 30 days = 720 hours ),

Then, the population after 30 days would be,

P=750 e^{0.00963\times 720}=750 e^{6.912}=753190.30695\approx 753190
