Both are similar ideas. Darwin's theory says that the next generations are made by small changes in the present ones. Little by little, future generations will evolve slowly.
Lamarcks theory says that the changes made in present generations will be passed down to future ones. The evolution would happen faster with Lamarcks theory then with Darwin's theory.

LiRa [457]

Answer:

$\frac{dN}{dt} =$ 14130

Explanation:

Logistic growth is a measure of continuous growth of a population of individuals in such an environment where the resources are limited. Such type of growth pattern has a characteristic growth curve which is S-shaped or sigmoidal.

The equation for logistic growth is as follows -

Change in population size = $\frac {dN}{dt} = rN(K- \frac {N}{K})$

Where,

N = size of population

r = intrinsic rate of increase

K = carrying capacity

The values of r, N and K are given in the question as 12, 30 and 40 respectively.

So,

$\frac{dN}{dt} = 12 \times 30(40 - \frac{30}{40}) = 14130$
