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 = 
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,

Answer:
The answer is B. It is an endothermic reaction.
Explanation:
Photosynthesis in an endothermic reaction. Endothermic reactions are all those chemical reactions that in their transformation process, in 2 or more different substances, consume Caloric Energy, in which, the products obtained possess higher energy levels, than the initial reagents, since they have taken part of the heat of the environment.
Answer:
Humans' internal body temperature is a great example of homeostasis. When someone is healthy, their body maintains a temperature close to 98.6 degrees Fahrenheit (37 degrees Celsius). Being warm-blooded creatures, humans can increase or decrease temperature internally to keep it at a desirable level.
