Logistic growth:. a. occurs as the result of a "bad luck" event. does not involve exponential growth. b. occurs when a maximum growth rate is reached. c. occurs when a population increases exponentially. d. often occurs in populations living with limited resources.

d. Often occurs in populations living with limited resources

Explanation:

In logistic growth, the growth rate of a population becomes gradually smaller as the population is near to reach the maximum carrying capacity of the environment which is imposed by the limited resources in the environment.

Initially because of available resources, the population grows rapidly but as the resources are limited and they are getting consumed by the growing population, the growth rate slows down further and it gives a S-shaped curve which shows a decrease in growth rate as the population increases.

explanation:

advantage of using stem cells in medical research:

1.       it provides medical benefits in the fields of therapeutic cloning and regenerative medicine.

2. it provides great potential for discovering treatments and cures to a variety of diseases including parkinson disease, spinal cord injuries, diabetes, alzheimer’s disease and many more.

3. limbs and organ could be grown in lab from stem cells and then used in transplant or treat illness.
