Answer - B
Fish and reptiles both are ectothermic but fish have gills and reptiles have lungs. Ectothermic organisms do not have an internal mechanism of regulating their body temperature and are dependent on their atmosphere for temperature regulation. Fish, reptiles and invertebrates are examples of ectothermic organisms.
The results of Harlow's experiment were
overwhelming with an average infant monkey spending
17-18 hours per day on the
cloth mother and
less than an hour per day on the wire mother.
Harlow Harlow established the
nature of affection by experimenting on infant monkeys responses to compare the
influence of nursing from the influence of contact comfort. To study this, he compared
a wire mother who provided food, and a cloth mother who did not provide food.
The infant monkeys preferred contact comfort and spent more time with the cloth
mother than the wire mother.
The time that it would take for the population to double is about 7 years.
<h3>What is population?</h3>
The population of an area refers to the number if people that live in that particular area per time. The life expectancy of a population is increased by adequate sanitation. When there is over population in an area, it can lead to malnutrition and decreased food production.
A density dependent factor that affects population growth is disease transmission. The countries with the highest populations in the world do not necessarily have the fastest population growth. One factor that has led to lower fertility rates in Europe and North America is educational opportunity for women.
The occurrence which is not a potential consequence of Earth reaching its global capacity is less spread of disease.
Using;
P= Poe^rt
P = 74,000
Po = 37,000
r = 0.1
Hence;
74,000 = 37,000e^0.1t
74,000/37,000 = e^0.1t
2 = e^0.1t
ln2 = 0.1t
t = ln2/0.1
t = 7 years
