<span>To prove his Theory of Evolution. After studying the different species of finches he found the Galapagos Islands, Darwin focused on breeding pigeons by selecting specific traits of different individuals (this is mainly a method through which different kinds of dog breeds came about). On the basis of these studies Darwin concluded that natural selection and artificial selection acted roughly in the same way. Darwin's decision to enforce a certain trait represented, in a sense, the selective pressure which is present in a natural environment (the law of the fittest).<span>

Answer:D
Explanation: The pulmonary air sacs of birds only permit a unidirectional flow of air through the lungs. Unidirectional flow means that air is inhale and exhale through one trachea alternatively. This means the bird lungs only receive largely fresh air which has a high oxygen content during inhalation and do not receive fresh during exhalation. While air flow bidirectional in mammals.
External fertilization
In this type of fertilization, the female lays numerous eggs and they are fertilized externally by the males that ‘pours’ its sperm on the eggs.
Explanation:
While laying of many eggs gives an increased chance of diversity in the population, many offspring don't make it to maturity due to low parent care. There is, therefore, more wastage of reproductive energy compared to internal fertilization.
On the other hand, in internal fertilization, the egg is fertilized inside of the female and develops into a young organism before it is birthed. Even though there are fewer offspring produced, the more parental care they receive gives them an increased chance of survival. There is also low reproductive energy loss.
