Answer:
Their winter habitat has no bearing on their degree of reproductive isolation.
Explanation:
The two species of sparrows breed only during spring and summer and it has been given that during this time the species live separate from each other. Hence they do not breed with each other.
It is in winter that they live together but this season is not the breeding season. They only feed and prepare for the upcoming breeding season during this time hence the winter habitat has no effect or bearing on their degree of reproductive isolation.
Reproductive isolation only comes into play during summer and spring where they show prezygotic isolating mechanism. They live far from each other thus show habitat isolation due to which they do not mate with each other.
A zygote is the first cell that results when an egg is fertilized by a sperm.

Answer: 50 kilometers
Explanation:
From the question, we are informed that the Pacific plate is moving at a speed of 5 centimeters per year. The number of kilometers that the Pacific plate will travel in 1 million years would be calculated as:
= 5 × 1,000,000
= 5,000,000 centimeters
Since 100000 centimeters = 1 kilometer, we would convert 5,000,000 centimeters to kilometers. This will be:
= 5,000,000 / 100,000
= 50 kilometers
