Answer:
<h2>C-A-B</h2>
Explanation:
Given
As given: A and B are 30 map unit apart
A and C are 15 map unit apart
B and C are 45 map unit apart
So the sequence of genes : according to the map unit distance is:
C-A-B
C-15-A-30-B
C-A=15
A-B=30
C-B= 45.
correct order of genes is C-A-B

D. A duck flies to another pond.
The above sentence is an example of emigration. Emigration refers to moving from one area to another for a long or permanent period. In this instance, a duck is leaving the pond it originally resided in (along a population other ducks) in order to reside in another pond. Therefore, it can be said that the duck "emigrated".
Air mass is a large body of air that exhibits uniform temperature and moisture characteristics and helps to determine the weather within an area. Warm air masses tend to form over oceans in warm-temperature regions of the tropics and sub-tropics, while cold air masses tend to form over land in cold-weather regions nearer the poles. The cold air masses that form at the poles move toward the equator, while the warm air masses that form at the equator move toward the poles. These air masses can undergo gradual, but significant, changes as they pass over warmer or colder land surfaces encountering different types of air. These boundary lines are called front.
