Answer:
B. That some fraternal twins resemble each other greatly while others look quite dissimilar highlights an interesting and often overlooked feature of fraternal-twin pairs, namely that they vary considerably
Explanation:
Fraternal twins are the most common type of twins in the world, about 70% of the total twin population. They may also be called biviteline or dizygotic. They are characterized by being developed from different eggs and sperm, even during the same gestation period. Fraternal twins do not share genetic information, so they do not become identical. In fact, they can be as different from each other as non-twin siblings, including even blood groups.
With this we can conclude that some fraternal twins resemble each other greatly while others look quite dissimilar highlights an interesting and often overlooked feature of fraternal-twin pairs, namely that they vary considerably

In adults aged 18–64, physical activity includes leisure time physical activity (for example: walking, dancing, gardening, hiking, swimming), transportation (e.g. walking or cycling), occupational (i.e. work), household chores, play, games, sports or planned exercise, in the context of daily, family, and community activities. In order to improve cardiorespiratory and muscular fitness, bone health, reduce the risk of NCDs and depression:
Adults aged 18–64 should do at least 150 minutes of moderate-intensity aerobic physical activity throughout the week or do at least 75 minutes of vigorous-intensity aerobic physical activity throughout the week or an equivalent combination of moderate- and vigorous-intensity activity.
Aerobic activity should be performed in bouts of at least 10 minutes duration.
For additional health benefits, adults should increase their moderate-intensity aerobic physical activity to 300 minutes per week, or engage in 150 minutes of vigorous-intensity aerobic physical activity per week, or an equivalent combination of moderate- and vigorous-intensity activity.
Muscle-strengthening activities should be done involving major muscle groups on 2 or more days a week.
