Answer 2

Answer:

1) Butterflies have long tubes like proboscis 'cause this long tube help it to suck nectar from deep inside the flowers.

2) Food remains safe at 5 degree Celsius as it prevents the growth of bacteria. This low temperature will prevent bacteria from proliferating, thus preventing the food from spoiling.

3) Body parts varies from person to person, if you are measuring any quantity with your body part, it may not be the same for any one else. Hence it is not safe to measure any quantity with body parts, there are certain units to measure quantity. E.g. The SI System.

4)Dew forms as temperatures drop and objects cool down. If the object becomes cool enough, the air around the object will also cool. Colder air is less able to hold water vapor than warm air. This forces water vapor in the air around cooling objects to condense.
