Answer:
A fruit fly of 75h AEL is at larval stage.
Explanation:
The development of a Drosophilia starts from egg to larva to pupa then to adult. The full development at 25 degrees Celsius takes between 8.5 to 10 days. The higher the temperature, the faster the development of the Drosophilia.
The eggs hatch after 12-15 hours into larval stage which then lasts for 3-4 days(72-96 hours) then the pupal stage which also lasts for 3-4 days before it becomes a full adult.
Thus, 72 hours after egg laying would still be in larval stage. The larval stage ends after at leas 90 hours after egg laying.
Answer:
A food chain shows you how one organism eats another and transfers its energy.
Explanation:
For example, a zebra eats grass, and the zebra is eaten by the lion.
C.Directly away from the Sun.
Explanation:
The umbra of Earth’s shadow is about 1.4 million km (860,000 mi) long and points directly away from the sun. A giant screen placed in the shadow at the average distance of the moon would reveal a dark umbra about 9000 km (5700 mi) in diameter, and the faint outer edges of the penumbra would mark a circle about 16,000 km (10,000 mi) in diameter. For comparison, the moon’s diameter is only 3476 km (2160 mi). Consequently, when the moon’s orbit carries it through the umbra, it has plenty of room to become completely immersed in shadow.
D: Heavy rain, cooler weather and clear days
