Answer: Antenna
Explanation:
The morphogenesis is a process by which the egg get transformed into a matured adult insect. The egg transform into several transitional stages such as embryo, larva, pupa and finally to adult insect.
The fruit flies undergoes three development stages during morphogenesis these includes the egg, larvae and pupa. The fruit flies can develop into adult within 1-2 weeks at room temperature. The egg as well as larval stages takes a span of eight days whereas the pupal stage takes six days for development.
The embryo enclosed inside the egg exhibit three important parts the head, thorax and abdomen the antenna is the structure which develop in adult flies.
The correct answer is (2) - Stratosphere.
Ozone is found in the stratosphere , a layer beginning between 6 and 10 miles above the earth's surface and extends upward to about 30 mile above the surface of he earth.
The ozone that is found in the stratosphere absorbs most of he harmful ultraviolet sunlight and is thus called the "good ozone"
Ozone is also found in the lower region of the atmosphere known as the troposphere. But the ozone here strongly reacts with molecules causing toxicity in plants. The ozone is therefore termed as "bad ozone."
