Answer:
Dragonflies are important for our environment.
Explanation:
Dragon flies belongs to the ancient family of insects. They are found on every parts of the world and have been from around 300 millions years ago. There are more than 5000 different species of them found in different parts of the world. Conserving dragonflies is important as they considered as a valuable environmental indicators.
Dragon flies are found in the areas where water is available and near grasslands. Their life cycle is an example of an incomplete metamorphosis. The dragon flies lays their eggs near the water or in the water. Dragon flies spends most of the life time as a nymph in the water where they turn into an adult and leave the water. The dragon flies rely on the aquatic ecosystems all through their life. Thus dragonflies are an important indicators of the environment and water quality.
Most of the life cycle of the dragon flies depend on the availability of water and its quality. Polluting water and destroying their habitat will result in the decline of the population of the dragon flies.
Three types of axonometric projection<span> are </span>isometric projection, trimetric projection. and dimetric projection.
Fruit flies and humans have very similar genetic structures.
Endothermic change
Explanation:
Enthalpy changes are heat changes accompanying physical and chemical changes. There are two types of enthalpy changes: Endothermic change and exothermic change.
In an endothermic change, heat is absorbed from the surround and hence the surrounding becomes colder at the end of the change.
A change that leaves the reaction colder is an endothermic change.
