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.
Oxygen, it takes in Carbon Dioxide and releases Oxygen as a waste :)
Central dogma is done by all cells which involves the process of DNA replication, transcription and translation. DNA replication involves making of a new DNA molecule to copy the genetic information and takes place in the nucleus of a cell while Transcription is the formation of a mRNA from DNA molecule by RNA polymerase a process that takes place in the nucleus. Translation involves formation of polypeptides from the messenger RNA which takes place in the cytoplasm (cytosol) of both prokaryotic and eukaryotic cells in an organelle known as ribosomes.
Answer:
Carbon based molecules have 3 main structures which are
straight chain
branched chains
rings
Explanation:
The structure or shape of carbon can be a straight chain, branched chained or in the form of rings. Examples of straight chain carbon includes propane, butane and pentane. Examples of branched chain carbons include members of the alkyl group like methyl and ethyl. Ring shaped carbons form structures in the form of rings like benzene which forms a six carbon ring. All these structures are made and dependent on the ability of carbon molecules to form four covalent bonds. Enormous, complex molecules can be formed by the binding of carbon chains to carbon rings. The carbon based molecules are very important as they are the basic buiilding blocks of life. Many important molecule like the DNA, RNA, lipids are made up of carbon atoms.
