The missing options for this question are as follows:
1. Only positive outcomes can result from new technology in science.
2. Scientists should conduct long-term studies of DNA technology to determine the consequences.
3. There is no connection because they are different technologies.
4. Scientists should not use new technology; they should use the methods for pest control that are already available.
Answer- <u>Option 2, Scientists should conduct long-term studies of DNA technology to determine the consequences</u>.
Explanation: Pesticides are chemicals which are harmful for humans because they can be consumed through the crops, if the crops are not washed properly. Also, its harmful for farmers as well, who use them. Use of DNA technology can help farmers get the plants which are pest-resistant. The change in features, or production of some biomolecules in plants can resist them from being eaten up by pests. But this should be studied and given some time to see the results. Side effects of consuming these modified crops should be studied properly, because they should be harmless to humans and animals consuming them.
"Disirable" is the correct answer
It is the nucleus because it stores your DNA
The point of the experiment has been foiled by the choice to hand water one group and use sprinklers on the other. Whether talking to the plant or not did anything can't be proven because of this. If the student were to try to publish this experiment and the outcomes. Critics would be able to use the unequal treatment in water supply as a reason to discredit his/her experiment and dismiss the claims. When performing an experiment like this it is very important to treat each side as equal as possible.
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.
