Scientists use labs to Design and Carry out experiments.
Ans.
Genetically modified grasses are produced by using genetic engineering techniques, which contain genes for drought and disease resistance. Due to those genes, these grass varieties have higher chances to survive in stress condition and they spread with a fast and tremendous rate.
Most of the genetically modified grass varieties are still not approved by government, because 'these grass species may act as uncontrolled invasive species and cause harm to other useful plant species as they can spread fast and hard to wipe out due to resistance against stress conditions.'
Answer:
On the basis of physical traits.
Explanation:
Newer classification systems classify organisms on the basis of physical traits of an organism. All modern classification systems gets their concept and help from Linnaean classification system. In these new classification systems, those organisms that have similar characteristics are placed in one group because they evolve from the same ancestor or having common ancestry. These changes occurs in the organisms with the passage of time that helps organisms to survive in that environment.
