Answer:
because protein molecules are very large in molar masses
Answer:
paleoclimatologists use different sources of information from fossils in order to record past climate and environmental conditions (for example, tree rings or skeletons of coral reefs)
Explanation:
Paleoclimatology is the discipline that studies ancient climate and environmental conditions. Paleoclimatologists are researchers that analyze different sources of evidence to obtain accurate records of past climate conditions. In this regard, the fossil record has proven to be a useful tool to obtain such information. For example, the rings of fossilized trees are usually wider during warm and wet years, while these rings become thinner during cold and dry years. Moreover, geochemical records from the skeletons of fossil corals (composed of calcium carbonate) are good indicators of past climate conditions because coral growth is sensitive to small fluctuations in water temperature. Paleoclimatologists also use non-biological climate indicators (e.g., sediments and ice sheets) to reconstruct past climate and environmental conditions.
Answer: I think its carbon!
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.'
