Answer:
if the results are efficient in answering the problems raised in the research and if they manage to come to terms with the hypotheses.
Explanation:
As you may know, scientific research must be done through several steps that allow an experiment to be carried out in order to reach conclusions on a certain topic.
In research on the carbon cycle and global warming, it is necessary for the researcher to raise problems and questions about this topic, as well as to raise hypotheses that must be directly related to the results of the experiment. If the result of the experiment is efficient in answering the research problems and questions, in addition to being able to agree with the presented hypotheses, it means that the research has value within the scientific branch in which it fits, in addition to showing that the experiment was done correctly.
 
        
             
        
        
        
Answer:
The correct answer is D) domain
Explanation:
The father of taxonomy is Linnaeus. Taxonomy helps in classify and naming organisms. The modern taxonomy has eight levels of classification. Domain, kingdom, phylum, class, order, family, genus, species.
Domain is the highest level of classification so it is the largest category that would include closely related species. When we go from domain towards species the number of similarities increase and number of organism decrease and vice versa is true when we move from species to domain. So the right answer is domain.
 
        
             
        
        
        
Answer:
Nerve agent
Explanation:
A nerve agent is a chemical in which on exposure to humans affects the functioning of the nervous system. These chemicals are known to disrupt the process by which messages are transferred to the organs from the nerve. This disruption occurs by blocking the activity of acetylcholinesterase, which is responsible for the catabolism of a neurotransmitter, acetylcholine.  
On exposure to a nerve agent, the muscles of the body become paralyzed and early symptoms is production of excess mucous such as in runny nose, pupil constriction and also difficulty in breathing.
 These agents are sometimes used in chemical warfare. Examples include sarin, tabun etc.
