Among the ones listed above, the statement that best describes the way that the periodic table is arranged is "<span>The nonmetals are grouped together, which the exception of hydrogen.</span>" It can be seen that all of the nonmetals are placed on the far right of the periodic table except for hydrogen. They do not belong in a single column and are separated from the metals by the metalloids. Moreover, the elements are placed in the periodic table in increasing atomic number.
Answer:
Catalysts lower the activation energy for reactions. The lower the activation energy for a reaction, the faster the rate. Thus enzymes speed up reactions by lowering activation energy. Many enzymes change shape when substrates bind.
Explanation:
DNA contains the instructions for an needed for an organism to develop, survive, and reproduce.
There are various imaging techniques in collecting information about the brain and its adjacent structures. To enumerate, there are the cranial ultrasound (for children with cranial sutures that are not closed yet), cranial CT-scan, cranial MRI, brain PET scan, and cranial functional MRI. Only the brain PET scan and cranial functional MRI can collect information about the brain function by detecting fluorodeoxyglucose (FDG) in the brain as this lights up in functional areas of the brain in PET scan; and by detecting brain activity through changes in blood flow in cranial functional MRI.
<em>While it is not an imaging technique, electroencephalogram or EEG can detect brain function.</em>
