Natural selection can only occur because of a variety in a population. Natural selection refers to environmental factors that affect a population and causes some of the population to have more surviving offspring than others. An example is a giraffe with a longer neck will be more likely to survive and reproduce (as it can gather more food from taller trees)
Dr. Brantz wants to test the part of the brain which is active while lying. For this purpose, he will need to make use of the fMRI (functional magnetic resonance imaging) technique. This technique is used for measuring the brain activity by the means of the detecting changes in the blood flow. The neural activation affects the cerebral blood flow, and this change can be noticed using fMRI.
Hence, the answer is 'fMRI'.
Answer:
Frogs do have gills as well as fully developed lungs which help them to survive both on land and underwater. On the other hand, tadpoles have chubby bodies, long tails and they do not look like a frog eventually in which they turn into. Their lungs take time to develop but once developed they too can live on land.
Explanation:
Answer:
The mechanism by which organisms use oxygen to break down food molecules in order to obtain chemical energy for cell functions is known as cellular respiration. In the absence of oxygen, cells can generate energy by fermenting food, a mechanism known as anaerobic respiration.
