Since the death rate is higher than the birth rate we can assume that it will be negative. 5-15 is -10 for their life. immigration is also lower than the emigration. 2-4 is -2. adding -2 and -10 will give us -12, hope this helps.

The biggest part of our brain, the cerebrum is separated into two halves, the left and the right hemisphere by a deep groove that is called the l<span>ongitudinal fissure or</span> cerebral fissure.
The hemispheres are connected by a bundle of nerve fibers called the corpus callosum in order to enable communication between the two of them, as their communication is necessary for various cognitive functions of the brain.
