Humans impact the physical environment in many ways overpopulation, pollution, burning fossil fuels, and deforestation. Changes like these have triggered climate change, soil erosion, poor air quality, and undrinkable water.
Sorry but three struggling
Water molecules bond to each other in a covalent bond where they stay connected. They also have poles like a magnet, making it a polar molecule.
If water is no longer polar the surface tension would lower to the point where ice can no longer float, the water would freeze, cooling the climate considerably.
The sentence "Lightening that strikes the dry forests can cause forest fires" is restrictive: no commas needed. The correct answer is A.

The brain has 3 major parts - cerebrum, cerebrum, brain stem. The brainstem is also divisible into three parts - medulla oblongata, pons, midbrain. The brain stem concerns with breathing, digestion, circulation.
The cerebrum is present between the cerebrum and midbrain. It carries motor information. It consists of the thalamus, hypothalamus. The hypothalamus function is the maintenance of homeostasis. The pituitary gland is present in the hypothalamus region.
The cerebrum has different lobes - frontal lobe, parietal lobe, occipital lobe, temporal lobe. These lobes are meant for sense i.e. vision, auditory, smell, and taste, etc.
The cerebrum is also divisible into the right and left hemispheres.
