it is entirely normal for one testicle to be bigger than the other. Many people find that the right testicle is slightly larger and the left hangs lower. A difference in size is usually nothing to worry about, though it can occasionally indicate a problem.
This is perfectly normal and nothing to worry about. Either side may be slightly larger or hang lower. But be sure to tell a parent (who will let your doctor know) if you have any pain, swelling, or lumps in your testicles.
When a vein in a testicle becomes enlarged, it's called a varicocele. Varicoceles affect up to 15 percent of males. Like varicose veins in your legs, varicoceles may appear bulgy under the skin of your scrotum. They tend to form in the left testicle because the vein on the left side hangs lower.

Answer:
Savanna, is a biome, dominated by grasses. It exhibit dry climatic conditions. This biome receives very little rain fall. The tree population is scanty in this biome. The Savanna biome is found in Australia, Africa, South America and India. The giraffe is an animal that feeds upon leaves, fruits and pods of tall Savanna trees. The giraffe is tall enough to reach the highest branches of the trees.
As, in the given situation, more giraffe feed upon the leaves of the trees closest to the ground until all the leaves or vegetation of the ground and closest to the ground cleans up. Members of the population which have taller neck will be able to thrive leaves growing at the top of the tree canopy. This feature is called as natural selection. This involves the survival of the individuals, which have traits suitable for changing environment. The giraffe which have comparatively long neck will have better advantage for survival than the others in situations of scarcity of food.
