Polar bears appear white, but their fur is not white. However, polar bear fur is transparent with a hollow core. It appears white because it reflects visible light, much like snow. The hair absorbs ultraviolet light from the sun, which in turn provides extra warmth for the skin. Many people do not realize that polar bears have black skin. This is an adaptation that allows maximum warming of the skin when exposed to sunlight.The bear has a short tail and small ears that help reduce heat loss, as well as a relatively small head and long, tapered body to streamline it for swimming.
Sometimes we feel uncertian And unsure of everything, Afraid to make decisions, Dreading what the day will bring- We keep wishing it were possible To dispel all fear and doubt And to understand more readily Just what life is all about- God has given us the answers Which too often go unheeded, But if we search His promises We'll find everything that's needed To lift our faltering spirts And renew our courage, too, For there's absolutely nothing Too much for God to do- For the Lord is our salvation And our strength in every fight, Our redeemer and protector, Our eternal guiding light- He has promised to sustain us, He's our refuge from all harms, And underneath this refuge Are the everlasting arms- So cast your burden on Him, Seek His counsel when distressed, And go to Him for comfort When you're lonely and oppressed- For God is our encouragement In trouble and in trials, And in suffering and in sorrow He will turn our tears to smiles.
