Chicken Vs Egg
watch the video of which one came first, the chicken or the egg, to find out the answer to this problem.
Fish embryo development
Fish embryo development. a section through a fish embryo during the early stages development. The cells here are known as blastomeres. Blastomeres are produced through cleavage, a type of cell division, of the ovum after fertilisation. Many blastomeres make up a hollow sphere of cells known as the blastula (seen here).
Used toothbrush under electron microscope

Used
toothbrush bristle. a bristle from a used toothbrush. It is covered in
dental plaque. Plaque consists of a film of bacteria embedded in a
glycoprotein matrix. Plaque is the main cause of tooth decay. The
bacteria feed on sugars in food, producing acid as a waste product. This
acid corrodes the teeth's enamel coating, resulting in dental caries. A
build-up of dental plaque can also lead to inflamed and infected gums.
Bladder adhesions

Bladder adhesions. Gross specimen of a urinary bladder with adhesions (string-like) across its inner surface. Adhesions are growths of fibrous (scar) connective tissue formed as a response to tissue trauma. Causes include surgery and infection.
Female Reproductive System Anatomy
Female reproductive anatomy. Artwork of an anterior (frontal) view of the position of the female reproductive organs in relation to the bones of the pelvic region, the blood vessels, and the nerves.The iliac blood vessels branch out from the abdominal ends of the aorta and vena cava, with smaller uterine and pelvic blood vessels also shown. Nerves branch out from the spinal cord. The hip joints are at left and right.
Blood Vessel Formation
Ringworm Infection
Ringworm infection. Close-up of the interspace between the toes of a patient infected with ringworm (dermatophytosis), showing the white macerated skin. Ringworm is caused by infection with a parasitic dermatophyte fungus that feeds on the keratin in the outer layer of skin hair and nails.

Protect Your DNA
As we age, the ends of our chromosomes -- called telomeres -- become shorter. This makes people more vulnerable to disease. You might think there's nothing you can do, but new research suggests otherwise. In a pilot study, lifestyle changes boosted an enzyme that increases telomere length.
