Answer: Their irises are two different colours.

Eye colour is determined by the amount of melanin in a person's eye. Heterochromia iridis is a condition that affects the colour of a person's iris.

Answer: tomatoes and potatoes

The name "Ketchup 'n' Fries" is an allusion to the tomatoes and potatoes that the plant grows. On the vine, sweet cherry tomatoes are grown and found in the ground are the white potatoes. Grafting (the process of physically combining the two halves of different seed types to make one plant) is only possible here because tomatoes and potatoes actually belong to the same nightshade family.

Answer: Shingles

If you've had the pox, the herpes zoster virus remains in your system and makes you susceptible to shingles, which is a very painful rash, appearing mostly around the upper body, sometimes on the forehead, but possible anywhere else. This usually occurs as your body ages, and your immune system is weaker.

It can be difficult to get rid of. There is a form of immunization available.

Question by player banksrj

Answer: Aging

When Leonard Hayflick was growing embryonic cell cultures for vaccine studies in 1961, the scientific community believed that a cell culture, if properly cared for, could live forever. This was because Alexis Carrel had created an "immortal" cell line which had lived for 34 years. Hayflick's work showed that cells have a limited number (between 40 and 60) of times which they will divide before they stop dividing and eventually die.

It was later discovered that the telomeres in cells get slightly smaller with each division and this is what leads to the eventual end of the process.

Answer: Lactic

As you exercise, the body demands energy and so glucose is broken down. This oxidizes to pyruvate (pyruvic acid) and it also produces lactates. The tissues endeavour to remove the lactates but the high demand sees them struggle to keep up, hence the build up.

Answer: Gametes

Although the female egg cell is the largest cell in the body it is relatively small in comparison to the egg cells of animals. For example the egg cell of a goldfish is far larger than that of a human. This is because the human egg cell contains a smaller food store, as the embryo is fed by the placenta soon after becoming embedded in the womb wall.

Question by player AdamM7

Answer: Nitrifying bacteria

The nitrogen found in nitrates can now be taken up by plants via the roots and is used to make proteins.
Saprophytic bacteria are bacteria which secret enzymes onto food. This is known as extracellular digestion.
Denitrifying bacteria convert nitrates into nitrogen gas.
Deaminating bacteria removes ammonia from amino acids formed from the breakdown of dead plant and animal proteins.
