Albinism results from inheritance of recessive gene alleles and is known to affect all vertebrates, including humans.here are two different forms of albinism: a partial lack of the melanin is known as hypomelanism, or hypomelanosis, and the total absence of melanin is known as amelanism or amelanosis.
The Photonâs Go-Splat World. The photon lives in a âgo-splatâ world. The clock of a photon completely stops the instant it is emitted and stays stopped throughout its journey. The distance traveled by a photon becomes zero as compared to the distance measured by the stationary observer.instein gave us some tools to work with to describe the various space-time relativistic changes as shown in Figure 1. There is a mass equation also, but the mass increase is not a factor here, since we know that the photon has no rest mass.
The body clock, or circadian clock, is an internal clock that keeps track of time. Circadian comes from circa-diem meaning around a day. So in a mouse for example it is about 23.5 hours and for a human its about 24.5 hours. If you are kept in constant darkness your body will still work to around a 24-hour cycle. It is not just being driven by light and dark. It is an intracellular clock so if you look in individual cells they are all able to keep time as well. If you put cells in a dish they will show 24-hour changes in gene expression.
