This "cellular automata machine" allowed an explosion of alife research among scientists who could not ...

Cancer

... other beneficial interventions, e.g., exercise. Contrary to expectation, randomized trials found no benefit of beta-carotene supplementation in reducing lung cancer incidence and mortality; risk of lung cancer was statistically significantly increased in smokers in the beta-carotene arms of 2 of the ...

Chromosomal crossover

... chromosomes may be expected to cross over three or four times during meiosis. This aids evolution by increasing independent assortment, and reducing the genetic linkage between genes on the same chromosome. The physical basis of crossing over was first demonstrated by Harriet Creighton and ...

Light-dependent reaction

... pigments is used to drive a transfer of electrons and hydrogen from water (or some other donor molecule) to an acceptor called NADP + , reducing it to the form of NADPH by adding a pair of electrons and a single proton (hydrogen nucleus). The water or some other donor molecule is split in the ...

Nutrition

Signal transduction

... tissue. Some hormones can be modified by the target cell so they no longer trigger the hormone receptor (or at least, not the same one), effectively reducing the amount of available hormone. The nuclear receptors that were activated by the hormones attach at the DNA at receptor-specific Hormone ...

Twin

... (or the same amnion and placenta) can cause complications in pregnancy. For example, the umbilical cords of monoamniotic twins can become entangled, reducing or interrupting the blood supply to the developing fetus. Monochorionic twins, sharing one placenta, usually also share the placental blood supply. ...

X chromosome
