In some breeds of dogs a dominant allele controls the characteristic of barking while training. in these dogs an allele of another independent gene produces erect ears; it is dominant over the allele for drooping ears. suppose a dog breeder wants to produce a pure-breeding strain of droopy-eared barkers, but he knows that the genes for silent-training and erect ears are present in his kennels. how should he proceed

surface modification is a versatile tool and has been widely used in material science and engineering that has significantly facilitated the study and characterization of complex materials. at  matexcel, experienced experts in surface science can offer tailored efforts to meet the specific needs from our clients.

measuring light intensity

light meters can be used to measure light intensity. the meter is held at the soil surface and pointed in the direction of the maximum light intensity, and then the meter is read.

errors can be made when measuring light intensity by accidentally shading the light meter. the reliability of the results can be checked by taking many samples.
