In humans, eye color is controlled by three genes. bey1, bey2, and gey1. The presence of the dominant Bey1 produces brown eyes. In the absence of Bey1, i. e., bey1/bey1, expression of the other genes is seen bey2 encodes brown and blue; brown is dominant gey encodes green and blue; green is dominant. Predict the (genotypic and phenotypic) eye color for offspring from the following parents: bey1/bey1 bey2/bey2 gey/gey x bey1/bey1 Bey2/bey2 Gey/gey
2. Optional. Bey1/Bey1 bey2/bey2 gey/geyx Bey1/Bey1 Bey2/bey2 Gey/gey

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.

the nitrogen cycle provides nitrogen to the ecosystem from the atmosphere, ground and oceans. nitrogen is an important component of complex molecules such as amino acids and nucleotides, which lead to the creation of proteins and dna, the building blocks of all life. plants absorb nitrogen in the form of ammonium, nitrate ion and, on rare occasions, as amino acids. animals receive nitrogen necessary for biological processes from feeding on living or dead organic matter.
