Apea plant that is homozygous for inflated pods and wrinkled seeds is crossed with a plant that is heterozygous for inflated pods and homozygous for round seeds. what is the phenotypic ratio of the offspring?

a)1: 2: 1 1 – inflated pods/wrinkled sees 2 – inflated pods/round seeds 1 – constricted pods/round seeds

b)16: 0 all 16 will have inflated pods and round seeds.

c)3: 1 3 – inflated pods/round seeds 1 – constricted pods/round seeds

d)9: 3: 3: 1 9 – inflated pods/round seeds 3 – inflated pods/wrinkled sees 3 – constricted pods/round seeds 1 – constricted pods/wrinkled seeds

The diagram below represents a marine food web and a process that can harm the human population. each circle represents an organism and the smaller dots inside them represent a toxic substance. what is being represented and how does it harm the population? the diagram represents biological half-life, in which toxins build up in organisms higher up on the food chain, and this can negatively impact humans who consume the organisms and the toxic substance. the diagram represents biomagnification, in which toxins build up in organisms higher up on the food chain, and this can negatively impact humans who consume the organisms and the toxic substance. the diagram represents the process by which different organisms prey upon each other; this can impact the human population by reducing the number of organisms that do not contain the toxin. the diagram represents the way that toxins are metabolized by living organisms, with those at greater trophic levels able to metabolize more efficiently than those at lower levels. this means that those at higher tropic levels are safer for humans to consume compared to the organisms at lower trophic levels.

Which experiment would most likely contain experimental bias ?

Cattle with brown fur and cattle with white fur will produce a reddish roan calf . when examined closely, the calf show about an even number of brown hairs and white hairs that give a reddish appearance when viewed from far away. the fact that both the brown fur allele and the white fur allele are expressed equally in the offspring is an example of
