bija089 [108]

Answer:

b. Engineers should consider how much pollution their devices create because of how human health is affected.

Explanation:

Anthropocentrism, is a worldview that argues that humans are more important and significant that any other entities or species in the world. This view point argues that humans possess greater intrinsic values compared to other species; this viewpoint sees humans as superiors while other entities are inferior to them and hence can be used by humans for their own benefit.

Therefore the anthropocentric viewpoint as it relates to environmental ethics implies that engineers should consider how much pollution their devices create because of how human health is affected.

How can the random distribution of alleles result in a predictable ratio?
levacccp [35]
Phenotypically and genotypically there are only two different ratios. If you think of a Punett square... 

<span>You could say that a pea plant with the trait for the dominant color green (G) could also carry the recessive trait for yellow (g). So let's say you mate a dominant green, (Gg) with another dominant green, (Gg). You would get 1 (GG), 2 (Gg) and 2 (gg). </span>

<span>Phenotypically (as in physical traitwise), the ratio is 3:1 because you have 3 green colored peas and one yellow. </span>

<span>Genotypically (as in traitwise), the ratio is 1:2:1, because you have 1 (GG), 2 (Gg) and 1 (gg). </span>

<span>So although it's random, for any specific trait there are only 4 different outcomes.</span>

A zebra mussel is discovered in a lake in Pennsylvania for the first time. Why would this make an ecologist worried?
Elena L [17]

Answer:

D

Explanation:

Zebra mussels can be a nuisance in novel ecosystems. When introduced in a non-native ecosystem with no natural predators, they reproduce rapidly displacing native mussels. Zebra mussels take up much of the algar that feeds the other native species hence starving them to death and causing their numbers to plummet. In addition, they attach to the other mussels and clog up power plants, that use the local water, water intakes.
