The lowest trophic level in an ecosystem____. 1) has the lowest quantity of stored energy 2) has the greatest biomass 3) is made
DochEvi [55]
In describing the energy transfer of trophic levels, energy is lost as we move up from a lower level to a higher level. This is because energy is used when for example a primary consumer does body processes before it is eaten by another consumer.  hence the lowest trophic level belongs to those which <span>2) has the greatest biomass</span>

A widows Peak is dominant over straight hairline the genotypes of The Offspring are WW, Ww, ww and ww. What are the phenotypes o
anastassius [24]

Phenotypes are the physical characteristics that result from the genotype, which is the genetic makeup of the organism. In this case, either straight hairline or Widow's peak will be the phenotype, as they are the physical characteristics being discussed.

The questions states that a Widow's peak is dominant over straight hairline. So we are going to assume that the Widow's peak allele is W (dominant), and the straight hairline allele is w (recessive).

A dominant allele will mask the presence of a recessive allele unless both of the alleles are both recessive (both ww).

So for the WW genotype, we are going to see the dominant phenotype: Widow's peak.

For the Ww genotype, we are also going to see the dominant phenotype since the dominant allele is going to mask the presence of the recessive allele, so we are going to see: Widow's peak.

Lastly, for the ww genotype, we are going to now see the recessive phenotype, since both alleles are recessive: straight hairline. Note that their are two of these type of offspring as stated in the question.

Bt corn is a genetically modified crop that contains a gene from another species. Which characteristic does this gene give the p
Angelina_Jolie [31]

The right answer is D.

The effectiveness of BT-Corn compared to conventional insecticide treatment  is very much higher:

* The plant itself produces the toxin that blocks the digestion of or target insects: the entire plant is protected where a treatment (out of neonicotinoids, very expensive and reserved to the seed treatment) allows only a protection of surface and must be renewed several times.

* The selectivity of the treatment is very superior: each variant of the BT molecule targets only a family of insects but we do not know the impact of their cumulative effects in the environment.
