They help in reducing many diseases that can spread through dead and decaying matter and also foul smell
Lake is the large body of water found inland and usually feed by a stream.
Explanation:
Lake is a water body that is found inland and usually feed by stream or rivers . Lakes supply drinking water to the cities. Lake plays huge role by providing water to the people which are used for various purpose agriculture, drinking, irrigation. It prevents flood and during dry season it maintains a flow of water. Lakes are also used for hydel power development.
Lake store water and during shortage it provides water . Lakes improves water quality as well as increases the groundwater level and also help in preserving biodiversity.
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.
Answer: Both groups are bilaterally symmetric triploblasts with the protostome pattern of development.
Explanation:
Lophotrochozoa and Ecdysozoa are bilaterally symmetrical clade of aminals. They are triploblastic and they possess protostome pattern of development that is to say in their embryonic development, the mouth develops first before the anus.
