I'm not 100% sure which biology class you are in are you doing the moth activity? If so then I would believe that the light moth would be easier to see on a dark tree trunk
The two sources of information used to direct the expression of genes during various stages of development are Transcription and Translation.
<h3><u>Explanation:</u></h3>
Both of them combined is called gene expression.Transcription is the process of sharing information stored in a DNA to RNA.
The process of translation is carried out in cytoplasm. Here, the mRNA, in which stands for messenger, send messages to a more complex and specialized molecule called the ribosome. The sequence present on the mRNA base is read by the ribosome.
Transcription takes place in nucleus and translation takes place in Cytoplasam. The products of transcription are mRNA, tRNA, rRNA. The products of translation are Proteins.
Answer: d
Explanation: an ecosystem is a habitat that benefits the inhabitants
Answer:
1. fossil record:
Fossils are organisms that get buried in sedimentary rocks. These are formed at different times. The study of fossils existing in the different rock layers indicates the time period when they existed. Thus different life forms have been formed at different times in the history of the earth.
fossil bird Archaeopteryx is considered as a connecting link between reptiles and birds indicating that birds evolved from reptiles.
2 comparative anatomy:
Homologous organs - such organs that have different embryonic origins but play different roles.
The forelimbs of whale, bat, deer, rabbit
Homologous organs - such organs that are the same in structure and embryonic origin but play similar roles.
wings of a bird and wings of the insect. The wings of the birds are modified
3. DNA sequence can be helpful in finding relations among organisms. Biogeography also helps in identifying the geographical distribution of organisms, to know how and when species may have evolved.
Answer:
The evidence from the Hershey-Chase experiment demonstrated that DNA, not protein, is the genetic material DNA contains phosphorus, but protein does not was as result of some analysis in which it was discovered that Protein contains sulfur and DNA does not.
This was what led to the use of radioactive phosphorus and radioactive sulfur in self-identification.
