Bio homework help :)?Two populations of birds with somewhat different coloration live on opposite sides of a peninsula. The habitat between the populations is not suitable for these birds. When birds from the two populations are brought together, they produce young whose appearance is intermediate between the two parents. These offspring will breed with each other or with birds from either parent population, and all offspring of these pairings appear intermediate to various degrees. (use to answer Q 1.) 1.What keeps the two populations separate? behavioral reproductive isolation temporal reproductive isolation lack of hybrid viability spatial reproductive isolation They are already separate species. 2. Three populations of crickets look very similar, but the males have courtship songs that sound different. What function would this difference in song likely serve if the populations came in contact? a postzygotic isolating mechanism b prezygotic isolating mechanism c gametic reproductive isolating mechanism d behavioral reproductive isolating mechanism e two of the above 3. The peppered moth provides a well-known example of natural selection. The light-colored form of the moth was predominant in England before the industrial revolution. In the mid-nineteenth century, a dark-colored form appeared. The difference is produced by a dominant allele of one gene. By about 1900, approximately 90% of the moths around industrial areas were dark colored, whereas light-colored moths were still abundant elsewhere. Apparently, birds could readily find the light moths against the soot-darkened background in industrial areas and therefore were eating more light moths. Recently, use of cleaner fuels has greatly reduced soot in the landscape, and the dark-colored moths have been disappearing. Should the two forms of moths be considered separate species?a. Yes, because natural selection has affected the frequency of the two different forms.b. Yes, because they have completely different coloration.c. Yes, because they are reproductively isolated based on habitat.d. Yes, because they have completely different coloration and natural selection has affected the frequency of the two different forms. e. No.

Suppose that there is a town called Cellville. What cell organelle would have a similar purpose to the roads throughout the town?

Answers

The answer is endoplasmatic reticulum.

Endoplasmatic reticulum forms a network of flatten tubules in the eukaryotic cells. It is involved in a synthesis of proteins and lipids. It enables transportation of proteins to the Golgi apparatus. Since enables transportation, a purpose of the endoplasmatic reticulum in the cell can be compared to a purpose of the roads in the town.

Enzyme function is critically important for the proper replication of DNA. Predict the consequence of a loss of function for:

Answers

The consequence of a loss of enzyme function for the proper replication of DNA is that the replication process may be disrupted or halted altogether. This can lead to errors in the DNA sequence, which can result in genetic mutations or abnormalities.
