Parasitic plants have lost many of the morphological and genetic traits necessary for an autotrophic lifestyle. From an evolutionary point of view, how do you think this happened?

This has been observed in the holoparasitic plants. The carbon source used by the holoparasitic plants was from the host plant cells. These plants generally do not have chlorophyll. Parasitism is referred to as the interaction in which there would be consumer resource. As a consequence of evolution, there occurs negative selection of some of the traits which would be neutral, since the phenotypes that are associated with those traits are becoming redundant. This process is referred to as the process of evolutionary compensation. An example is the lack of synthesis of lipids, within some of the parasites. By manipulation of the host in an exploitive manner, the parasites obtain lipids. Most traits are lost as s result of negative selection

Many chronic diseases are linked to diet and lifestyle behaviors. There have been many proposed solutions to dealing with this problem. Please state your opinion on these 3 proposals; don’t just answer “yes” or “no,” provide some background and reasons for supporting your opinion. Use facts to back up your position. 1) Diabetes and heart disease combined kill more Americans than any other disease. Both of these diseases are strongly linked to obesity. Based on these facts, would you support...

1. What foot traits and corresponding functions seen in other primates have we lost in our feet? Why would we have lost helpful features such as this? 2. Based on what we know of their physical and cultural traits, how were Neandertals adapted for their life in Ice Age Europe? Did early humans in Europe have these same adaptations? How might these adaptations relate to the extinction of the Neandertals and the continuation of humans? (Hint: Is is possible to...

1.Many of the traits we learned about in this lab have had a lasting effect on our lineage, and as a human, you still bear their consequences today. For example, humans are at high risk of knee injuries, such as tears in the ligaments that support the knee joint between the femur and tibia. What adaptation that traces back to australopiths, like Lucy, might put additional strain on your knee? Why would a trait with such negative consequences have evolved?...

Because of the coronavirus crisis, many people have lost jobs and young students are not able to find jobs. The government of Canada has stepped in to help people in this kind of situation with regular payments called emergency benefits. Are these payments also acting as incentives for people make decisions to help reduce the spread of coronavirus? Explain.

Populations evolve for many reasons. Suppose there is a population of plants that have either purple flowers or white flowers

Populations evolve for many reasons. Suppose there is a population of plants that have either purple flowers or white flowers, and the allele for purple flowers is dominant. This means that plants with two purple alleles have purple flowers. Plants with one purple allele and one white allele also have purple flowers. Only plants with two white alleles have white flowers. For each event or condition described below, answer the following questions. Which mechanism of evolution is at work? How...
