Only one species of moth, Xanthopan morgani, is known to have a tongue long enough to reach the nectar in the Madagascar orchid

Angraecum sesquipedale.
Would the orchid be more likely to reproduce if, through many generations, its nectaries became shorter so that other insect species were able to serve as pollinators? (Select all that apply.)a.Yes. If more insect species are able to use the orchid for food, then the orchid is more likely to reproduce.b.Yes. We can predict that the nectaries of these orchids will tend to shorten enough that other pollinators can also feed on them.c.No. If the nectaries were shorter, then the moth Xanthopan morgani would be able to feed without rubbing against the pollen.d.No. If the nectaries were shorter, then insect species that use other flowers as food sources would also drink its nectar, and it would be less likely these insects would visit another orchid of the same species while carrying its pollen.e.All of the above are plausible. It is impossible to predict.

Answer: e.All of the above are plausible. It is impossible to predict.

Explanation:

The long tongue of moth Xanthopan morgani is able to derive the nectar from the orchid. If through many generations the nectaries become shorter the moth may not be able to derive the nectar this may facilitate the other insect species to derive the nectar and pollination.

If more insect species will able to use the orchid for nectar then obviously the orchid is more likely to reproduce due to pollination. The nectaries may get even shorter that the nectar will readily available to the other species of insects. This may also interrupt the pollination of other species of orchids as Madagascar orchid is a source of nectar which will attract many pollinators also those were specific to the other orchid species.

All conditions are plausible. But several generations of evolution of the Madagascar orchid is required to be observed to predict the association of insects with the orchid.

)What type of questions cannot be solved by scientific methods?

Hi!

Questions that we cannot answer with science are going to be ones which are subjective, or, opinion related.

For example, could we follow the scientific method in order to successfully see that Mandy's favourite colour is 'blue' and her grandma's favourite food is 'pizza'? 

Well... I... I guess, but... It doesn't make sense! These have nothing to do with science, as they are all just opinionated! 

Hopefully, you get the picture. =)

Hello,

Please find below a short summary on the subject you have been assigned. This will help you in completing your project and also give you an overview on the current research on this subject.

Food additives are chemical substances added to food in order to either maintain or improve its physical characteristics such as taste, texture, appearance and even freshness.

The long term effects that these substances have on the human body are still largely unstudied. According to the hypothesis called "chemical obesogen", these synthetic compounds are contributing factors to the global obesity epidemic.

Although evidence-based scientific research is still lacking, the support for this hypothesis is growing as many of these additives have been found to disturb the body's endocrine functions.

Furthermore, artificial preservatives used today may increase the risk of inflammatory bowel disease. This has been shown by a study on mice in which the food additives known as emulsifiers (carboxymethylcellulose and polysorbate-80) have been shown to affect the animal's health.

Due to these chemicals, the mice not only became obese but also developed metabolic problems such as glucose intolerance.  It seems that these chemicals affect the gut bacteria population in a negative way, as mice lacking gut bacteria did not become ill.

The mice study was followed by another study in which the human simulated through a series of flasks. Under the influence of the emulsifiers arboxymethylcellulose (E566 on EU labels) and polysorbate-80 (E433), the levels of bacterial protein called flagellin increased. This protein is known to cause inflammation at high concentrations. The next step in the study will be the first human trials.

Due to the long road our food takes from the farm to our table more extensive research is required. There are thousands of compounds that change the biochemical properties of the plants and animals that constitute our diet. The effects of the degradation and accumulation of these compounds are still unknown and thus many more studies and approaches are required in order to insure healthy food and stop the current obesity epidemic. Everything that is added to our food should be carefully analyzed.
