To determine:
The potential consequences if honeybees were to go extinct.
Introduction:
Coevolution is a process in which one species undergoes modifications in its structure in response to the other species that have adapted itself; thus, both species are finally fit for each other. The best example of coevolution is bees and flowering plant that must contain colorful flowers that causes accommodation of bees.
Explanation of Solution
About 20,000 species of bees work as a pollinator for plants. Honeybees are the best-known pollinator onto the Earth. There are many plants and flowers that are mostly dependent on bees for pollination. Honeybee’s eyes are capable to see ultraviolet wavelengths; hence bees-pollinated flowers are bright in color. These flowers contain nectar guides that have ultraviolet shedding where a reproductive portion is present.
Humans are unable to detect ultraviolet rays; but bees can easily detect these rays, and are sensitive to these rays. Bees have proboscis that help them to feed nectar from several flowers and pollen tubes by their hinge legs. There are many plants and flowers that are mostly dependent on bees for pollination. Thus, this is a major concern that the number of honeybees were go to extinct. Human activities such as the use of herbicides and pesticides cause death of honeybees; some diseases are also responsible for their extinction.
Therefore, extinction of honeybees leads to the decline of various plants and flowering species that are dependent on honeybees for pollination. Due to the extinction of bees, pollination will get disrupt that will cause disruption in the propagation of many species of plants.
Coevolution gives opportunities to flowering plants to attract pollinators to produce many seeds. Plants and their pollinators undergo adaptations and modification to one another.

- You will use the following scenario to answer a group of 5 questions. You have isolated a microbe from an environmental sample. The microbe has the ability to perform a new metabolic reaction at a very low temperature, so you are excited that it could be a new species. You have shipped your samples off for sequencing and are now waiting for the results. Out of curiosity (and maybe boredom...) you decide to test your culture for the Catalase and Oxidase enzymes. Upon testing your sample for catalase, you don't see any bubbles; however, you do see a color change to purple during the Oxidase test. What results can you conclude from this? O Catalase-/ Oxidase + O Catalase +/ Oxidase + Catalase + / Oxidase- O Catalase / Oxidase - O None of the abovearrow_forwardWhich of the following is not a strength of using 16S rRNA for phylogenetic analyses? OA. It's cheap OB. It's easy to do C. It can be used to identify all the way down to the strain level OD. Both A & B OE. None of the abovearrow_forwardWhy are molecular approaches important to the field of microbial taxonomy and phylogeny? Phylogenetic inferences based on molecular approaches provide the most robust analysis of microbial evolution currently available. It allows for the collection of a large and accurate dataset from many organisms Almost no fossil record was left by microbes when compared to plants and animals All of the above None of the abovearrow_forward
- You will use the following scenario to answer a group of 5 questions. You have isolated a microbe from an environmental sample. The microbe has the ability to perform a new metabolic reaction at a very low temperature, so you are excited that it could be a new species. You have already cultured it and gone through the plate isolation procedure. Before you ship your samples off for sequencing, you want to do one final check of the A260 ratios. You get back the following ratios: A260/280 ratio is 1.89; A260/230 is 2.01. These ratios are close enough to the accepted "pure" values so they could be considered "pure" and mostly (if not completely) free of contaminants from the PCR process. True Falsearrow_forwardYou will use the following scenario to answer a group of 5 questions. You have isolated a microbe from an environmental sample. The microbe has the ability to perform a new metabolic reaction at a very low temperature, so you are excited that it could be a new species. After receiving your sequence back from the sequencing lab, you feel that you have, in fact, discovered and isolated a new species. You ask a fellow labmate about how you should proceed, and he tells you the following is the proper way to introduce a new species for recognition: Cultures have to be sent to international culture collections. Then a paper must be published describing the new organism and providing a genus and species name. You recall learning about this in your Microbiology course in college. Is this information from your colleague true or false? True Falsearrow_forwardis often a good indication of phylogenetic relatedness in phenotypes.

You have isolated a microbe from an environmental sample. The microbe has the ability to perform a new metabolic reaction at a very low temperature, so you are excited that it could be a new species. You have decided to send your sample off for sequencing. You need to determine which type of sequencing to use for the preliminary identification of your species. You decide that, for now, you only need to be able to identify the family and genus levels. Which type of sequencing do you think is the most appropriate?
