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.

Once the microbial load is so high that it poses a hazard to human health, the food item is no longer considered safe (expired). Generally a load of x50,000 bacteria/gram is considered unsafe. Your task is to determine the microbial growth curves for MicroYo, a new brand of yogurt. The growth is determined by sampling the yogurt and growing the bacterial isolates in broth culture which is then serially diluted by a total of x10,000 and inoculated onto standard petri plates of nutrient agar. The following colony counts are measured: Time (days) MicroYo colony count# 1 1 4 1 12 2 16 20 4 7 What day should you recommend expiring the yogurt (the last possible date before the microbial load is unsafe). 12 4 20 16arrow_forward
