The reason due to which evolution of multicellular organisms led to the development of the circulatory system. Introduction: Because they consist of several cells, multicellular organisms are structurally complex beings. They can be seen with the unaided eye. They have unique organ systems and organs. Since they are eukaryotes, they have structures that are bound to membranes. The division of work is visible in their cells.

Expert Solution & Answer

Explanation of Solution

Blood arteries that transport blood away from and toward the heart make up the circulatory system. Blood is transported from the heart by arteries and returned through veins. Oxygen, nutrients, and hormones are delivered to cells by the circulatory system, which also eliminates wastes like carbon dioxide.

In multicellular organisms, the nutrients, oxygen, and minerals should be transported to each cell and the metabolic wastes and toxins should be removed from each cell. To enable these transports, the circulatory system evolved in multicellular organisms. For instance, the blood carries oxygen and nutrients that are taken up by the cells, and the wastes like carbon dioxide are released in the blood. This blood is filtered into the kidneys and the wastes are removed from the body.

Conclusion

The circulatory system evolved in eukaryotes to transport oxygen and nutrients to the cells and remove metabolic wastes from the cells.

In order to establish the expiration date of perishable food, growth curve data must be collected. 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 16
