Two different organisms were studied in a carrying capacity study. One was a paramecium population that grew in a flask in a lab

Gre4nikov [31]

Answer:

Paramecium- 0 days/ 50 paramecium

5 days/400 paramecium

10 days/ 900 paramecium

15 days/ 860 paramecium

Bear- 0 days/ 2 bears

20 years/ 26 bears

40 years/ 230 bears

60 years/ 250 bears

80 years/ 248 bears

100 years/ 252 bears

Explanation:

The population of the paramecium will keep on increasing until an equilibrium is reached. The resources will become limited and hence, the paramecium will start competition for the limited resources. As a result, the population of the paramecium will decline rapidly after equilibrium.

The growth rate of bear is very less as compared to that of paramecium growth rate. Along with the growth rate, there are other factors which will be responsible for its numbers such as resources, hunters etc. Also, it uses sexual method of reproduction hence the growth rate will not be like the paramecium growth rate.

Someone new is preparing media for lab and adds buffers to the EMB agar that raise the pH to 7.8. The starting pH of EMB plates

mestny [16]

Answer and Explanation:

Eosin Methylene blue agar or EMB agar consists of sucrose, lactose, methylene blue and Eosin Y. These segments make it a differential medium which permits development of gram-negative microorganisms. Gram positive microscopic organisms develop inadequately on this medium.

It is particular for development of gram-negative microscopic organisms. It likewise separates between non-fermenting gram negative enteric microscopic organisms and lactose fermenting.

Lactose fermenting gram negative microscopic organisms use lactose to deliver corrosive which changes the shading to dull purple. Some of the lactose fermenter will exhibit dim provinces with green metallic sheen while different settlements with purple focus. Green metallic sheen is because of creation of solid acids.

In the event that the beginning pH is 7.8 rather than 6.9-7.3, the color won't change shading regardless of creation of acids. Consequently, it won't be conceivable to separate between lactose fermenter and non-fermenters.
