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.

What is the function of a circulatory system? a) It brings a transport liquid into close contact with all cells in the body. b)
Tomtit [17]

Answer:

The correct answer is a) It brings a transport liquid into close contact with all cells in the body.

Explanation:

The circulatory system helps in bringing the blood which is a transport liquid in close contact with the cells present in our body. This helps in gas exchange between cells and blood. The circulation of blood in the body occurs by the pumping of blood by the heart into arteries, veins, and capillaries.

This circulation of blood plays many other vital functions like transport of nutrients to the cells, transport of waste products from the cell to outside the body, transport of hormones, maintenance of body temperature, etc.  

So all these processes become possible when transport liquid comes in contact with the cells. Therefore the right answer is a.
