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.

Compare the arrangement of muscles in earthworms to amphioxus
mafiozo [28]

Earthworms have two muscles which is used in locomotion. Both muscles are circular and longitudinal (inner layer of the series of muscles). The diameter of the earthworms body is reduced when the circular muscles are contracted which makes them appear to be thin. The worm appears short when the longitudinal muscles contract thus, its length is reduced.

 

Amphioxus on the other hand,  have two unique muscle fiber types. This includes  deep fibers and smaller but mitochondria-rich superficial fibers. E<span>ach of which has its own innervation.</span>
