An amoeba is a single-celled organism that can usually only be seen with a microscope. A scientist measures an amoeba to be 0.10 mm long, and then a group of students measures the organism as well. Which student’s measurement is the most accurate? 0.01 mm 0.05 mm 0.20 mm 0.11 mm

Probably the student measuring 0.20mm.

Explanation:

Under a microscope it is gathered that the size of an amoeba cell could be 0.20mm when its reading is been converted in milli metres(mm).

This volume of the amoeba is so small that useful substances can be distributed and waste materials always removed by a process called diffusion. Oxygen, for example, enters an amoeba and spreads out, i.e. diffuses in all directions at a rate at which oxygen is consumed in respiration. Similarly, carbon dioxide diffuses out of an amoeba with sufficient speed to prevent it accumulating to harmful levels within the cell.

1. loamy sand is about 80% sand with 10% clay and defined mostly by sand particles with some clay to provide structure and fertility. the sand particles are easily visible and the soil holds structure but breaks apart easily.

2. scott sand can improve his soil quality by incorporating more silt and organic matter into the soil. peat moss and organic matter can also be incorporated.

the correct answer is b
