If a student made a model of an onion skin cell using a microscopic magnification scale of 500:1 and the length of the modeled cell is 15 cm, the real cell's length would be 0.03 cm.
The scale is 500:1. This means that the dimension of the real cell without being magnified under the microscope would be 1/500.
Thus, if the length of the cell under the microscope is 15 cm. This length has been multiplied by 500. In order to get the real length, it must be divided by 500.
15 x 1/500
= 0.03 cm

Answer:
True.
Explanation:
Prokaryotes and eukaryotes shows various similarities as well as differences among themselves. The eukaryotes have well defined nucleus whereas such nucleus is absent in prokaryotes.
Prokaryotes are much smaller in size than eukaryotic cells. The small area has large surface area to volume ratio. This ration helps in the process of diffusion and metabolism in prokaryotes. Due to their small size, prokaryotes have large surface area to volume ratio than eukaryotic cells.
Thus, the correct answer is option (a).
Answer:
Atoms
Cells
Tissues
Organs
Organ Systems
Organism
Explanation:
In order of size smallest to largest.
Answer:
El statement that say Direct observation is the simplest and most effective method to determine population size is false.
Explanation:
Simple observation results in an inadequate method for estimating the size of a population, especially if it is very large and mobile. A simple and adequate method consists of counting individuals within a population, with some limitations.
Currently, in large populations, it is common to divide an area occupied by a population into quadrants, count individuals, and then extrapolate the data to the actual dimensions of the space occupied by that population.
