Answer is C. The man is twenty thousand (2 x 10⁴) times larger than the paramecium.
1 meter (m) = 10⁶ micrometers (µm)
Therefore, 1.7 m = 1.7 × 10⁶ µm
Thus, the length of the man compared to the length of the paramecium will be
1.7 × 10⁶ / 85 = 2× 10⁴ .
Therefore, length of the man is 2× 10⁴ times larger than the length of the paramecium.
A microscope is an instrument which makes an object appear bigger than it is. It took the invention of this relatively simple tool to lead to the discovery of cells<span>. In the 1660s, Robert Hooke began using microscopes to look at all sorts of materials. Anton van Leeuwenhoek took up similar work in the 1670s.</span>
Answer:
Whether a cell uses facilitated diffusion or active transport depends on the specific needs of the cell. For example, the sugar glucose is transported by active transport from the gut into intestinal epithelial cells, but by facilitated diffusion across the membrane of red blood cells.
Explanation:
In coniferous forests, the terrestrial biome receives precipitation of up to 300 to 900 millimeters (mm) each year.
Coniferous forests mainly consist of conifers and grow trees that produce thick needles and cones instead of growing flowers and leaves.
These are evergreen plants and stay green, healthy, and sustainable all year long.
In spite of flowers, these trees bear needles annually.
Moreover, conifers are very adaptive trees that can grow in very cold and dry climate zones.
It is due to their adaptability that they can survive all year long without losing a life.
Siberian fir, Dahurian, and Siberian larches are examples of confer forests.
