Answer:
Plain Tap Water
Explanation:
You should find that plain tap water produces a much larger, stable drop of water on top of the penny than the soapy water does. This is because plain tap water has higher surface tension, so the surface is "stronger" and can hold together a larger drop.
<span>Bacteria are necessary because they are doing the very important processes for the nitrogen cycle like as ammonification, nitrogen fixation, and nitrification.
As Nitrogen cannot be used in its form because of its chemical form so it is changed to various forms in the nitrogen cycle, bacteria has a big help in the process.</span>
Answer:
c. Fungi
d. Yeast
Explanation:
Both fungi and yeast will be effectively removed by a 0.22 micron pore size filter.
<em>The size of microscopic fungi ranges from 2 to 10 microns while the size of yeast ranges from 3 to 4 microns in diameter. Hence, both organisms will be effectively filtered off by a 0.22 micron filter paper.</em>
The size of bacteria ranges from 0.2 to 2 microns while that of virus is in nanometer. Hence both cannot be effectively removed by a 0.22 micron pore size filter paper.
The correct options are c and d.
1. With there sent- either a nice smelling fragrance or a horrid stench.
2. The bright colors of its petals or leaves Hope this helps
Answer:
The correct answer is : 144.
Explanation:
Given:
K or carrying capacity = 2000
N or population size = 1200
rmax or maximum per capita growth rate = 0.3
formula:
growth rate = 
Solution:
by the formula ,
growth rate =
= ![360 [\frac{800}{2000}]](https://tex.z-dn.net/?f=360%20%5B%5Cfrac%7B800%7D%7B2000%7D%5D)
= 360 × 0.4
= 144
Thus, the correct answer is : 144.
