<span>Under normal conditions, the forced expiratory volume is normally 75-85 % of the vital capacity.
According to its definition, forced expiratory volume (FEV) refers to "how much a person can exhale during a forced breath." And a person can exhale from 75 to 85 percent of their entire breathing capacity. This is one of the tests to check the function of the lungs. </span>
The greatest percent of mass of the universe is dark matter
Answer:
2.6 kilo Ohm
Explanation:
Capacitance, C = 591 μF = 591 x 10^-6 F
Vo = 88.5 V
V = 11.9 V
t = 3.09 s
Let the resistance is R.
Take natural log on oth the sides
ln 0.135 = - 3.09 / RC
RC = 1.545
R = 1.545 / ( 591 x 10^-6)
R = 2614.2 ohm
R = 2.6 kilo Ohm
Thus the resistance is 2.6 kilo Ohm.
C. Establishing a seed bank with a variety of seeds of
different crop species
Explanation:
Establishing a seed bank with a variety of seeds of different crop species is a cooperative behavior that would best enable humans to prevent the problem of loss of biodiversity of cultivated crops.
- Modern agricultural practices is profit driven and centered on mono-cropping.
- Mono-cropping is an agricultural practice in which only one crop type is cultivated on a mechanized scale.
- Mono-cropping leads to less diversity of crop species as just only the cultivation of economically important crops are encouraged.
- In order to avert the menace that comes along with mono-cropping, seed banks are viable place to keep and protect other plant species from going into extinction.
- Seed banks provides a preservation of different plant species by focusing on storing their viable seeds.
