Explanation:
Protozoa and Bacteria: Protozoa are very small one-celled creatures. They play an important role in helping to make the soil better by feeding on bacteria and releasing excess nitrogen, which is really good for plants. Bacteria are among the tiniest and most numerous organisms in the soil.
Answer:
2.58g
Explanation:
First calculate the moles of butane used in the reaction
moles = mass÷molar mass
= 0.85÷58
= 0.0147
According to the stoichiometric ratio:
C4H10 : CO2 = 2:8
moles of CO2 =(8÷2)×0.0147
=0.0586 moles
mass of CO2 = 0.0586×44
= 2.58g
Answer:
B
Explanation:
When a phospholipid is found in a sphere of water, the hydrophilic head is expected to point towards the water while the hydrophobic tail will point away from the water.
The term hydrophilic means water loving, So it is expected that the hydrophilic head will move towards water molecules at it has affinity for water molecules.
The opposite is the case for the hydrophobic tail. The hydrophobic tail moves away from water molecules
What these cases suggest is that both regions are acting base on their chemical make up. While the hydrophilic head contains molecules which are capable of interacting and bonding with water molecules, the hydrophobic tail contains strictly non polar molecules which are not capable of water interaction. Hence the interactions a phospholipid has with water is through its head region
