Answer:
In order for a polar compound to enter into the hydrophobic space of the phospholipid tails, it would need to break the many <u>polar covalent bonds</u> bonds it has formed with the water and enter into a space where these bonds cannot form. Therefore, it is not a repelling action but a "lack of attraction".
Explanation:
<u>Water as polar solvent and the phospholipids:</u>
Water is very different on the molecular and that is due to the more polar nature, which is caused by the hydrogen bonding with in a H₂0 molecule. As the water molecules forms bonds with the other molecules in a specific formation of unequal polarities on its molecules. As the molecules have an unequal amount of charges present on it. For, the phospholipids they have two hydrophobic tails and the hydrophilic head. Through which they form most of the cell membrane structures.
In order to add any polar molecule to the hydrophilic head of the phospholipid there are many covalent bonds which are required to be broken, as these bonds include the covalent bonds found inside the molecular level. While, the hydrophobic tails of the molecules can't arrange themselves to form the bonds with the polar molecules more frequently.
Answer:
A) The role of bacteria fixing nitrogen is very important because it fixes atmospheric nitrogen in the roots of plants. For example, Azotobacter is a bacteria which lives in the root of the higher plants. The bacteria fixes nitrogen for the plant and the plant gives habitat and food to the bacteria and hence, both get benefit.
B) Nitrifying bacteria are the bacteria which converts ammonia into nitrates. Examples are Nitrosomonas and Nitrobacter.
C) Denitrifying bacteria is a type of bacteria which converts nitrates into atmospheric nitrogen. Examples are Serratia and Pseudomonas.
Option A would be the appropriate one as we know the common formula of carbs is CH2O we can get C10H20O10 by that formule! :)

Answer:
Seven days after a spring tide, the sun and moon are at right angles to each other. This produces moderate tides known as neap tides, meaning that high tides are a little lower and low tides are a little higher than average. Neap tides occur during the first and third quarter moon, when the moon appears "half full.
