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:
B. Food was a limiting factor.
C. As long as Ling keeps adding more food, the guppy population will continue to grow
Explanation:
Limiting factor refers to biotic or abiotic factors that limit or affects the growth of species. In the population of guppies, food was a limiting factor that affects their population growth. Indeed!, it is vivid from the experiment that after Ling increases the amount of food being given to the guppies, there is a significant increase in the population growth.
We can thereby conclude that the following statements that supported these data goes thus;
Food was a limiting factor and as long as Ling keeps adding more food, the guppy population will continue to grow.
Answer:
Construction of Fish Ladders to provide a mechanism for migrating species to move upstream.
Explanation:
So that way, the fish and other creatures can continue living the way they were.
It changes because it goes through phases of growth and changes size and it developed more.
Hope this helps.
