The answer is either b or c because bio means life and diversity means different and the ants stinging other insects get  rid of a population and maybe another species lives off of the species that ant killed.                                                                                                     
When the grasslands are converted into housing projects it gets rid of everything so no trees no animals and no diversity of living organisms other than humans
        
                    
             
        
        
        
The avian
kidneys are divided into units called lobules and as the two avian kidneys of
birds do their work or function, most of these birds excrete nitrogenous waste
known as uric acid from the blood, which reduces water loss but requires more
metabolic energy to produce nitrogenous waste.

Answer:
Option 1, a charged end and a noncharged end
Explanation:
Complete question 
If a small droplet of ordinary fat is suspended in water, the fat molecules form a "ball of spaghetti" with no particular orientation. But if a droplet of phospholipid molecules is put in water, all the molecules point outward, toward the water. Phospholipids are forced into this orientation because phospholipids have _____
-   a charged end and a noncharged end
-   three fatty acid molecules, all pointing in different directions
-   two fatty acid molecules pointing in different directions
-   both a saturated fatty acid and an unsaturated fatty acid
-   two charged ends
Solution 
The structure of phospholipids consists of the following groups and molecules –  
a)	A glycerol molecule  
b)	Fatty acids (2 in numbers) – It is hydrophobic as it is uncharged and non polar in nature
c)	Phosphate group (with alcohol) – It is hydrophilic as it is negatively charged and polar in nature.  
When the phospholipids are placed in  water, the molecule rearranges itself in a way that the hydrophobic head face inside and the hydrophilic head face outside thereby forming micelles.
Hence, option 1 is correct
