Answer:
Explanation:
National Park Service has been keeping the native ponies on Ocracoke Island since the 1960s. It is believed that these ponies arrived and left by the ships. These ships required to lower their load thus they left the ponies on the Island. These ponies are known as Ocracoke ponies and also called as Banker ponies. These ponies share a link to old Spanish horses genetically. The unique characteristics of the ponies include one fewer lumbar vertebrae, greater bone density, short necks, wide foreheads, and one fewer rib.
 
        
             
        
        
        
Answer:
These are the basic steps of urine formation.
Explanation:
The first step comprises creating a filtrate in the glomerulus. 
During the second stage, the filtrate flows through the tubules, and useful substances are reabsorbed. 
Waste products will then be secreted by the tubules. 
Whereas, the final stage is the conservation of water that occurs in the renal tubule.
There are four major stages in the formation of urine.
 
        
             
        
        
        
Answer:
d. less than 100% of the energy captured from sunlight is transformed into potential energy in the form of a hydrogen ion gradient and then into potential energy in the form of covalent bonds
Explanation:
Photosynthesis is process utilized by plants, several bacteria and protists to convert the light energy to chemical energy. So they utilize the photosynthesis as the powerhouse for the energy production. Heterotrophs like human that cannot synthesize their own food, use this converted form of energy by autotrophs.
During the light reaction of photosynthesis the photons from light are absorbed by photosystem I and II. These photons excites the electrons which flow through the electron transport chain from higher potential to lower potential. These electrons release the energy while moving from higher potential to lower potential which is utilized by H+ pump to pump the H+ to lumen of plastids from stroma and of course not the 100% energy is utilized some of the energy dissipates. . So this process causes the accumulation of high potential H+ ions across the membrane. These H+ ions are utilized for the production of ATP by ATP synthase complex when they flow back to lower potential across the membrane through ATP synthase complex.
The ATP and NADPH produced from light reaction are utilized to combine carbon molecules during dark reaction. The covalent bond is used to combine the carbon molecules and we know that combining carbon molecules stores energy in the form of covalent bond.
