It would lower the pH, raise the acidity of the water, and it would kill off a lot of marine life if it got too high. As species begin to die their predators follow, and this could cause mass extinction.
        
                    
             
        
        
        
Answer:
Topographically SN is classified into:
1. Central SN- made up of the brain and spinal cord
2. Peripheral SN- made up of nerves (31 pairs of spinal nerves, 12 pairs of cranial nerves), nerve plexuses and nerve ganglia
Structural Dpdv
1. Somatic SN \ of relationship life
2. Vegetative SN a) sympathetic- acts in unusual conditions (eg stress, fear)
b) parasympathetic- acts in normal life conditions

Answer:
The cell membrane of the living organism is made of the lipid bilayer and proteins. The most common lipid present in the plasma membrane is the phospholipids.
Phospholipids has both the hydrophobic tail and hydrophilic head. The hydrophobic region interacts with each other. The lipid layer of phopholipids gets in association with the hydrocarbon chain of triglycerides. Their hydrophilic part dissolve in each other.

Answer:
The chlorophyll pigment have photosystem 680/ PS I which captures the sunlight. Then the pigments gets excited and photosynthesis starts. Without chlorophyll photosynthesis can't happen.
Explanation:
Photosynthesis occurs in the chlorophyll pigment of the plant. They have the capacity to trap light energy and convert its energy to form glucose and oxygen.  
The chlorophyll is a double layer membrane structure. In it two photosystems works i.e. photosystem I and photosystem II. In the photosystem I light is trapped.  
In the chlorophyll thylakoids are present which have photosystem 680. It captures the photons coming from the sun. The photons are the light of different wavelengths which are absorbed by plants.  
The photon have more energy, and when it comes in contact with PS 680, the pigments get excited. Then they release high energy electrons which helps to form ATP, NADPH. Because it is a light dependent reaction.
Glucose and oxygen are formed in the stroma as it does not require light. It is a light independent reaction.
Therefore, chlorophyll is first require to capture photons coming from sun.
