The inside of a stomach is coated with a lining that protects it. 
This lining is made up of cells called epithelial cells. They coat the stomach with a mucus that neutralizes the acid.
The mucus contains bi-carbonate (a base), similar to baking soda. 
Acid + Base = water and salt 
So, that’s why taking tums or swallowing baking soda water helps an upset stomach. 
When your stomach is upset, it means there’s too much acid. Taking a tums neutralizes that overproduction eating also helps to absorb the excess acid.
        
             
        
        
        
Answer:
The correct answer is c. are as genetically similar as other siblings.
Explanation:
Dizygotic twin are the twins which developes from two different fertilized egg. So a dizygotic twins can be both male, both female or one male and one female. As dizygotic twins are produced by fertilization of two different gametes, therefore, they share just half of their gene like other siblings share.
Therefore dizygotic twins are as genetically similar as other siblings. Monozygotic twins are the twins that are produced from a single fertilized egg which splits into two eggs. So monozygotic twins share 100% gene, therefore, they are called identical twins. So the correct answer is c.
 
        
             
        
        
        
Answer:
Rods are responsible for vision at low light levels (scotopic vision). They do not mediate color vision, and have a low spatial acuity. Cones are active at higher light levels (photopic vision), are capable of color vision and are responsible for high spatial acuity. The central fovea is populated exclusively by cones.
 
        
                    
             
        
        
        
The Cretaceous–Paleogene (K–Pg) extinction event (also known as the Cretaceous–Tertiary (K–T) extinction) was a sudden mass extinction of three-quarters of the plant and animal species on Earth, approximately 66 million years ago.
