Oksanka [162]
<h2>False  </h2>

Explanation:

Alimentary canal components include mouth, pharynx, esophagus, stomach, small intestine and large intestine whereas liver is a component of the accessory digestive system

  • The liver and these organs work together to digest, absorb, and process food
  • The liver's main role is to filter the blood coming from the digestive tract, before passing it to the rest of the body
  • The liver also detoxifies chemicals and metabolizes drugs
  • The liver secretes bile that ends up back in the intestines and also makes proteins important for blood clotting and other functions

What connects the nitrogenous based to each other?
Keith_Richards [23]

Hello!

There are two possible answers to this. The one I'm assuming you're looking for is hydrogen bonds.

Hydrogen bonds are the bonds which hold together the double helix shape of DNA. These bonds result from a positive and negative charge drawing two molecules closer to each other. These bonds are generally seen as weak, however, since there are so many of these bonds (as there are so many nitrogenous bases in one strand of DNA), the double helix strand is fairly strong.

Hope this helps!
