C) esophagus - moves air from the nose into the lungs
Explanation:
The oesophagus is a muscular tube with a sphincter valve at each end. Its main function is to transport food and fluid, after being swallowed, from the mouth to the stomach.This is propelled from the pharynx into the oesophagus, and towards the stomach in a peristaltic waves. The peristalsis also pushes food along the alimentary canal
The correct answer is D) The fossil record reveals intermediates that link different species. Hope this helps.
According to the law of conservation of energy, energy is not lost, although kinetic energy can be converted into thermal energy by friction. hope i helped <3
Answer:
1. Photosynthesis
2.carbon dioxide
3. fossil fuel
4.cellular respiration
Explanation:
Photosynthesis is the important function takes place mostly in green plants which converts inorganic compounds, water, carbon dioxide to the glucose or organic compound in presence of light energy. It is an important reaction that is required for energy and for food for almost every organism.
Carbon dioxide is the carbon source for the plants to produce glucose or simple sugars with help of water and light energy.
Fossil fuels are formed by the process of decomposition of organic compound and organism of the prehistoric organism which is a carbon containing energy source.
Breaking down or catabolism of glucose in order to produce energy in the form of the ATP is called cellular respiration which is essential for cell to perform cellular functions.
Amino acids are acids on one hand, and a base on the other hand.
<h3>What is an acid?</h3>
An acid is a substance that produces hydrogen or hydroxonium ions as the only positively charged ion when it ionizes.
All amino acids have an amine group -
and a carboxylic group -
.
The carboxylic group ionizes such that:

The presence of the amine group enables amino acids to also act as a base.
