Answer:
Before life began on the planet, Earth's atmosphere was largely made up of nitrogen and carbon dioxide gases. After photosynthesizing organisms multiplied on Earth's surface and in the oceans, much of the carbon dioxide was replaced with oxygen.

Refined carbohydrates are digested faster, leading to a fast rise in blood glucose levels.
Refined carbohydrates have a higher glycemic index than processed whole grains. That's because of their simple chemical structure, leading to powerful spikes in blood
sugar and insulin secretion. This immediate impact can lead to an increased risk for type 2 diabetes, overweight and heart disease. 
        
             
        
        
        
Answer: 
Deoxyribonucleic acid (DNA) hold the hereditary material that acts as a blueprint for the development and functioning of life process on the earth. It is a blueprint for every cell in every organism.
Its major function is to encode the DNA sequence of amino acid by using the triplet genetic code that code for a specific protein that perform a specific function in the body that are necessary for the normal function of the life processes.
 
        
                    
             
        
        
        
La biogénesis es el proceso fundamental de los seres vivos que producen otros seres vivos. Ejemplo: una araña pone huevos de los que saldrán más arañas. La biogénesis es aquel principio según el cual la vida solamente se origina de una vida preexistente (que ha existido antes).
 
        
             
        
        
        
The question is incomplete as it does not have the options which are:
- Simple squamous
- Simple columnar
- Pseudostratified squamous
- Stratified squamous
- Stratified columnar
Answer:
Stratified columnar
Explanation:
Epithelial tissue is the tissue formed by the cells which form a layer of cell and lines the lumen of the organ and also covers the organs. The epithelial tissue can be classified based on the number of layer and shape of the cell.
In the given question, the shape of the cell is slender and are tall therefore are called columnar. The cells form more than one layer or multiple layers therefore form stratified layers.
Therefore,  the epithelial tissue formed by these slender shaped multiple layers is known as the stratified columnar layer. The stratified columnar is present in the respiratory tract and the digestive tract.
Thus,  Stratified columnar is the correct answer.
