Explanation:
La siguiente entrada tiene como objetivo realizar una breve explicación sobre las moléculas biológicas  lipídos y carbohidratos, las cuales son muy diversas ya que están formadas por carbono, lo cual hace que puedan formar muchos tipos de enlaces. Esta capacidad permite que las moléculas orgánicas  adopten muchas formas complejas, como son las cadenas, las ramificaciones y los anillos.
Las moléculas biológicas son grandes polímeros que sintetizas para poder enlazarse con otras subunidades mucho mas pequeñas conocidos como monómeros. Las cadenas de subunidades estan unidas por enlaces covalentes los cuales se forman por deshidratación, estas cadenas pueden romperse por hidrólisis. La moléculas biologicas más importantes son los carbohidratos, lípidos, proteínas y ácidos nucleicos.
 
        
             
        
        
        
The concept of the struggle for existence<span> concerns the competition or battle for resources needed to live. It can refer to human society, or to organisms in nature. The concept is ancient, and the term </span>struggle for existence<span> was in use by the end of the 18th century. From the 17th century onwards the concept was associated with a population exceeding resources.

Rain occurs because of moisture gathering higher in the atmosphere. The process that creates rain in the atmosphere has a variety of steps we don't see. This process is called the water cycle. This cycle is never ending, meaning that rain is a constant on the earth as long as there's an ocean or water on the earth. 
Water vapor is an atmospheric moisture that is sometimes visible to the naked eye. Water vapor comes in the form of clouds, fog, mist, and dew. The process that creates water vapor is called evaporation, which is where water on the earth is heated to a temperature that makes water molecules spread out and begin to vibrate quicker. This creates water vapor. 
The water vapor is commonly carried high into the atmosphere to create clouds. Once the vapor is in the atmosphere, it begins to lower in temperature. This causes condensation, which means the water vapor is reforming into water droplets. 
Precipitation Takes place after this. Precipitation occurs when the water droplets are too heavy to carry in the atmosphere, so they drop back down to the earth. After this takes place, the entire process resets, and happens again.
Hope this helps!  
 
        
             
        
        
        
The correct option is ALDOSTERONE.
Angiotensin ll is one of the most potent sodium retaining hormones. It regulates aldosterone release from the adrenal cortex. The aldosterone hormone stimulates sodium re-absorption through mineralocorticoid receptors in the connecting and cortical segments of the collecting tubules.
