There are 3 controlled variable
The atria are the heart chambers which receive blood from other organs into the heart. The structure of the atria is determined by the type of function which they performed. Atria are thin walled with no inlet valve and their contraction is gentle and incomplete. Thus, the walls of the atria are thin because they are not involve in blood pumping. The ventricle on the other hand has thick, muscular wall because it has to pump blood out of the heart through strong contractions and it thus generate higher blood pressure. The left ventricle is even thicker than the right ventricle because it has to pump blood out to the greater parts of the body while the right ventricle only pump out blood to the lungs.
Answer:
Absorben o excretan agua salada para mantener la homeostasis.
Explicación:
La regulación hídrica y salina en peces de agua dulce y salada se realiza según las condiciones ambientales. Los peces pueden pasar mucha orina muy diluida en la que hay menos solutos o sales, y logran el equilibrio de electrolitos en el cuerpo mediante el transporte activo de sales a través de las branquias. En un ambiente marino hipertónico, los peces de agua salada comienzan a beber agua de mar y mantienen el equilibrio electrolítico mientras excretan el exceso de sales a través de sus branquias y su orina.
The process of dissolving two organic molecules in a polymer and recombining the water molecules to create new monomers is known as hydrolysis.
<h3>What is hydrolysis?</h3>
The molecule is broken in a hydrolysis reaction involving an ester bond, such as the one between two amino acids in a protein. As a result, the water molecule (H₂O) splits into two groups: one that forms a hydroxyl (OH) group with the remaining hydrogen proton (H+) and another that transforms into a carboxylic acid.
Practically speaking, hydrolysis refers to the process of separating compounds when water is present.
Condensation, which is the process by which two molecules combine to produce one bigger molecule, can also be thought of as the opposite reaction to hydrolysis. The outcome of this reaction is that a water molecule is ejected by the larger molecule.
The three primary hydrolysis processes are
- Acid hydrolysis.
- Base hydrolysis.
