Answer:
Los puentes de Hidrógeno, se forman por átomos de Hidrógeno localizados entre átomos pequeños muy electronegativos, cuando un átomo de Hidrógeno está unido covalentemente, a un átomo electronegativo, Oxígeno, Nitrógeno o Flúor, el átomo con mayor electronegatividad atraerá hacia si los electrones del enlace, formándose

Answer:
Hydrophobic interaction.
Explanation:
On the basis of the polarity and the dissolution of water, the molecules can be classified into the hydrophilic and hydrophobic molecules. The hydrophobic molecules can easily dissolve in the non polar solvents.
The hydrophobic interaction is important that exist between the non polar molecules. The hydrophobic interaction plays an important role in the biological system as the lipids of the cell membrane are assisted together with the hydrophobic interaction. The hydrocarbon tail is non polar molecules that contains hydrophobic interaction within it.
Thus, the correct answer is hydrophobic interaction.
The answer is A. small nutrients
Muscle tissue is comprised of groups of muscle cells, laid out in differing organizations depending on the muscle tissue type. For skeletal muscle tissue, the muscle tissue works together to push or pull the skeleton and move the organism conciously. For smooth muscle, the muscle tissue works together to push, pull, or constrict various structures unconciously. An example of smooth muscle is the muscles involved in pushing food through the esophagus. For cardiac muscle, the muscle tissue works together to pump the entire heart in tandem.
Answer:
The pathway of oxygen from lungs to the body tissues is alveoli → red blood cells → blood vessels → tissues (option b).
Explanation:
The oxygen (O₂) required by the tissues comes from the air inspired by the respiratory system. The pathway of entry of O₂ to the body and tissues is:
- O₂ from the air reaches the lungs.
- In the pulmonary alveoli, gas exchange occurs, that is, O₂ passes into the blood capillaries and is captured by the red blood cells, while CO₂ is released and passes into the alveoli to be eliminated.
- O₂ in the red blood cells travels through the blood vessels.
- The tissues receive the O₂ and a second gaseous exchange occurs at the tissue level, as they release CO₂ that will be carried to the alveoli.
Tissue oxygenation depends on the integrity of the respiratory and circulatory systems.
<em> The other options do not show the correct order in which the oxygen travels from the alveoli to the tissues.</em>
