Answer:
A) NaCl will be exported from the red blood cells by facilitated diffusion.
Answer:
the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct.

Answer:
The sequence of the nucleotides along the backbone encodes genetic information. The four roles DNA plays are replication, encoding information, mutation/recombination and gene expression.
Explanation:
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>
the answer would be B. fish
have a wonderful day
