Answer:

Explanation:

LHON (Leber Hereditary Optic Neuropathy): Is a disease that is characterized by loss of vision in young adults.

Sickle cell anemia: Is a disease characterized by production of abnormally shaped red blood cells, that is, not round in shape as normal but are 'sickle' shaped or elongated/crescent shaped.  

Both diseases are heritable But LHON is caused by mutations existing in the mitochondrion thus only inherited maternally.

Sickle cell anemia is caused by mutations in the HBB gene which produces the beta subunit of hemoglobin. It is inherited from recessive genes of both parents.

Assume that some members of an aquatic species of motile, photosynthetic protists evolve to become parasitic to fish. They gain
Elodia [21]

Answer:

c.) loss of chloroplasts

Explanation:

Chloroplasts are the double membrane-bound organelles of photosynthetic eukaryotes and serve as the site for photosynthesis. The organisms that can carry out photosynthesis make the organic nutrients and do not depend on other organisms for food.

According to the given information, the photosynthetic protists become parasite in fish and start deriving nutrition from the host. If the protists continue to survive as a parasite to fish, the chloroplasts will be rendered non-significant. The parasitic mode of nutrition does not require chloroplasts and therefore, the protists would lose the organelles over generations.

When replenishing fluids with a glucose solution, what percentage of glucose and electrolytes is most useful?
Afina-wow [57]

Answer:

6%.

Explanation:

Intravenous glucose solution contains a mixture of glucose especially dextrose and water is used for medicinal purpose. The water loss that occur during fever or any disease can be treated by the glucose solution.

Different glucose level that can be used for the treatment is 5% to 6%, 105 and 0.45 %. The administration of 5 to 6 % sugar solution maintains the balance between hyper glycemia and hypoglycemia. These reactions are activated by sympathetic division that maintains the electrolyte balance in the body.

Thus, the answer is 6%.
