A woman whose hemoglobin S levels are less than 1% has a brother with sickle cell disease and both parents have been diagnosed a
adoni [48]

Answer:

The correct answer is: she won't have children with the disease because for this particular condition to appear, both parents need to have the trait and she doesn't have it.

Explanation:

Sickle Cell Disease is a condition that <u>affects the red blood cells,</u> since the hemoglobin (the protein inside the red blood cells that carry oxygen and carbon dioxide) is abnormal. This condition <u>produces anemia</u> and may lead to higher chances of bacterial infection and strokes.

Sickle Cell Disease is a genetic condition that is <u>inherited in a </u><u>recessive</u><u> way</u>: this means that for someone to have it, both parents must have the trait for the condition.

cupoosta [38]

These first trees had a huge importance for the other plants and for the animals, and this was because:

- they managed to change the structure of the atmosphere by consuming, using, and storing carbon dioxide, and releasing oxygen, which made the atmosphere much more suitable for life.

- they managed to influence the climate, by making it more moist, and also making the ground bellow them cooler.

- they were producing large amounts of biomass, which made the soil types much richer in nutrients, which in turn enabled more and more plants to grow.

- they were a food source of the animals.
