<span>Extraction of DNA is important because of many reasons. With the ability to remove DNA from an organism, scientists can observe, manipulate, and classify the DNA.
Scientists can identify genetic disorders or diseases from studying DNA.
Scientists can possibly find cures for these causes by manipulating or experimenting with this DNA.
Scientists can accurately sort organisms into classes because of DNA uniqueness. If we didn't have DNA extraction, it would be a lot harder to decide which organisms are different from each other.
Scientists can genetically engineer some organisms to produce beneficial things. A common example is that of insulin. Scientists can genetically engineer insulin production so that people with diabetes can live longer.</span>
Answer;
-Central conic vision
Explanation;
-Central vision is when our eyes focus straight ahead, allowing us to drive, read, and see details sharply.
-Central vision only covers about three degrees of our visual field, but it allows us to make very important judgments like estimating distance and understanding details in the path ahead.
Our sharpest, clearest vision is called central conic and is only about 3 to 5 degrees. This is our most focused vision where we can identify details and color
I wish i could help but im in 8th grade so im not sure about that :/
I wish you luck!

Answer:
In heterozygotic individuals, the gene for sickle cell anemia is protective against malaria.
Explanation:
Through the same mechanism that the mutation associated with sickle cell anemia produces the disease (altered hemoglobin structure), having a single copy of the mutation (that is, being heterozygotic) provides protection against malaria. This is believed to be due to the altered structure causing difficulty for the malaria parasite when it attempts to enter red blood cells as part of its life cycle.
Today, there are medications to successfully treat malaria, but it still killed 627,000 people in 2020. This represents a significant evolutionary pressure for genes that would prevent serious malarial illnesses. As malaria was and still is common in African regions, the result was a higher prevalence of sickle cell anemia in those of African descent.
