<u>Answer</u>:
Concave shape of the wave rock is a physical evidence that supports the evolution of earth due chemical weathering
<u>Explanation</u>:
It is the best physical evidence of collection in the earth’s evolution. The earth surface is 2.7 billion years old, also the basis for formation of Australian continent formation. The wave rock is formed by weathering of the surrounding area, which helps in proving the deposition part, as the wave rock was below the ground, occurred due to deposition of rock years over years. It is made from very tough material from its surrounding. The weathering reduced the surrounding terrain, while the bedrock remained to witness for the history.
C because it has to have lots of radiation
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.
