Answer:
See the eplanation below, please.
Explanation:
In sickle cell anemia, hemoglobin has the form of rigid bars inside the red blood cells, causing them to adopt sickle shapes being not very flexible. These cells can block blood vessels, stopping the flow, causing oxygen to not reach the tissues.
The cause of this anemia is due to a genetic mutation (there is a substitution of thymine for adenine in the beta globin gene, located on chromosome 11), generating Hemoglobin S with a decrease in oxygen binding.
DNA helicase is the enzyme that opens the double helix
Transpiration-Plants put water back into the atmosphere through the process of transpiration.
Water is carried through plants from roots to small pores on the underside of leaves, where it changes to vapor and is released to the atmosphere. Transpiration is evaporation of water from plant leaves. (From Usatestprep)
Erosion is the answer. It's probable that the natural process of erosion caused the exposed layers of rocks.
Fungi produce spores that will combine with the opposite mating type (sexual) or germinate itself (asexual)
