Sickle cell anemia is a recessive trait (aa) which causes a red blood cell disorder in which there aren't enough healthy red blood cells to carry oxygen to the body. Individuals with the genotype A have normal red blood cells. These individuals who are heterozygous
for the tralt usually have no symptoms of sickle cell disease, but carry the sickle cell trait and can pass it on to the offspring,
However, those individuals who carry the sickle cell tralt have some protective advantage against malaria, making this a common
genotype in malaria prone areas. The graph illustrates the frequencies of two genotypes, MA and Aa, over many generations. Select
ALL the conclusions you can draw from the graph provided.
A)
There appears to be random mating between genotypes.
B)
There is no selective advantage for one genotype over another
C)
This graph probably represents a population in a malaria-prone area.
D)
The population reached equilibrium for these traits at about generation 35.
E)
Sickle cell disease has died out of this population and will most likely not
return

the answer is:

carbon dioxide

only about ten percent of the energy at one trophic level is passed on to organisms at the next trophic level. the remainder of the energy is used in life processes or lost as heat.

answer and explanation;

volcanic rocks are igneous rocks which form from lava, molten rock which has been thrust out of a volcano onto the surface of a rocky body such as an asteroid, planet, or dwarf planet.  

plutonic rocks are igneous rocks which form from subterranean chambers of molten rock or magma. plutonic rocks make up the base of continental crust as well as oceanic crust. their slow rate of formation causes them to be coarse grained since there is plenty of time for large crystals to form before the magma solidifies into rock.

the textural difference is that plutonic rocks are more coarse grained than volcanic rocks. plutonic rocks are coarse grained while volcanic are fine grained ; glassey or fragmental. since fine and coarse are adjectives the decision as to whether a rock is fine or coarse grained is generally made on the bases of whether or not the individual crystals can be seen in most if the rock.
