Answer:
speciation is when one species splits off into multiple species.
In-depth answer:
Speciation can happen in 4 different ways, the first being Allopatric Speciation, where 2 groups of the same species are physically separated for extended periods of time, and when they're re-introduced, they don't breed.
Sympatric Speciation is when 2 groups of the same species aren't seperated, but form different behaviors that isolate them reproductively (the groups wont inter-breed)
Parapatric Speciation is when 2 groups of the same species are suddenly placed into a new environmental niche, and adapt in different ways to fill that niche.
Quantum Speciation is much less recognized, but it's when a new species rapidly evolves and 'buds off' from the original group
Answer:
Scientists use volcanic activity data from this area to show the relationship between volcanic activity and lithospheric plate motion. Hot Spots and Plate Tectonics: A volcanic hot-spot is an area in the mantle from which heat rises in the form of a thermal plume from deep within the Earth. Higher heat and lower pressure at the base of the lithosphere melts rock and forms magma.

Answer:
a. combine the samples and check for coagulation
Explanation:
a. combine the samples and check for coagulation
We know that hemophilia is X linked recessive disorder which arises basically due to lacking of clotting factor in the blood (Factor VIII or Factor IX). According to the condition provided if pathology is closed so doctor can not perform the specific test so only their is chance to combine the sample of patient blood with the classic hemophiliac blood sample.As here doctor is sure that the blood sample available in his hospital is of hemophiliac patients so it does not contain clotting factor. When he mix both blood and then if the blood show coagulation it means David do not have hemophilia but if after mixing both the blood sample coagulation will not occur so David may be hemophilic.
