Go to the Prenatal Testing page for more details. If one parent has sickle cell trait (HbAS) and the other has sickle cell anaemia (HbSS) there is a one in two(50%) chance that any given child will get sickle cell trait and a one in two chance that any given child will get sickle cell anaemia.
Answer:
Individuals that are well adapted to their environment will survive and reproduce
According to Charles Darwin's theory of evolution by natural selection, organisms that possess heritable traits that enable them to better adapt to their environment compared with other members of their species will be more likely to survive, reproduce, and pass more of their genes on to the next generation.
Explanation:
The empirical formula is the simplest whole number ration that defines constituent atoms in a species. The molecular formula is always a multiple of the empirical formula.
Molecule Formula = 78.0 • g • mol ^ -1 = n(12.011 + 1.00794) • g • mol ^ -1
78
N = ——————————- = 6
12.011 + 1.00794
Molecular Formula = C6H6
Answer:
D. hotter rock rises and cooler rock sinks.
Explanation:
We know that as we move <u>towards Earth's center</u>, the <u>temperature rises</u>. This rise in temperature causes rocks to melt (magma). The high temperature and melting of rocks <u>decrease the density of material </u>which makes it <u>move upward</u>. By <u>moving upward</u>, the molten rock <u>starts turning solid</u> and becomes <u>denser again</u>. Here, it <u>sinks back due to gravity</u>. This upward and downward movement of rocks due to density and temperature makes a convection cell.
PS: The formation of convection cells in Earth's interior is also the reason for plate tectonics.
