The density of water is greatest at 4’C
The answer would be CGATTA.
C pairs with G and A pairs with T
Answer:
allopatric speciation by dispersal
Explanation:
Allopatric speciation is a form of speciation (creation of new species) that occurs as a result of geographic isolation. This means that a part of population becomes physically separated from the initial main population. There is no gene flow between these two populations and as a result the two populations reach a high level of genetic divergence. They can no longer interbreed which means they become two different species (speciation).
One of the factors that contribute to the allopatric speciation is dispersal.
New populations evolve as result of mutation, genetic drift and natural selection.
Answer:
Hydrogen ion(H+)
Explanation
The human blood has carbonic acid and bicarbonate anion as buffer to maintain the blood pH between 7.35 and 7.45. A virtual value higher than 7.8 and 6.8 can lead to death.
Taking coffee which has a low pH will lower the pH of the blood. In order to raise the pH back to normal and lower the level of acid present in the system. The human buffering system will to take up Hydrogen ion.
