Answer:
The boiling point of water is a physical property and is equal to 0 C.
The Correct Answer is : C
Answer: Effects of Mutations
A single mutation can have a large effect, but in many cases, evolutionary change is based on the accumulation of many mutations with small effects. Mutational effects can be beneficial, harmful, or neutral, depending on their context or location. Most non-neutral mutations are deleterious.
Other common mutation examples in humans are Angelman syndrome, Canavan disease, color blindness, cystic fibrosis, Down syndrome, Duchenne muscular dystrophy, haemochromatosis, haemophilia, Klinefelter syndrome, phenylketonuria, Prader–Willi syndrome, Tay–Sachs disease, and Turner syndrome

Answer:
The plum-pudding model did not identify a central nucleus as the source of a positive charge.
Explanation:
Sir Joseph John Thomson, most popularly known as J J Thomson. He was a famous scientist who was awarded the Noble prize for Physics for his discovery of the subatomic particle, electron.
He placed his famous model of an atom which is known as plum pudding model. He proposed that the atoms are described as the negative particles that is floating within a soup of the diffuse positive charge.
But the main defect of his proposal was that it did not recognized the presence of a central nucleus as a positive charged source.
When in solid state the charged particles (ions) are NOT free to move but when in melted the ions are free to move.
Answer:
pH = 1.3
Explanation:
pH is used to measure the concentration of hydrogen ions in a solution. It can be calculated as follows:
pH = -log [H+]
Since the given solution is an acid, therefore, the concentration of H+ ions is the same as the molarity/concentration of the solution.
[H+] = 0.05 m
Substitute in the above equation to get the pH as follows:
pH = -log [H+] = -log [0.05] = 1.3
Hope this helps :)
