Some genetic mutations can be completely harmless, while others are life-altering. Mutations happen when DNA is copied incorrectly. This causes an irregularity in the DNA. Mutations are permanent changes to genetic material that can be passed on to offspring. These changes happen randomly and can occur in any type of gene. While some mutations are not harmful (hazel eyes, for example), many mutations have harmful effects on health.
Answer: 3 Calories of heat will be required by silver to raise the temperature to 1°C.
Explanation: Specific heat is defined as the heat required to raise the temperature by 1°C for 1 gram of substance.
Mathematically,
where,
q = heat required = ? Cal
m = Mass of the substance = 50 g
c = Specific heat of the substance = 
= Change in the temperature = 1°C
Putting values in above equation, we get:
Answer:
Plate Tectonics
Explanation:
The theory of plate tectonics states that the Earth's solid outer crust, the lithosphere, is separated into plates that move over the asthenosphere, the molten upper portion of the mantle.
Answer:
3. diffusion, because molecules are moving from a high concentration(A) to a low concentration(B)
