Answer:
— Washing with soap and water is an effective way to destroy and dislodge many microbes
Explanation:
- Soap actually kill germs on our hands, it breaks them up and removes them
- .But soap molecules have two different ends to them.
- One end is attracted to water molecules – this is called hydrophilic
- – and the other end loves oil and fat molecules – this is called hydrophobic.
- Soap is able to bind to the oils on our hands, and then mix with the water to wash all the germs away.
Using ideal gas formula (PV=nRT), you can conclude that volume directly related to the temperature. That means an increase in temperature will cause an increased volume too. Note that the temperature is using Kelvin, not Celsius. The calculation would be:
V1/T1= V2/T2
590ml / (-<span>55+ 273)K = V2/ (30+273)K
V2= (590ml/ 218K) * 303K
V2= 820ml</span>
Answer: A mutation because a change in DNA that is natural is a mutation. :)
This is called the Mass Number of the isotope of the atom.
Isotopes are different forms of the same atom. They have the same number of protons but different number of neutrons.
Carbon-12 has mass number 12 as it has 6 protons and 6 neutrons.
Carbon-14 has mass number 14 as its has 6 protons and 8 neutrons.
