The atomic number of an isotope is the number of protons it contains, whereas the mass number is the total mass of the nucleus, which is the combined number of protons and neutrons in the nucleus. To find the number of neutrons, you must therefore subtract the atomic number of the isotope from the mass number of the isotope. 
<span>In the above example, the atomic number is 8 and the mass number is 18. This isotope is known as O18. The number of neutrons in the isotope is: Mass number - Atomic number = Number of neutrons

The constant turnover of body tissues requires the ______ supplied by carbohydrates, proteins, and lipids
Lera25 [3.4K]

The constant turnover of body tissues requires the <u>chemical energy </u>supplied by carbohydrates, proteins, and lipids.

<h3> What is Chemical energy?</h3>
  • The bonds of chemical molecules contain energy.
  • Exothermic reactions are those in which chemical energy is released during the reaction, frequently in the form of heat.
  • Some of the heat energy needed for a reaction to continue can be stored as chemical energy in newly created bonds.
  • The body transforms the chemical energy in food into heat and mechanical energy.
  • At a power plant, coal's chemical energy is transformed into electrical energy. Through the process of electrolysis, the chemical energy in a battery can also generate electricity.

How does the modern theory of evolution explain the loss of vestigial organs? How does the modern theory compare with Lamarck's
Rzqust [24]

Answer:

Modern theory of evolution explains that "organisms change over time as a result of changes in heritable physical or behavioral traits". Hence this change suggests the loss of vestigial organs.

Explanation:

  • Vestigial organ are those which do not have any function but is present in our body.
  • According to the modern theory the genetic and physical appearance changes along with the adaptation in environment by the organism.
  • So if the organ looses its function in order to sustain and adopt in the changing environment then they become vestigial and slowly disappear.
  • This is the common example for the Lamarck's theory of "use and disuse".
