Answer:

False. When bonds are broken, energy is absorbed.

Explanation:

Atoms form bonds to seek stability, which means lower energy compared to when they were separated. This means that separating atoms by breaking bonds is not energetically favourable.

Therefore, in order to break a chemical bond we need to provide energy to the system, which makes the process endothermic (it absorbes energy).

The attached image shows an energy diagram for the H₂ molecule, showing the variation in energy during bond formation.

Which best describes meiosis?

Mariulka [41]

The right answer is It produces male and female sex cells.

Meiosis is the process of double cell division allowing the formation of gametes, or sexual cells in eukaryotic organisms. It differs from mitosis, somatic cell division, which takes place only in a time. From a diploid mother cell, we obtain four haploid daughter cells with different genetic material.
