Absorption and release of heat when hydrogen bonds break and form.
<span>Male adaptations to sperm competition include relatively large testes, large sperm stores and long spermatozoa, mate guarding and frequent pair copulations. Females show no obvious morphological adaptations to sperm competition but, by controlling whether copulations are successful, they probably determine its frequency and extent. Despite this, the evolutionary benefits females acquire from extra-pair fertilizations are poorly understood.</span>
Perhaps Meiosis or Mitosis.
Endergonic reaction- reactions where chemical bonds are formed
exergonic reaction- reactions where the change in free energy is negative
The force that the pin exerts on the bowling ball is -15.0 N. This is because of Newton's 3rd law (every action has an equal but opposite reaction).
Hope this helped :)
