I'm almost 100% it is the first option
The bias conditions that must be present for the normal operation of a
transistor amplifier will be those in which the emitter-base junction is
forward biased, and the collector-base junction will be reverse biased.

The sperm are changing chemical energy into kinetic energy.
Chemical energy is defined as the chemical substance’s potential to undergo a transformation through a chemical reaction. So, this type of energy can be transformed to other forms of energy by a chemical reaction.
Kinetic energy, on the other hand, is the energy that an object (structure) possesses due to its motion.
So, in the example above, chemical energy of the glucose is used (by breaking the bonds of this molecule through the chemical reaction) for the formation of sperm’s kinetic energy (necessary for movement).
Answer:
A gene is a stretch of DNA that helps to control the development and function of all organs and working systems in the body.
Genes are passed from parent to offspring; the combination of these genes affects all aspects of the human body, from eye and hair color to how well the liver can process toxins.
