2. what is one advantage and one disadvantage of sexual reproduction? 3. what is one advantage and one disadvantage of asexual reproduction?

Sexual Advantage - more genetic variation
Sexual Disadvantage - slower reproduction rate.

Advantage of Asexual - doesn't require fertilization.
Disadvantage of Asexual - little variation, which could lead to extinction

Explanation:

advantages of sexual reproduction

In sexual reproduction, genetic information from both the parents is combined,which results in a greater chance of evolution, genetic diversity and formation of a unique individual.

disadvantage of sexual reproduction

In sexual reproduction, a suitable mate is required to reproduce and fewer offspring are produced.

advantages of asexual reproduction

In asexual reproduction offspring is produced from the single parent, a partner is not required and more offsprings are produced.

disadvantage of asexual reproduction

In asexual reproduction, genetic material is not exchanged, offspring are identical and this causes diversity to be limited.

Spontaneity tell us the direction of the reaction, but not how fast it goes. gibbs free energy brings together enthalpy, entropy and temperature in one easy formula. g = h - ts. and, finally the sign of delta g is always negative for a spontaneous reaction.
