Answer:
Many of the parasitic invertebrates like worms are hermaphroditic.

A hermaphroditic organism can be described as an organism that has bole male and female gametes and can produce both female and male reproductive organs. In animals like snails and worms, hermaphroditism allows either partner to become male or female. While many of the other organism can undergo self-reproduction.
Hermaphroditism can also be seen in plants mainly the angiosperms.
In humans, the people possessing this quality are called intersex humans.
Answer:
Phenotypic plasticity
Explanation:
Humans have evolved over thousands of years to adapt to various environmental changes. For example, when we are in an environment that requires certain level of adaptation our off spring often formalizes epigenetic traits that lows them to overcome small changes in the environment. Over time certain genes that are turned on may remain on and eventually the ones that are off remains off. This give rise to some genes that "don't work" after millions of years of such evolution we end up with a complex genome with more DNA than "working genes".
Answer:
Ocean-Continent Convergence
Explanation:
The answer is apex and base. To simplify, the apex of the heart rests on the diaphragm and from its base, the great vessels emerge. In addition, blood vessels that are nearer to the pumping heart and must enlarge to endure pressure variations are named elastic arteries and foramen ovale permits blood to pass from the right to the left atrium, therefore avoiding to pass the fetal lungs.
