The bands of circular muscle structures that are located at the cuttlefish skin are most likely responsible for the changes of its outer covering. In addition, the colour cells that are present on the cuttlefish skin were estimated to be about 10 million which is why it was coined "the chameleons of the sea."
Answer:
yes, sexual reproduction leads to the selection of better individuals for a particular environment
Explanation:
Natural selection can be defined as a mechanism associated with the survival and reproduction of individuals better adapted to their environment. Sexual reproduction is able to increase genetic variation, which is the primary source on which natural selection works. In consequence, individuals that exhibit an evolutionary adaptive phenotypic variant will have more chance to survive and to reproduce than those individuals with other less adaptive traits, thereby leading to evolution of the population and tending to optimize phenotypic variants for particular environmental conditions.
