magine that some members of an aquatic species of motile, photosynthetic protists evolve to become parasitic to fish. They gain
the ability to live in the fish gut, absorbing nutrients as the fish digests food. Over time, which of the following phenotypic changes would you expect to observe in this population of protists
The protists are known to have the chloroplast inside there bodies in order to have there own food mostly prepared by themselves in the given manner, since they no more require the chloroplast to produce there own food thus the presence of the pigment will no use to them. And thus after the level of evolution that occurs inside them we do not expect any form of pigments to be found inside there bodies.
Some protists such as some members of an aquatic species of motile possess an organelle called chlorophyll which helps in capturing the energy from sunlight to produce food for the organism in the presence of water and carbon dioxide. Since this aquatic species of motile now evolved to become parasitic to fish and now obtains nutrition from fish gut without relying on photosynthesis, the most likely phenotypic changes to expect to observe in this population of protists is the loss of chloroplasts.
Lunar Eclipse: The moon moves in an orbit around Earth, and at the same time, Earth orbits the sun. Sometimes Earth moves between the sun and the moon. When this happens, Earth blocks the sunlight that normally is reflected by the moon. (This sunlight is what causes the moon to shine.)
