The right answer is A. Some carry out photosynthesis...
The sea slug, Elysia chlorotica, is the first discovered animal able to use photosynthesis to produce energy. This photosynthesis is performed by the chloroplasts of its main food source, the seaweed Vaucheria litorea. They are sequestered by the digestive epithelium of the slug for several months according to a phenomenon of kleptoplasty, continuing their function of carrying out photosynthesis.
However, the chloroplasts of Vaucheria litorea have transferred a large part of their genes required for photosynthesis to the nucleus of the cells of this alga during evolution. Photosynthesis is nevertheless maintained in the sea slug thanks to the transfer of a gene necessary for photosynthesis from the kernel of the seaweed to the genotype of the slug.
The answer is C. Keeping the chemical at a constant temperature
Answer:
If there is a change in the environment, the particular species which does not manage to adapt either tries to translocate to a different habitat or it perishes. Adaptation requires a long time and does not happen overnight so if there is an option of moving out the animal adapts to do so. If that doesn’t happen we are looking at local extinction of the concerned species. This is one of the reasons why we are facing extinction of several species in our times. The rate at which we are changing the characteristics of habitats and even wiping out certain pristine habitats is leading to extinctions.
