Answer: chromatophores
Explanation:
The coloration of fishes is due to special cells called chromatophores. Chromatophores are referred to as the cells which produces color. They are seen in animals such as reptiles, fish,amphibians, and crustaceans.
On the other hand, mammals and birds, have a class of cells that is refered to as melanocytes for coloration. The main function of chromatophores is simply for camouflage.
Answer:

Explanation:
Mitosis creates an identical set of daughter cells to the parent cells through asexual reproduction but meiosis creates a set of sex cells that are identical to each other but not to the parent cell and this is through sexual reproduction.
<h2>Answer:</h2>
The correct answer is option A which is in prokaryotes photosynthesis takes place on the folds and in eukorytes, it is present in specialized organelles.
<h3>Explanation:</h3>
- Prokaryotic cells don't have distant nucleus and specialized organelles. in photosynthesizing prokaryotes, Photosynthesis takes place on the system of folded membranes near the cell membrane known as mesosomes.
- While eukaryotes, all organelles are fully specialized and chloroplasts are double membrane organelle for photosynthesis.
Answer: False
Explanation:
Negative reinforcers strengthen a behavior that avoids or removes a negative outcome.
Negative reinforcers are stimuli factors that influence behavior because individuals have capacity we inherited to respond to them and effects of these reinforcers have been established through records and histories of learning. Negative reinforcers are at the mercy of type of response acquired. Negative reinforcers are sources of negative reinforcements.
Unconditioned negative reinforcers
stimuli is one whose removal strengthens the choice behavior in absence of prior learning. Example includes the place of shock, loud noise, intense light.
Other times pain will occasion behavior and other response that eliminates discomfort will be reinforced.
