There are two main organs:
Kidney: purify blood from toxins, and harmful chemicals and excretes them from the body in the form of urine.
Liver: inactivates and filters toxins from the bloood and removes toxic substances that have been ingested, such as food additives, harmful minerals, toxic medications, excess hormones.
Light rays passes through the pupil in the eye and activates the neurons in the retina. The light wavers that are from the reflection of the object are transformed into neural impulses or transduction then action potentials are released when electrical charges are sent through the neurons. Excitatory neurotransmitters are supplied when action potential goes to the axon terminal and the thalamus routes the neural message from the retina elsewhere in the brain. Feature detectors organize the visual projection of the object.
The correct answer is letter A. The statement above is true that when animals eat the same type of food they are categorized in the same niche. Niches are ecological communities or ecosystems where specific organisms thrive and fit. Their evolutionary processes are also a result of these different niches found within the environment.
