Answer:
Modern amphibians are characterized by the flexibility of their gaseous exchange mechanisms. Amphibian skin is moistened by mucous secretions and is well supplied with blood vessels. It is used for respiration to varying degrees. When lungs are present, carbon dioxide may pass out of the body across the skin, but in some salamanders there are no lungs and all respiratory exchanges occur via the skin. Even in such animals as frogs, it seems that oxygen can be taken up at times by the skin, under water for example. Therefore, regulation of respiration occurs within a single species, and the relative contribution of skin and lungs varies during the life of the animal.
Explanation:
I believe the answer is the responding stage; which is the fourth stage of listening whee one sues feedback to demonstrate to the speaker their thoughts. Feedback is used in this stage and may be verbal or non verbal. The positive feedback; while the speaker is talking, might include, alert posture, direct eye contact, appropriate facial expressions, head nods and supportive phrases such as "go on" and 'uh-huh". After speaker talks might include requests for clarification or emphatic statements.
Endoplasmic reticulum is an organelle within a cell. It is divided into smooth and rough endoplasmic reticulum. Smooth endoplasmic reticulum is involved in synthesis and transportation of of lipids while rough endoplasmic reticulum contains ribosomes which are responsible for synthesis of proteins, therefore rough ER is involved in transportation of proteins. A few proteins are synthesized in the mitochondria and the plastids. Therefore, proteins synthesized elsewhere other than the rough ER are the Mitochondrial proteins
It’s ADH
Antidiuretic hormone (ADH) is a chemical produced in the brain that causes the kidneys to release less water, decreasing the amount of urine produced.
