Answer:
fish and tetrapods are both vertebrates that have a backbone with a spinal cord. fish lived before tetrapods because their fossils are in rocks over 500 million years old.

Answer:
oropharynx
Explanation:
The pharynx, which is sometimes referred to as the throat, is the cone-shaped muscular tube that links the oral and nasal cavity to the larynx and oesophagus. The pharynx, which serves as a passage for movement of food from the mouth to the esophagus and also as an airway, is divided into three parts, namely: the nasopharynx, oropharynx, and laryngopharynx.
The oropharynx is the part that receives both air and food. It is the middle part of the pharynx (throat) found at the back of the soft palate of the mouth and also underneath the nasopharynx.
Answer:
The answer is positive reinforcement.
Explanation:
The process of recording all the daily activities helps the patient to create conscience of what he does and how these actions could potentially develop situations where the, in this case, drinking problem could come back. After a time doing it, the person creates this conscience without the need of recording it, and the therapist highlights this fact by allowing the patient to stop recording his daily activities.

Answer:
The water soluble hormones affect the target cells with least amount of interaction.
Explanation:
Hormones are the chemical messengers. These are the substances secreted by the endocrine glands. The hormones are secreted directly into the bloodstream and are carried to the target cells within the blood only.
Based on their structure, hormones are water-soluble or lipid-soluble. The lipid-soluble hormones are steroid hormones and thyroid hormones. These hormones can easily pass through the lipid bilayer of the cell membrane of the target cell. Therefore, the lipid-soluble hormones have intracellular receptors that are present in either cytoplasm or the nucleus of the target cells.
On the other hand, the water-soluble hormones can not pass through the lipid bilayer of the target cells. Therefore, these hormones have extracellular receptors on the surface of the target cells. Binding of the water-soluble hormones to their cell surface receptors triggers the production of the intracellular second messengers that finally carry the signal to the target protein or any other target molecule.
<u>Therefore, a water-soluble hormone exhibits the least amount of interaction with the target cell. Amine hormones such as epinephrine and melatonin, peptide hormones such as oxytocin are some examples of the water-soluble hormones. </u>
