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.

Difference between incomplete and complete ventilation? any 4​
Temka [501]

Answer:

Due to exchange of gases i.e. normal and abnormal.

Explanation:

The main difference between incomplete and complete ventilation is the occurrence of normal and abnormal exchange of gases. The mechanism in which the exchange of gas happens completely without any difficulty is called complete ventilation. It is the process in which the required amount of oxygen is inhaled or inspired and appropriate amount of carbon dioxide is exhaled out of the body while on the other hand, incomplete ventilation is a mechanism in which exchange of gases is not normal.

In the fish called the peacock wrasse (Symphodus tinca), females disperse some of their eggs widely and lay other eggs in a nest
Vinvika [58]

Answer:It is to ensure that a good percentage of offspring survive

Explanation: As with most organisms, there is a good chance that not all offspring will survive, due to factors such as limited resources, predation, etc. Thus certain measures have to be put into place by the parents to ensure a good chance at survival for their offspring. In this case, the eggs that are widely spread out are seen as sacrificial ones, because the parents will not be able to fully care for them and provide resources for them and the ones which were laid in the nest. They will also act as offerings for any predator on thee hunt. All of this will greatly increase the chance of survival for the eggs which were laid in the nest and will receive parental care .

You are studying a cloned line of neuronal cells that grow in culture and form synapses with a cloned line of muscle cells. Thes
murzikaleks [220]

Answer:

Explanation:

TransA can be found in the plasma membrane, while TransB is found in the cytoplasm, according to the immunofluorescence localization test analysis. There are two main varieties of serotonin transporters in the neural system when it comes to serotonin signaling.

  • An intracellular transporter that carries and delivers serotonin throughout synaptic vesicles.
  • A transmembrane transporter that prevents hyperactivity overstimulation by re-uptaking serotonin from the synapse.

Therefore, suppose we compare this signaling pathway model to the analyzed experimental test. We can vividly acknowledge that TransA acts as a serotonin reuptake transporter since it is present in the plasma membrane of nerve cells and TransB is a serotonin vesicle transporter that is present and located in the cytoplasm. As a result, the majority of TransB is speculated to be present in synaptic vesicle membranes.
