The correct answer is bioprospecting.
Explanation:
I got the question correct.
The Lokiarchaeota cell is one of the only ones they have yet to find out stuff about. Scientists also need to know about it because it is apart of our body and maybe sometimes they can cause infection in the body. Scientists need to know if it could lead to to some of the biggest infections ever. (I rlly Hope this helps you)

Explanation:
In mammals, the contraction of the heart muscle is caused by pacemaker cells localized within the sinoatrial (SA) node. These cells rhythmically generate slow electrically-induced action potentials due to their slow rate of depolarization. The pacemaker cells generate the action potentials that propagate through the heart and trigger the contraction of myocyte cells (i.e., myocytes simply conduct the action potential waves). The slow depolarization of pacemaker cells occurs during diastole, i.e., during the period of relaxation of the heart muscle.
The correct order of structures is mouth, oesophagus, crop, stomach(proventriculus), gizzard, intestine, and anus.
<h3>The digestive tract of birds</h3>
The digestive tract of birds starts from the mouth and ends at the anus.
As the food enters the oesophagus through the mouth, it is pushed down to the first stomach called the proventriculus.
Hydrochloric acid, mucus and a digestive enzyme, pepsin, are secreted by specialized cells in the proventriculus and start the process of breaking down the structure of the food material.
Food substances that are hard to digest are transferred to the gizzard. Nutrients are absorbed in the intestines and undigested food substances are removed through the anus.
