Answers
Answer:
The correct answer is ''arises from the greater splanchnic nerve''
Explanation:
The greater splanchnic nerve or great adrenal nerve, originates in the thoracic sympathetic chain from vertebral levels T5 to T9 (T10). It runs over the bodies of the thoracic vertebrae and as it descends it becomes more anterior. It enters the abdomen crossing the diaphragmatic pillar and ends at the celiac plexus. The upper part of each celiac ganglion continues with the greater splanchnic nerve. The collateral or prevertebral ganglia innervate the abdominal and pelvic organs and viscera. The celiac ganglion receives preganglionic fibers from T5 to T12 and innervates the stomach, liver, pancreas, gallbladder, small intestine, spleen, and kidneys.

the relationship between biomass and primary productivity is that _____. see concept 55.2 (page)
Answers
The relationship between biomass and primary productivity is that biomass represents the accumulated organic matter produced through primary productivity.
Biomass refers to the total mass of living organisms or organic matter in a given area or ecosystem. It includes the mass of plants, animals, microorganisms, and their accumulated organic materials.
Primary productivity, on the other hand, is the rate at which energy is captured and converted into organic matter through processes such as photosynthesis (in plants, algae, and some bacteria) or chemosynthesis (in certain bacteria and archaea). It represents the production of organic compounds by autotrophic organisms.
The relationship between biomass and primary productivity is that primary productivity directly contributes to the accumulation of biomass. As primary producers (such as plants) carry out photosynthesis, they convert energy from sunlight (or other sources) into organic molecules. These organic molecules serve as building blocks for the growth and development of organisms, resulting in an increase in biomass.

A. Right ventricular hypertrophy
B. Left ventricular injury
C. Left ventricular hypertrophy
D. 1st degree AV nodal block
E. Right ventricular injury
Answers
The given ECG information is suggestive of Left ventricular hypertrophy (LVH)
ECG: An electrocardiogram (ECG) is a test that records the electrical activity of the heart. ECGs are painless, and they are carried out on an outpatient basis. This examination is used to identify abnormalities in heart rate and rhythm, as well as to diagnose heart diseases. The electrical activity of the heart is recorded by placing small electrodes on the chest, arms, and legs during an ECG test.
P-R Interval: The P-R interval is the time taken for an electrical impulse to move from the sinus node to the ventricles. The P-R interval is the period between the start of the P wave and the start of the QRS complex. Normally, the P-R interval lasts between 0.12 and 0.2 seconds in length.
The QRS Complex: The QRS complex is a waveform that reflects the electrical activity that occurs as the ventricles contract. Normally, it lasts between 0.06 and 0.1 seconds in duration. The QRS complex should be mostly positive in lead I, with the QRS complex in lead II being mostly positive. The voltage of the QRS complex should be between 0.5 and 1.5 mV.
Left Ventricular Hypertrophy (LVH): Left ventricular hypertrophy (LVH) is a thickening of the heart's left ventricle. This thickening is caused by an increase in the size or workload of the heart muscle. LVH may be caused by a variety of factors, including hypertension, aortic valve stenosis, and other conditions. LVH can result in an abnormal ECG pattern, which is characterized by a prolonged QRS duration, leftward axis deviation, and an increased R wave amplitude in the left precordial leads.
The P-R interval is 0.18 seconds, the QRS complex is 0.09 seconds, the QRS voltage is 1.5 mV, the S-T segment is 0.2 mV, and the MEA is -100 degrees.
Therefore, the given ECG information is suggestive of Left ventricular hypertrophy (LVH).
