Lymph traveling from the left arm would enter the venous circulation via the thoracic duct.
<h3>
What is thoracic duct?</h3>
- The largest lymphatic channel in the body's lymphatic system is the thoracic duct, commonly known as van Hoorne's canal.
- Adults have an average length of 40 cm, and their abdominal origin is about 5 mm wide.
- The thoracic duct runs from the root of the neck to the twelfth thoracic vertebra.
- The thoracic duct enters the posterior mediastinum, remaining to the right of the vertebral column, by ascending via the diaphragm's aortic hiatus.
- At the T7 vertebral level, it runs posterior to the esophagus before crossing over to the left side of the thorax at the T5 vertebral level.
- The primary lymphatic channel for the return of chyle/lymph to the systemic venous system is the thoracic duct.
- It drains lymph from the left side of the face and neck, left hemithorax, left upper limb, and both lower limbs.

Following are the best conditions or examples for the natural selection to occur:
• More organisms are born than can survive.
• Organisms vary in their characteristics, even within a species.
• Differences in reproduction and survival are due to variation among organisms.
Hope so, this answer will help you.
The answer is difference in density. We know that the high central density suggests the earth must be rich in nickel and iron and that much of the core must be liquid. This lower-density air then rises and is replaced by cooler, higher-density air. The result is atmospheric circulation that drives the weather and climate through redistribution of thermal energy.
Answer:
False. They are not considered a population.
Answer:
controlled experiments
Explanation:
Experiments in which all variables are identical except for one are called controlled experiments. This where an observer tests his hypothesis by looking on changes that were brought about by one variable. The results are always dependent on one adjusted variable.
