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.

Chloroplasts are organelles that help plants convert water, energy and sunlight into food. Chloroplasts support photosynthesis by storing energy and synthesizing metabolic materials.
Since the colorblindness is located on the X chromosome, the man must have inherited his colorblindness from his mother.
<h3>X-linked traits</h3>
Women are XX while men are XY.
Also, the X chromosome in XY always comes from the mother.
Since the man is affected for colorblindness but his brother is not, it means that only one X chromosome of the mother is affected while the father can be affected or otherwise.
Assuming the father is free from colorblindness and the allele is represented by c:
x 
Thus, the man's genotype is and it comes from the mother.

Reduces water loss compared to other nitrogenous wastes but requires more metabolic energy to produce
Mammals excretes urea as the primary nitrogenous waste product. On the other hand birds, and reptiles excretes uric acid as the primary nitrogenous product. They are called uricothelics because they can convert ammonia to uric acid. Uric acid is a compound similar to purines. This is produced through a complex metabolic pathway thay cost high energy. However it has advantages such as reducing water loss.
