The correct answer is: D. breathing
Lymphatic system is an open system that does not have a central pump (such as heart in the circulatory system), so the flow of the lymph is different than blood flow. Transport and movement of the lymph are slow and sporadic. Lymph flow occurs thanks to:
• peristalsis – contraction and relaxation smooth muscle tissue,
• valves- so that lymph doesn’t flow backwards along the vessels
• contraction of adjacent skeletal muscle .

A hypothetical collection of all the possible alleles in a population gene pool . Thus correct option (C).
A gene pool is the collection of all the genes (including alleles) found in a population or species that is capable of reproduction. A big gene pool has a wide range of genetic diversity and is more resilient to environmental stresses.
Primary gene pool, GP-1 is another name for it. The crop species itself, as well as its cultivated races and any wild or weedy spontaneous races are all included in the main gene pool, which is akin to a biological species in and of itself.
All the genes present in a population make up the gene pool. Any population might be included here, including frogs in a pond, trees in a forest, or residents of a town.
