About lymph transport.
a) under normal conditions, lymph vessels are very high-pressure conduits.
b) lymph transport is faster than that occurring in veins.
c) lymph transport is only necessary when illness causes tissue swelling.
d) lymph transport depends on the movement of adjacent tissues, such as skeletal muscles.

The correct answer is: D) Lymph transport depends on the movement of adjacent tissues, such as skeletal muscles.

The lymphatic system is an open system which primarily consists of lymphatic vessels, (similar to the circulatory system's veins and capillaries) interrupted by lymph nodes, where the lymph is filtered. Since there is no central pump in lymphatic system (like heart in circulatory system) lymph transport, is slow and sporadic. Lymph movement occurs due to:

•peristalsis (contraction and relaxation of smooth muscle tissue),  

•valves,  

•contraction of adjacent skeletal muscle and  

•arterial pulsation.

well schools are being forced to embrace computers. unlike their "digital immigrant" teachers, these students are "digital natives", born into a world where technology is an integral part of everyday life. almost every student has access to a multitude of computers, laptops and tablet devices. it would be crazy to assume an assignment would  not be written on computer in this day and age.
