This statement is true. Early land animals indeed had gills as well as lungs. It is generally known that amphibians breathe through their skin, like how the lungs needed the skin for its respiratory. Fish have gills for breathing while mammals do have their nasal cavity and lungs for their gas exchange.
Answer:
They are smaller than blood capillaries.
Explanation:
Lymphatic capillaries drains the extracellular fluid present between the cell spaces. The fluid is known as lymph as it enters the lymph capillaries. These capillaires drains into lymph vessels that drains to lymph nodes and lymph ultimately enters the venous circulation.
Lymphatic capillaries are slightly larger than blood vessels and these capillaries have close ends. The walls of lymph capillaries are made up of endothelial cells. The endothelial cells overlap in lymph vessels and when the pressure in ECF is greater these cells move and create a sort of gap for the movement of ECF inside the lymph capillary but when the pressure inside the capillary is greater these cells again overlap and does not allow the lymph to move outside of capillary. Thus lymph capillaries only allow the ECF to enter the capillary but does not allow the lymph to go out from capillary. Lymph capillaries have greater internal pressure than blood vessels.
The development that belongs at the end of Cherie's timeline is <span> genetic engineering. This is because all the topics in her timeline involve the study, discovery, and development of the human DNA. The last part should include the scientific breakthrough called genetic engineering which allows us today to modify the genetic makeup of organisms to produce desired results.</span>
