Red bone marrow belongs to the lymphatic system. While it is housed within bone all lymphocytes develop in bone marrow as well as use it as a conduit for the cells to begin circulation. Hematopoieses happens here were marrow-derived stem cells differentiate (choose what they will become) into either fully mature cells of the immune system or precursors ( will change later) that travel out of the bone marrow. Bone marrow produces: B cells, natural killer cells, granulocytes and immature thymoctyes, red blood cells and platelets.
Look up intelligent design. Intelligent design is an acceptance and understanding of both creation and evolution going together.
Fimbriae, flagella and pili are all examples of blank structures found in some bacteria.
The pH of blood if pco2 drops to 35.0 mmHg is 7.459
The pH of the blood can be calculated using the Henderson- Hasselbalch equation, which explains the relationship between acid dissociation constant pKa and pH in biological and chemical systems.
pH = pK + log ( HCO3- / ( 0.03 * PCO2 ) )
pK is 6.1 for the bicarbonate buffer system.
HCO3- = 24mm
PCO2 = 35.0 mmhg
pH = 6.1 + log ( 24 / 0.03 * 35.0 )
= 6.1 + log ( 24 / 1.05 )
= 6.1 + log 22.8571
= 6.1 + 1.3590
= 7.459
Hence, the pH of blood is 7.459
