1. Platelets help the blood to clot. Clotting stops the blood from flowing out of the body when a vein or artery is broken. Platelets are also called thrombocytes. Red blood cells carry oxygen.

2. Use of stem cells in medicine

Cell therapies would use stem cells, or cells grown from stem cells, to replace or rejuvenate damaged tissue. Scientists also want to use stem cells to understand disease and find drugs that might treat it. Embryonic stem cells could be used to make more specialized tissues that have been lost to disease and injury.

Line bc is represented by 3x + 2y =8 line ad is a represented by -3 x -2y =6 what is the relationship of line bc to line ad expl

Vlad1618 [11]

Answer:

Parallel lines

Step-by-step explanation:

Line BC:

$3x + 2y =8$

Line AD:

$-3x - 2y =6$

Adding both equations, in this case, gives us the point at which the lines intersect:

$3x + 2y-3x-2y =8+6\\0=14$

Since zero will never equal fourteen, the equation above means that lines BC and AD will never intersect. When two lines have no point in common, they are said to be parallel lines.
