Based on the table, if a space shuttle can travel 440 billion kilometers in a few seconds only, then the statement "A and B are Astronomical bodies" are correct. Why? In space travel, light travels at the speed of 300,000 km per second. It is logical that for a space shuttle to be able to travel a billion kilometers in just a few seconds, it travels at the speed of light and therefore is traveling between two astronomical bodies.
Answer:
the types of cells are Stem cell, red blood cell ,white blood cell ,platelets, nerve etc . Among this cell nerve cell is the longest cell.
In this statement it is said that there are 200 different cell but they are dependent on other cells to perform body function. It is because one cell makes substance such as protein for other cell to funtion.
Because RNA is used for making proteins however DNA is used for genetic material So it needs to be converted so it can complete its task of creating proteins.
Blood cells are produced in the bone marrow and the bone marrow is part of the skeletal system. So the answer would be skeletal system<em>. </em>
