The process that removes metabolic waste from an organism is called the excretory process. Through this process excretes are substances that are not used by the organism and thus must be excreted.
Both are exchange of gases in plants ! some differences are ....
1) respiration takes place all the time while photosynthesis happens only in the presence
of sunlight !
2) in respiration O2 is used but in photosynthesis CO2 is used !
3) starch breaks to give energy in respiration but in photosynthesis starch is formed !
Answer:
How long is the G2 phase = 6hours
Explanation:
Cell cycle undergoes various stages during mitotic cell division.
Normally cells are arrested in the resting phase G0 but as the cell division starts it undergoes G1 the growth phase then it undergoes S phase called the Synthesis phase in which the DNA synthesis occurs. Then it undergoes G2 Phase and is the shortest phase while G1 is the longest phase of the cycle. G2 normally lasts for 3-4 hours so here it may take 2.775 hours as due to presence of Thymidine the synthesis of DNA occur at high level so it contains higher levels of cellular DNA than in the G1 . so it will take 6hours G2 phase to occur.
Reabsorption occurs during the movement of substances from the proximal convoluted tubule to the distal convoluted tubule..... in the kidney
