Answer:
Option A is the answer
Explanation: I took the test
Answer:
True
Explanation:
The formation of urine in the human body is done by the excretory system and the part of the excretory system that involves the formation of urine is known as the urinary system.
The nephron present in the kidney is the functional unit which filters the blood and excretes out the waste material.
The structure of nephron reabsorbs the important solutes like sodium ions and water from the blood and excrete out the waste product as the urine. The collecting tubule then again reabsorbs the water and the important solutes which are considered a part of the urinary system and release waste material into the urine.
Since the waste material is released into the kidney therefore true is the correct answer.
Answer:
Regeneration of RuBP
Explanation:
The Calvin cycle (C3), which is also referred to as the light independent reaction occurs after the light stage of photosynthetis. It occurs mainly in three stages viz: Carbon fixation and reduction stage has been mentioned in the question
The third stage is the regeneration stage.
After the synthesis of 6molecules of G-3-P which requires NADPH and ATP as sources of hydrogen and energy respectively, one of the G-3-P molecules is exported out of the cycle in order to contribute to the formation of other compounds (glucose molecule). The remaining 5molecules of Glyceraldehyde-3-phosphate is then used in a series of chemical reactions to regenerate the CO2 acceptor, RUBP, which will then continue CO2 assimilation for the Calvin cycle to continue. The NADP+ and ADP molecules produced during the reduction of PGA to 3GP will return to the light stage to continue the process as well.
Girls are the least of getting into trouble
DNA replicates itself, so no, unlike what it may seem, parent organisms do not loose their DNA. Before the fecundation process, a cool process similar to miosis happens, it is called meiosis. During meiosis the parent chromosome will duplicate it self and break down each of its 46 chromosomes into 4 different new formed cells, which will become the sperm and egg cells. Each of these egg or sperm cells will be different from eachother, which is how you get siblings that don't look alike, however they will contain a copy of the parent's genetic information.
In conclusion;
In the creation of offspring, the copy of the parent's DNA breaks apart into 4 different pieces which will form sperm or egg cells.
