Answer:
The correct answer is A malate is stored in the large vacuoles.
Explanation:
During CAM malate is synthesized from oxaloacetate by malate dehydrogenase enzyme.The so formed malate is stored inside large vacuoles during night.
In the day time the guards cells of CAM plants get closed and malate is then discharged.The discharged malate is then transported into the chloroplast where the malate is converted to pyruvate and CO2.
The CO2 then enters into the calvin cycle .
Answer: People who have received radiation treatment are 15 times more likely to develop benign thyroid tumors relative to does who have not.
Explanation:
Relative risk of benign thyroid tumor = (52/2872)/(6/5055)
= 0.018/0.0012
= 15
Answer:
DNA evidence revealed the American vultures share more recent ancestor with the Storks
Explanation:
The hooded vultures that is mostly found in the African continent have a close resemblance with the American vultures and were traditionally classified to belong to the Falcon family.
However, it was observed that the American vultures shared a similar behavior with Stork which is not common to the vulture found in Africa, including the hooded vulture. The Stork and the American vulture exhibit the behavior of urinating on their legs when being overheated. When the urine gets evaporated, it helps them to cool their body temperature.
This shared behavior between the storks and the American vultures led scientists into using molecular analysis in analyzing the DNA of the hooded vultures found in Africa, the American vultures, and the stork.
Evidence from the DNA analysis later revealed that the American vultures and the storks share a more common DNA sequences than African vultures and American vultures do.
