They are herbivores which means they eat grass, mostly trees and bushes
Answer : B) In step 2, there was a chemical change which was observed in sugar.
Explanation : In A step 2 there was a physical change that was seen. By just boiling the dissolved salt solution salt was obtained. Therefore, it is a physical change. In B step 2 there was a chemical change seen as sugar solution was thickened and turned brown. It was not obtained in its original form; there was a chemical reaction that took place during sugar evaporation. As chemical change is the one where the reaction is irreversible.
Therefore only in B step 2 there was a chemical change that was observed.
Answer:
Taxol alters cytosolic calcium signaling by opening mitochondrial pores
Explanation:
Taxol is an antimitotic (i.e., cytotoxic) agent used in chemotherapy to kill cancer cells. Taxol is an antimitotic drug that has been successfully used in different types of cancer including ovarian cancer, breast cancer, pancreatic cancer, sarcoma, etc. Recently, it has been shown that Taxol may induce rapid cytosolic calcium (Ca2+) response by producing a decrease in mitochondrial membrane potential associated with the loss of mitochondrial Ca(2+). In consequence, it has been proposed that the side effects of chemotherapy might be associated with the action of cytotoxic agents such as Taxol which alters mitochondrial function and Ca(2+) signaling cascade.
