Take a bowl of ice, put it out in direct sunshine and note its temperature after every 05 minutes. What type of change in its temperature, do you observe? How much time will it take to melt completely? Now put the same water on a stove and note down its temperature after every 30 seconds. What type of change in its temperature, do you observe now? How much time will it take to boil? Explain your observations with the help of time and temperature chart. (Perform this experiment on a sunny day)

gregor john mendel is known for study of inheritance in pea plants. he used garden pea plant for his study, having alternative traits for various characters. he performed cross-breeding in pea plants to check how characters are transmitted between parents to offspring, such as cross between pure tall and pure dwarf plant. mendel studied the inheritance patterns in pea plants for various generations.

thus, the correct answer includes options and f).

digestion

it excretes wastes

answer: the correct option is d. enzyme

lactase and carbonic anhydrase are the examples of enzymes.

lactase is an enzyme, which is present in the small intestine of mammals. it in the digestion of the disaccharide, lactose ( milk sugar) by converting it into two monosachharide, which are glucose and galactose.

carbonic anhydrase is present in the red blood cells. this enzyme plays significant role in the transport of co₂. it in the conversion of co₂ and h₂o into carbonic acid, which is then dissociated into bicarbonate ions and hydrogen ions.
