Answer:
The correct statements are that the first calorimeter is reliable but not valid, and the second calorimeter is valid and reliable.
Explanation:
The first calorimeter is reliable as the reading demonstrated by it is similar when each time the experiment is performed, however, the result attained is not correct, though it is reliable. On the other hand, the second calorimeter is both reliable and valid, as it is demonstrating the accurate results from time to time. This is valid as it is providing a similar result as that of the original readings.

Answer:
Free Ribosomes
Explanation:
This is produced by the free ribosomes in the Cystosol ( thst is bounded by membrane,not attached to the endoplasmic reticulum), They are concerned with the synthesis of proteins to be used within the cystosol that is not to be exported out of the cells.
Hexokinase produced is important in glycolysis because it phosphorylated glucose to glucose -6-phosphate, increases its polarity thus reduced the metabolic process within the cell preventing glucose from leaving the cell( due to increase polarity which is restricted by the cell ,membrane.) thereby increasing the efficiency of process of Glycolysis.
