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:
Statement 'C' is incorrect
Explanation:
Enzymes (which are a <em>form </em>of proteins) have a function of regulating the rate of biochemical reactions (they're biological catalysts, meaning they speed up reactions) ₋ in this instance, the statement would be correct.
However, this is not the only<em>, </em>or as the statement puts '<em>one specific function'</em> of an protein. For example, haemoglobin (a protein) contains haem groups that bind to oxygen. In this instance, a protein's function has nothing to do with '<em>biochemical reactions'.</em>

Plasma proteins account at least 8% of the plasma, they contribute to osmotic pressure and maintain water balance in blood and tissues, other functions includes transport and enzymatic activities. Plasma proteins include albumin, fibrinogen and globulin (alpha, beta and gamma). Globulin proteins may be used to fight infections such that gamma globulin antibodies are released by the plasma during immune response.
Answer:
Placing salty water in A and distilled water in B.
Explanation:
The fastest net rate of water movement into the A-side will occur if we place salty water on that side and distilled water in the other one. The reason for this is that the A-side contains a higher concentration of solute than B. So, the water will pass the semipermeable membrane and go to the A-side to valance the concentrations on both sides. As we can see, there is an increase in the net rate of water movement into A.
Answer:
Since cells are utilized at a point or the other in the organism life we can say the general concept of life-is-cellular holds and abandon the cell membrane partitions notion
Explanation:
where the metabolic processes occur that keep the organism alive is the cellular level of an organism (the general concept of life-is-cellular)
