Answer:
The Weight
Explanation:
Even know it has the same volume does not mean it has the same mass and weighs the same with the items inside the box. Most likely, that the Items inside the box are heavier then the first box Max moved.
The fact that CO2 is released from oceans due to further rise in temperature is an example of a negative feedback.
A negative feedback is one in which the process that produces the feedback is interrupted. That is, the process is stopped as a result of the feedback received.
In this case, CO2 which leads to global warming dissolves in the ocean which serves a large sink for the gas. However, as the increase in ocean temperatures causes decrease in solubility of CO2, more CO2 is released leading to further temperature rise. This is an example of a negative feedback loop.

Answer:
0.72 g of the lower oxide gave 0.8 g of higher oxide when oxidised. ... Thus, 90g of lower oxide contains as much metal as 100g of higher oxide, i.e., 80g (given). Hence, 80g of metal combines with 10g of oxygen in the lower oxide and 20g of oxygen in the higher oxide.
An acid-base indicator is used to identify the presence of an acid or base. These indicators exhibit different colors depending on the solution that they are in. They are especially useful when completing titrations to determine the molarity of an unknown substance and is denoted as option D.
<h3>What is Titration?</h3>
This is done in the laboratory and involves the slow addition of one solution of a known concentration to a known volume of another solution of unknown concentration.
Acid-base indicators are used to determine the presence of an acid or base in a solution which is based on the colors seen when performing the chemical reaction.
It is used to calculate the the molarity of an unknown substance through the knowledge of the other parameters which is therefore the reason why option D was chosen as the most appropriate choice.

Answer:
Carbon is the basic compound for making of molecules in biological systems. IN growth medium, carbon sources are added to provide energy.
Explanation:
Without carbon, there would be no life on earth. Carbon molecules have the ability to form bonds that are stable with a vast number of molecules. It can also form bonds with itself. The proteins, amino acids, DNA, RNA, lipids all contain carbon molecules. Hence, it serves as the basic compound for making molecules of life. In the growth culture media, Carbon is added in the form of carbohydrates like glucose or glutamine as it provides main source of energy.
