Answer: ORGANIC ACIDS
Explanation:
CAM PLANTS CARBOXYLATE ORGANICS ACIDS through the addition of CO2 to PEP Carboxylase( a phosphoenolpyruvate carboxylase enzyme present in the mesophyll cells of the cytoplasm in a green plant) to produce Oxaloacetate (organic compound).
CO2 + PEP ⇒ C4H4O5 (oxaloacetate)
Oxaloacetate is then converted to a similar molecule, Malate (C4H6O5, another form of organic compound) that can be transported in to the bundle-sheath cells. Malate enters the plasmodesmata and releases the CO2. The CO2 then fixed by rubisco and made into sugars via the Calvin cycle.
Answer:
d. adding an inhibitor
c. fish that emit light
c. released
Explanation:
An inhibitor is a negative catalyst. It is usually a substance that slows down the rate of chemical reaction.
Chemical inhibitors acts in way that makes reactions drags over time.
Increasing temperature, increasing concentration and decreasing particle size all will increase the rate of chemical reaction. They make reactions proceed more faster.
When a fish emits light, it is not an exothermic reaction.
An exothermic reaction is one in which heat is released to the environment. In such reactions, heat is liberated to the surroundings. At the end of the reaction, the surrounding will have a higher temperature compared to the reaction.
We assign exothermic reactions a negative value because the sum of heat contents of products is less than that of reactants.
Answer : The atomic mass of carbon is, 12.01 amu
Explanation :
Average atomic mass of an element is defined as the sum of masses of each isotope each multiplied by their natural fractional abundance.
Formula used to calculate average atomic mass follows:
As we are given that,
- Mass of C-12 isotope = 12.00 amu
Percentage abundance of C-12 isotope = 98.93 %
Fractional abundance of C-12 isotope = 0.9893
- Mass of C-13 isotope = 13.00 amu
Percentage abundance of C-13 isotope = 1.07 %
Fractional abundance of C-13 isotope = 0.0107
Now put all the given values in above formula, we get:
![\text{Average atomic mass }=[(12.00\times 0.9893)+(13\times 0.0107)]](https://tex.z-dn.net/?f=%5Ctext%7BAverage%20atomic%20mass%20%7D%3D%5B%2812.00%5Ctimes%200.9893%29%2B%2813%5Ctimes%200.0107%29%5D)
Therefore, the atomic mass of carbon is, 12.01 amu
<u>Option 1 </u>is a suitable graph for a “constant positive velocity”.
Option: 1
<u>Explanation</u>:
Consider a car is moving with the constant velocity, the position and time graph with “constant positive velocity” of the car is represented by the graph which is in option 1. In this graph (option: 1) has the straight line with the slope. The slope in this “position - time” graph represents the “speed of the car”, the velocity is positive hence the graph is drawn positive direction. Here, the “slope of the car” less so the car moves with less speed and constant positive velocity.
