At pH 7, this enzyme's maximal initial reaction rate is 350 X 10>6 per minute of product produced with a saturation of 2–4g of substrate.
- An enzyme-catalyzed reaction has a very productive relationship between the substrate concentration and the starting reaction, but the pH of the supplied solution has a significant impact on this relationship. pH7 has the highest rate of productivity.
- The connection is roughly linear with respect to substrate concentration and pH level up to the saturation point, which in this case was attained between 2g and 4g of substrate.
- Up until the point of saturation, which in this instance is between 2g and 4g of substrate, the reaction is more productive with increasing concentration. Beyond that point, adding more substrate has no extra benefit.

Answer:
The correct answer is - option B. the cell membrane is selectively permeable, which controls the movement of materials in and out of the cell by passive and active transport.
Explanation:
The cell membrane is the most essential cell organelle that is mainly responsible for the regulation of homeostasis of the cell. It acts as a barrier between the outer environment and cell components are enclosed in the cell organelles and cytoplasm by regulating the movement of the material in and out of the cell.
This movement can be active or passive transport depending on the nature of the material as it is a selectively permeable membrane.
The correct answer is - option B.
Plants adapt to their environment in order to get the water and sunlight they need to survive in a harsh environment
A major greenhouse gas is CO2 and nearly all CO2 gasses come from fossil fuels, except for methane gas and nitrous oxide which comes from waste and are GHGs (which shouldn't be discounted).
Answer:
B
Explanation:
When the sun shines evenly on Earth, both hemispheres are experiencing either fall or spring.
Earth orbits the Sun counterclockwise and in position A the southern hemisphere is experiencing summer, so if the options are in order, the southern hemisphere is experiencing spring in position B.
