The chemical processes that occur within a cell are affected by many factors. Optimum cell function will not occur due to the following factors: 1. These chemical processes are very sensitive to the temperature and the pH of the cell. If the cell's temperature is either too high or too low, the cell cannot function efficiently. The same can be said for a cell's pH. Enzymes are most active during a limited pH range. If the pH moves outside of this range, the cell's enzymes cannot function efficiently.
2. Cofactors and Coenzymes. Many enzymes and cell functions require additional factors and enzymes to function efficiently. If the required enzymes are not present in the cell, the cell cannot function properly.

ss7ja [257]

Answer:

Scientist 1

Explanation:

<em>The conclusion of scientists 1 is valid.</em>

Human activities such as burning of fossil fuels, agriculture, deforestation, etc. leads to the emission of carbon in the form of carbon dioxide into the atmosphere. <em>An increase in the population of a city will only lead to an increase in these activities and hence, an increase in the amount of carbon emitted into the atmosphere.</em>

Also, volcanic activities leads to the production of volcanic gases which is a mixture of carbon dioxide, oxides of sulfur, nitrogen, etc.

<u>However, an active volcano that is several miles away from the city might not be a major source of carbon in the air above a large city. The carbon dioxide produced from such volcanic activity thins out before reaching the city.</u>

When we doing strawberry extraction,why do we have to remove the air as much as possible before we seal the bag?
AlladinOne [14]

Answer:

Explanation:

Oxygen is needed to support life and some metabolic processes in microorganisms especially aerobic organism.

The presence of oxygen in the container gives them the opportunity to carry out there metabolic activities thereby enhancing there growth and multiplication.

Hence, to limit the growth of aerobic bacteria or fungi, and also to prevent the evaporation of volatile components that is available in the content oxygen is withdrawn this help extend the shelf life of the produce to be stored.
