D) Ecological systems often remain in balance if only one factor is altered.
Ecological system can affect one another regardless of how small or great the factor that was altered. This can have gradual and insidious effects on the ecosystem. <span>Ecosystem is
encompassing all the life on earth in the physical environment that
supports it. An ecosystem involves both the biological (plants, animals,
human beings) and non-biological (land, water, soil, and atmosphere)
community which interacts as a system. More importantly, the living
things are very dependent on the abiotic community since it cannot
survive by itself.</span>
Active transport. it's the only method of transfer of material that is again concentration gradient
Anaerobic respiration is the process by which some organisms produce energy in the absence of oxygen. Instead of oxygen, organic and inorganic molecules are used as electron acceptors. One example of anaerobic respiration is fermentation.
In latic acid fermentation, one molecule of glucose undergoes glycolysis to produce two molecules of pyruvate. The two molecules of pyruvate then undergo fermentation to produce two molecules of lactate. The lactate will be transported to the liver. The lactate can be reconverted to pyruvate and utilized for energy. Latic acid fermentation occurs in the muscles.
Answer: I would think A but get a second opinion to be 100% sure, okay.
If the question were why can’t a mutated RAS gene stop uncontrolled cellular division/cancer I could easily answer the question. So if you also need that answered I could just saying.
