Answer: Hurricanes (Option A)
Explanation: Hurricane is an example of density-independent factors (climate and weather). Hurricane is an environmental induced agents that can checkmate the size of a population without considering the population density of a community.
However, this process is engineered by nature, meanwhile the group of organisms have no effects on the mode of action of the agent.
Cell determination refers to the molecular process where a cell is dictated what specific cell type it will become, driven by the expression of tissue-specific genes. During fertilization, the membrane of the egg undergoes significant changes, notably in the zona pellucida, upon binding of a sperm. Furthermore, cells can follow determinate or indeterminate pathways, with the former having a predetermined cell fate and the latter a more versatile potential.
Cell determination refers to the process during which a cell's fate is decided - what type of cell it will become. This process is largely accompanied by molecular changes, particularly the expression of certain genes for tissue-specific proteins. For example, in the embryo's environment, some cells will start expressing genes that code for skin cells, hence they become destined to develop into skin cells - this is an instance of determination. These processes are regulated by precise, location-specific chemical signals.
On the other hand, during fertilization, once a sperm binds and penetrates the egg's membrane, this leads to a cascade of significant structural changes in the membrane, particularly in the zona pellucida which prevents any further penetration by another sperm. This prevents polyspermy, ensuring that only one sperm fuses with one egg.
In addition, the pathway of the cell can alter between determinate and indeterminate. Determinate means that from an early stage, the cell is destined to become a particular type of cell. Whereas in an indeterminate state, the cell is capable of becoming any cell type - a characteristic feature of stem cells.
