The correct answer is B. Genetics
Explanation:
In health, a risk factor is a variable that can make a patient more likely to develop a disease or condition. Additionally, some of these factors can be controlled or changed by the patient, while others cannot be modified. Factors that can be controlled include stress, diet, weight, alcohol intake, and habits. This does not apply to factors such as age or genetics, for example, in the case of genetics, this is determined by the genes of each parent when a human being is formed, and therefore there is not any way to change this; although factors such as diet, stress, or smoking affect the expression of mutations in genes. Thus, the risk factor Jack has no control over is genetics.
Noah's principle is a concept that comes from the Biblical story found in the old testament where God gave Noah instructions to build an ark to save him and his family .

A complex assemblage of animals, plants, and their environment through which materials and energy move is known as ecosystem.
<h3>What is a ecosystem?</h3>
All the organisms that live in an ecosystem are present, along with their physical surroundings. Through energy flows and nutrient cycles, these biotic and abiotic components are interconnected. Plant tissue absorbs energy from the system through photosynthesis. Animals contribute significantly to the flow of matter and energy through the system by eating plants and one another as well as.
Additionally, they affect the biomass levels of the microbial and plant communities. Decomposers help to promote nutrient cycling by transforming nutrients stored in dead biomass back into a form that can be easily utilized by plants and microbes. They do this by consuming dead organic matter and releasing carbon back into the atmosphere.
