An atom consists of an atomic nucleus composed of positively charged protons and neutral or uncharged neutrons.
Answer:
C. Both (a) and (b)
Explanation:
Hunting, destroying habitats, polluting and introducing non-native species can cause extinction.
Habitat destruction, and thus habitat fragmentation, is the major cause of declining biodiversity; the second major cause is <u>Invasive Species</u>.
The process by which a natural ecosystem can no longer support its native species is known as habitat destruction. Reduced biodiversity and species abundance result from the displacement or death of the creatures that once occupied the area. The loss of biodiversity is mostly caused by habitat degradation.
An imported organism that overpopulates and damages its new habitat is referred to as an invasive species. Even though the majority of imported species are neutral or helpful to other species, invasive species have a negative impact on habitats and bioregions, harming their ecology, the environment, and/or their economy.
The most frequent methods for invasive plants, animals, microorganisms, and other species to spread to new ecosystems are thought to be human activities like those involved in international trade and the pet trade.

The inheritance of gene expression patterns, in the absence of the initiating signal, is called Epigenetic regulation.
Epigenetic changes can be defined as inherited variations which are not present in the DNA sequence. Gene expression is regulated at different levels and not merely in response to DNA modifications. Examples of epigenetic control include DNA methylation, histone deacetylation and mi-RNA expression.
Epigenetic mechanisms add an adaptive layer of control in the regulation of gene expression that allows an organism to adapt to a dynamic environment.
Epigenetic regulation increases the functional intricacy of deoxyribonucleic acid (DNA) by changing chromatin structure, nuclear organization as well as transcript stability.
