I believe the correct answer is D.
My reasoning for this conclusion is that coyotes from various groups would have encountered diseases and potentially developed immunity (for those that survived), allowing them to migrate to other coyote populations where those individuals may introduce the illness.

In a organism, the brain directs the body how to respond to stimuli from the environment. in a cell, this function is performed
garik1379 [2080]
In eukaryotic cells, the nucleus is an enclosed structure by a membrane that holds the genetic information, which is activated when cells receive external signals (such as environmental changes). This genetic information consists of genes that respond to cellular signaling. For instance, transcription factors that reside in the cytoplasm become activated upon receiving signals from cell membrane receptors that bond with particular signaling molecules. Following this, those transcription factors move into the nucleus to engage with specific DNA promoter regions to initiate the transcription of target genes that can react to environmental stimuli.

What is the difference between lycopodium and equisetum
s2008m [2378]

Lycopodium is part of a group of plants known as fern allies. They are primarily non-flowering plants characterized by their extensively branched structure, featuring small and simple, needle-like leaves that densely cover the branches and stem. In contrast, Equisetum, commonly referred to as horsetail or snake grass, resembles a horse's tail and is the sole surviving genus within the Equisetaceae family, known for vascular plants that reproduce using spores instead of seeds.
