Nuclei with a higher than desired neutron-to-proton ratios tend to undergo which type of decay?

Hey there!

Nuclei with a high neutron-to-proton ratio usually undergo a beta emission.

Beta emissions, unlike some other types, is radioactive decay throughout these particles, and can have half lives like other types of exponential (usually) decay. Neutrino, along with beta rays, are coming from, or emitted from the nucleus - hence the name.

Hope this helps!

Option). eukaryotic.

Explanation:

Thermus aquaticus is a bacterium, that belongs to kingdom Monera. Bacteria are prokaryotic organisms, in which true nucleus is absent as prokaryotes lack membrane-bound organelles

Mushroom is a fungus that belongs to kingdom Fungi. Mushrooms are eukaryotic organisms, in which membrane-bound organelles, such as nucleus, endoplasmic reticulum and mitochondria are present.

Thus, the correct answer is option). eukaryotic.
