The answer is; a high neutron-proton ratio
Isotopes have the same number of protons (atomic number) but differ in the number of neutrons (hence also in their mass numbers). Isotopes are named according to their mass numbers; example carbon-12, and carbon-14. Their atomic numbers remain as 6 but neutron numbers differ (6 and 8).
Answer:
In structural biology, a protein subunit is a single protein molecule that assembles (or "coassembles") with other protein molecules to form a protein complex. Some naturally occurring proteins have a relatively small number of subunits and therefore described as oligomeric, for example hemoglobin or DNA polymerase.
Explanation:

They are used in manufacturing of drugs(antibiotics ) like penicillin that is used to save lives
They are used in the production of chemicals like pesticide
They are good source of citric acid(vitamin C)
They help in the breakdown of plant fibre and allows the nutrients to be released into the soil
They are used as model research organism
The knowledge that can be gained from this is Knowledge about how genes work in vertebrates. Option D
<h3>What is genetic engineering?</h3>
Genetic engineering has to do with the procedure by which the genetic composition of an organism is modified. This is often carried out in a laboratory so as to produce new species of an organism or for scientific research purpose. We know that interaction of genes is determined by Mendelian genetics and the patterns of inheritance have been the constant subject of study.
As such, if a Zebrafish have been genetically engineered to glow in the dark, the knowledge that can be gained from this is knowledge about how genes work in vertebrates. We know that fish is an aquatic vertebrate because it possesses back bone as does other vertebrates (presence of vetebral column).

Answer:
The correct answer is - The area has more soil to support complex plants. The competition decreases the pioneer species role.
Explanation:
Pioneer species are the initial species of organisms such as lichens and moss. These species appears in disturbed land where they break the rocks and at that time of their introduction to the area, there is enough amount of nutrition for their growth and survival.
After establishing the complex plant species these pioneer species are decreased due to the competition for the resources but due to enough soil and complex structure of the new plant species, they get very few minerals and other nutrition.
