An insertion mutation occurs when an extra nucleotide is added to the DNA strand during replication. This can happen when the replicating strand "slips," or wrinkles, which allows the extra nucleotide to be incorporated (Figure 2). Strand slippage can also lead to deletion mutations. I’m not sure if this right but I tried
Answer:
limiting factor
Explanation:
In an ecosystem, certain factors hinder the growth or abundance of the population of organisms. These factors are called LIMITING FACTORS. Limiting factors, which can be biotic, food, drought, predation, disease etc, are factors that inhibits a population of organism from becoming enlarged. There are two types of limiting factors viz: density dependent (depends on size) and density independent (not dependent on size).
This is the case of a drought that dries up the stream that inhabits a population of salamanders. The drought causes the unavailability of water, which will ultimately have an effect on the growth of the salamander population. Hence, the DROUGHT is considered a LIMITING FACTOR.

The main layers of Earths interior are the inner core, the outer core, the mantle and the crust.
<h3>What is the indirect evidence that helped us determine the layers?</h3>
Use of seismic waves is the indirect evidence that helped us determine the layers. When earthquakes occur they produce seismic waves.
The flow of matter occurs by convection. The dense crust subducts back into the mantle exert forces on crustal plates that then move, producing tectonic activity.
So we can conclude that The main layers of Earths interior are the inner core, the outer core, the mantle and the crust.
