The first one: A mutation may cause a change that codes for the same amino acid. It is not possible (or likely) that the transcription will skip over the mutation. Mutations, especially large frameshifts, are important. It does not matter how much proteins are replicated. A mutation in the DNA sequence will affect the mRNA.
<span>Ecosystem is where a group of living organisms are associated with its environment factors such as minerals or any non-living elements. These organisms and it's environment are in linked with each other through the cycles of energy and flows of chemical to each of them.</span>
Answer:
- mountainside: temperature extremes have more influence
- beach: wind and waves have more influence
Explanation:
It depends on what you mean by "factors that control weathering" and where the beach and mountain are located.
If we assume that the rock on the mountain is at a place that has seasonal snow, and the beach is in a temperate climate, then we can make these observations.
The rock on the mountainside will be "weathered" by freezing and thawing, and by plant growth (roots). These will tend to enlarge any cracks in the rock, breaking it apart. While the mountainside may be windy, that wind may not carry particles that would tend to erode the rock surface.
__
The rock on a beach will be most affected by wave and water action, tending to smooth any exposed surface. Freezing and thawing action is less common, due to the moderating influence of the water on the local weather. In some cases, plant growth may also be a factor. Wind may pick up beach sand, further tending to smooth any exposed surfaces.
C is the correct answer because
1. producer creates its own food
2. consumer eats producer so it gets energy
3. consumer or producer die giving way for decomposers

The methylene blue reduction test is a test commonly used to estimate the microbial load of a milk sample and as a result, examine the quality of the milk.
The principle of this test is that methylene blue is a dye which loses its colour in the absence of oxygen. Bacterial metabolism can cause the depletion of oxygen in the milk, therefore the methylene's reduction rate is connected to the presence of microorganisms in the milk.
As a consequence, if the tubes were not sealed tightly, then oxygen will enter the tube and the dye's colour will diminish, giving a false result concerning the presence of microorganisms in the sample.
