Hello. You forgot to add the model needed to answer a question. The model is attached below:

Answer:

Noncoding sequences are removed from a newly synthesized RNA molecule

Explanation:

Step 2 of the process shown in the figure below refers to the formation of the pre-mRNA, which is the first molecule formed in the transcription process. The pre-mRNA is not ready for use and will need to go through some biochemical processes that will transform it into an mRNA molecule ready to be used.

The most important process that occurs right now is the removal of non-coding sequences from the pre-mRNA. These sequences can be considered "garbage" and will have no use in the protein formation process.

How does water affect metamorphic processes?

KIM [24]

D. It can have elevated concentrations of dissolved substances.

Explanation:

Water in a metamorphic process can cause elevated concentrations of dissolved substances which in turn increases the rate of the metamorphic process.

Metamorphism is a change in the mineral composition of rock in the presence of temperature, pressure and water.
Water increases the rate of metamorphic processes because they dissolve substances.
Minerals in a solution reacts faster than the ones in solid state.
This lowers the activation energy for driving metamorphic transformation of minerals from one form to another.

Hellooo again. can someone answer these two for me please? (number 1 and 2 obviously)

Tomtit [17]

Answer:

1) the independent variable would be the type of treatment so underline treatment 1 and 2. The dependent variable would be the seed Yield so circle where it says Seed Yield (g/m2)

2) Yes, the bacterial treatment did have for because based on the results, the seed yield increased when putting the treatment. You can tell that with treatment 2, it was the one that had a better effect.

An X-linked gene produces spots on some platyfish. All platyfish have an autosomal repressor that inhibits the expression of the

Svetach [21]

Answer:

The correct answer is - The Dobzhansky-Muller Model.

Explanation:

The Dobzhansky- muller model is a model that explains about how the natural selection influences speciation or reproductive isolation in a specific process when hybridization takes place between 2 species of an organism.

The offspring that produce through this process is an incompatibility with other species of origin. In the given question, spotted platyfish that arise due to the X linked gene exhibits the Dobzhansky-muller model.

Thus, the correct answer is - The Dobzhansky-Muller Model.
