adell [148]

Answer:

B) You measure the quantity of the appropriate pre-mRNA in various cell types and find they are all the same.

Explanation:

In the above scenario, we are using the control gene and we should know about the control gene is that its expression is either at transcription level or at translation level. For this situation we should examine the pre-mRNA stage of control gene in various cells because it is control gene so it should be present in various cells.

So, the best practice is to quantify the pre-mRNA level of gene then we can effectively solve the experimental problem and find the gene expression either it is at transcription or translation level.

Which of the following events would be directly affected if a neuron had a mutation that prevented the production of voltage-gat
Blizzard [7]

Answer:

depolarization leading to action potentials

Explanation:

The voltage-gated Na+ channels are responsible for rapid depolarization phase of the action potential. Action potential generation require depolarization of neuronal membrane which is acquired by influx of sodium ions through voltage gated sodium ion channels. If the Na+ channels are blocked, there will be no influx of sodium ions to cause depolarization hence action potential will not be generated.

d1i1m1o1n [39]

Answer:

Needs optimum environmental conditions.

Explanation:

Seedling, a flower and a vegetable needs suitable conditions for growth and development. All of the three stages of plant life cycle requires optimum water, fertilizers and light intensity in order to grow and develop at full speed. Seeds need a specific temperature in order to germinate. Most seeds germinate when the soil temperature is between 68 and 86 Fahrenheit. In the same way the plant also needs specific temperature for bearing flowers. All the stages requires optimum water in the soil for absorption.
