You are given an experimental problem involving control of a gene's expression in the embryo of a particular species. One of you
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.

Make a decision about the molecule NaHCO3 classification organic or inorganic
motikmotik

<u>Answer:</u>

NaHCO_{3} is an inorganic compound.

<u>Solution:</u>

  1. Firstly, all the known definitions of organic compounds excludes Carbonic acid and it's salt from organic compounds except if 'C' is present in the cation.  
  2. Secondly, Sodium is a metal which organic compounds cannot posses as a compound.  
  3. Lastly, there is absence of C-H bond which is present in all the organic compounds.

Hence, we can conclude that NaHCO_{3}is an inorganic compound though there is presence of Carbon atom in it.

Which of the following results from cutting down trees
ZanzabumX [31]

Answer:

D

Explanation:

Vegetation on soil protects the soil from erosion because its roots and root hairs help bind the soil particles together. This occurs mechanically by binding soil into crumbs and also chemically by providing organic matter that binds the soil particle into humus that holds moisture. The soil becomes heavy to be carried off by wind erosion. Trees also break the down flow of water hence reducing the capacity of runoff to carry soil sediments.
