Westkost [7]3 years ago
7 0

The correct answer is: 100x.

The calculation of total magnification of the microscope includes multiplying the magnification of the lenses together, So, to calculate the total magnification take the power of the objective (10X) and multiply by the power of the eyepiece, ocular lens (10X).

When a horizontally positioned plant responds to gravity,
barxatty [35]
When a horizontally positioned plant responds to gravity, then auxins in the lower sides of the stems cause cell elongation that bends the stem upright. The correct option among all the options that are given in the question is the first option. This action is mainly due to the nature of the plants to grow towards sunlight.

You are given two solutions containing different purified DNAs. One is from the bacterium P. aeruginosa and has a G + C composit
bonufazy [111]

Answer:

The solution of P. aeruginosa will yield higher Tm value.

Explanation:

The solution of P.aeruginosa contain 68% G+C composition as a result the DNA of P.aeruginosa is more stable than the DNA of mammal contain only 42% G+C composition.G+C composition is most stable because guanine is linked to cytosine by 3 hydrogen bonds whereas adenine linked to thymine by 2 hydrogen bonds.

   As  P.aeruginosa DNA is more stable than mammalian DNA,as a result the DNA solution of P.aeruginosa will yield high Tm(melting temperature) value than that of mammalian DNA.

Understand the process of base pairing in both DNA and RNA.
Ksenya-84 [330]

Answer:

The rules of base pairing explain the phenomenon that whatever the amount of adenine in the DNA of an organism, the amount of thymine is the same. Similarly, whatever the amount of guanine, the amount of cytosine is the same.

Hope it helps a lil! ^_^

Fill in the Blank: Transcription factors (proteins) help our cells to promote gene expression (e.g., the production of insulin)
leva [86]

Answer:

The correct answer will be option-C.

Explanation:

The RNA polymerase is the enzyme which synthesizes the mRNA molecules using a single strand of DNA.  RNA polymerase has the ability to bind nucleotide at 3' end of the strand thus proceeding the strand in 5' to 3' direction.

In the given question, gene expression of the insulin-producing gene has been discussed which uses transcription factors. The transcription factors assist RNA polymerase enzyme to attach to the promoter sequence and start synthesizing RNA molecule.

Thus, Option-C is the correct answer.
