A man with normal vision and a colorblind woman have children together. We can expect that _________ of their sons and _________
MrMuchimi
The answer would be E because boys inherit the Y chromosome from the dad which in this case would have the color blind trait. Girls don’t get the y from the father to get the color blind trait not be color blind because girls have 2 (X) chromosomes. Hope this helps

Which of the following routinely occurs in both eukaryotic and prokaryotic transcription?a. the RNA polymerase undergoes abortiv
Salsk061 [2.6K]

Answer:

a. the RNA polymerase undergoes abortive initiation prior to promoter clearance

Explanation:

In eukaryotes the 3' end of the mRNA is polyadenylated to protect the mRNA from degradation.

In eukaryotes, a modified guanine cap is added to the 5' end of the mRNAd to protects the transcript from being broken down.

Most bacterial RNA transcripts do not undergo splicing.

The nucleosome is the basic unit of chromatin repeat in eukaryotes.

How much 3M NaOH (MW=40) can be made from 10.0mL of a 10M solution?
vaieri [72.5K]

Explanation:

The given data is as follows.

              M_{1} = 3 M,           V_{1} = ?

              M_{2} = 10 M,         V_{2} = 10.0 ml

Therefore, calculate the volume of given solution as follows.

              M_{1} \times V_{1} = M_{2} \times V_{2}

Now, putting the given values into the above formula as follows.

            M_{1} \times V_{1} = M_{2} \times V_{2}

            3 M \times V_{1} = 10 M \times 10.0 ml    

                   V_{1} = 33.3 ml

or,                             = 0.033 L        (as 1 ml = 0.001 L)

Since, molarity of NaOH is given as 3 M and its volume is calculated as 33.3 ml.

           Molarity = \frac{\text{mass of solute}}{\text{molar mass of solute}} \times \frac{1}{\text{volume in L}}

               3 M = \frac{mass}{40 g/mol \times 0.033 L}

              mass = 3.96 g

Therefore, we can conclude that mass of NaOH is 3.96 g.
