A spinal-epidural, also called a(n) __________ epidural, is a system of administering continuous doses of anesthetic to a woman
Rudik [331]

The epidural anesthesia is a method of pain relief, which is used during the labor pain. It is a well known regional anesthesia. It works by acting as an analgesic, which means a substance that eases the pain, a complete anesthesia or loss of feeling does not occur in the case of epidural anesthesia. It blocks the nerve signals from the lower spinal segments. It is also known as spinal epidural anesthesia or lumbar epidural anesthesia.  

Hence, the black can be filled with lumbar.

This problem has been solved!
larisa [96]

Answer:

The smallest size tube that will hold the entire reaction is 0.5ml

Explanation:

25ul (DNA sample) + 25ul (enzyme) + 50ul (buffer) + 400ul (water) = 500ul total

since 1000ul=1ml, then 500ul = 0.5ml

Answer:

The device that mostlikely would not be used P20

Explanation:

P20 is a pipette used to measure and sample volumes of 20ul maximum.

Answer:

The reaction mix will have 400 units of the enzyme.

The working dilution will be 0.8 Units/ul.

Explanation:

The mix has 20ul of the enzyme which is 20Units/ul. Then we have 20ulx20Units/ul= 400 Units of enzyme in the mix.

Since the final volume is 500ul, the final concentration 400Units/500ul=0.8 Units/ul.

A man and a woman are both carriers for two autosomal recessive disorders, PKU (chromosome 12) and cystic fibrosis (chromosome 7
ValentinkaMS [17]

Answer:

Pr= (3/16)

Explanation:

It was stated that both the man and the woman are both carriers for two autosomal recessive disorders, PKU (chromosome 12) and cystic fibrosis (chromosome 7).

∴ let Aa¹Bb° represent the traits in the Man

Where;

Aa¹ = carrier of PKU

Bb° = carrier of cystic fibrosis

Also, let Cc¹Dd° represent the traits in the woman

Where;

Cc¹ = carrier of PKU

Dd° = carrier of cystic fibrosis

Now, if Aa¹Bb° self-crossed, we'll have the F1 progeny as AB, Ab° , a¹B and a¹b°

also, if Cc¹Dd° self-crossed, we have CD, Cd° , c¹D and c¹d° as their F1 progeny

In the F2 generation, the dihybrid cross between the F1 generations will be:

AB, Ab° , a¹B, a¹b°    × CD, Cd° , c¹D, c¹d°

ACBD, ACb°D, a¹CBD, a¹Cb°D

ACBd°, ACb°d°, a¹CBd°, a¹Cb°d°

Ac¹BD, Ac¹b°D, a¹c¹BD, a¹c¹b°D

Ac¹Bd°, Ac¹b°d°, a¹c¹Bd°, a¹c¹b°d°

Only (a¹CBD, Ac¹BD, a¹c¹BD)  shows the probability that she will have PKU but not CF.
