The Go' for the reaction Citrate  Isocitrate is +6.64 kJmol-1 . The Go' for the reaction Isocitrate  α-Ketoglutarate is -267 kJmol-1 . Calculate the Go' for the conversion of citrate to α-ketoglutarate?

Answers

Answer:

ΔG°' for the conversion of citrate to α-ketoglutarate = - 273.64  kJmol-1

Explanation:

ΔG°' for Citrate is +6.64 kJmol-1

ΔG°' for Isocitrate is -267 kJmol-1

ΔG°' for the conversion of citrate to α-ketoglutarate = ΔG°' for product - ΔG°' for reactant

ΔG°' for the conversion of citrate to α-ketoglutarate = -267 kJmol-1 - (+6.64 kJmol-1)

ΔG°' for the conversion of citrate to α-ketoglutarate = - 273.64  kJmol-1

Approximately 20% of the world’s adult population are able to digest milk sugar (lactose).They are “lactose tolerant.” This trait is known to be controlled by a single dominant gene. Therefore, we would expect that

no lactose tolerant individuals have two biological parents that are lactose INtolerant.

all lactose tolerant individuals to be heterozygous for the gene.

60% of lactose INtolerant individuals would be heterozygous.

all children of lactose tolerant parents will also be lactose tolerant.

Answers

Answer:

No lactose individuals have two biological parents that are lactose intolerant

Explanation:

In this case lactose intolerance would be coded for a recessive gene (r). if both parents are lactose intolerant the would both be the genotype (rr) . For individual to be lactose intolerant atleast one parent most be lactose tolerant posesing the dominant (R) gene. Which both parents in this example lack.

Which description explains why there are two high and two low tides in a day? (4 points)

Earth moves closer to the sun and moon twice a day.

Earth revolves around the tidal bulges created by gravitational forces.

Earth rotates in and out of a tidal bulge twice a day.

The moon's gravity increases over the oceans and decreases over the land.

Answers

Answer:

Earth rotates in and out of a tidal bulge twice a day.

Earth always has two surrounding gravitational forces, one proceeding from the moon and one from the sun.

The sun's pull, despite the fact our sun is further then the moon, is stronger and creates the high tide, and the moon the low tide. But as we know our earth moves, now exposing the other side to the sun which in turn leaves the other side of earth with the high tides and the other with the low tides. Tides never move, what moves is earth.

Resolved, That as slavery does not exist by law, and is not likely to be introduced into any of the territory acquired by the United States from the republic of Mexico, it is in- expedient for Congress to provide by law either for its introduction into, or exclusion from, any part of the said territory; and that appropriate territorial governments ought to be established by Congress in all of the said territory , not assigned as the boundaries of the proposed State of California, without the adoption of any restriction or condition on the subject of slavery.5.

Does meditation cure insomnia? Researchers randomly divided 400 people into two equal-sized groups. One group meditated daily for 30 minutes, the other group attended a 2-hour information session on insomnia.At the beginning of the study, the average difference between the number of minutes slept between the two groups was about 0. After the study, the average difference was about 32 minutes, and the meditation group had a higher average number of minutes slept.To test whether an average difference of 32 minutes could be attributed to chance, a statistics student decided to conduct a randomization test. She wrote the number of minutes slept by each subject in the study on an index card. She shuffled the cards together very well, and then dealt them into two equal-sized groups, representing those who meditated and those who attended the information session.Which of the following best describes the outcome of the randomization test.O The average difference between the two values on the two stacks of cards is expected to be about 0 minutes.O If meditation is effective, the average difference between the values on the two stacks of cards is expected to be more than 32 minutes.O The average difference between the two values on the two stacks of cards is expected to be about 32 minutes.
