A researcher is studying the synthesis of a specific amino acid found in Neurospora. She knows that the pathway begins with a pr

ecursor that is converted into the amino acid with two known intermediates (Substance Blue and Substance Green). She accurately predicts that this amino acid synthesis pathway is catalyzed by three enzymes, (I, II, and III). She subsequently identifies three mutants that she calls Mutant I, Mutant II, and Mutant III. With the information about the mutants below place the enzymes in the order that the enzymes act in this pathway. (Note: the numbers I, II, and III don't necessarily indicate the order in which the enzymes appear.)
- Mutant I (only Enzyme I is mutated) is unable to synthesize the amino acid even if she provided the mutant with both Substance Blue and Substance Green.
- Mutant II (only Enzyme Il is mutated) is able to synthesize the amino acid if she provided the mutant with Substance Blue or Substance Green.
- Mutant III (only Enzyme III is mutated) is able to make the amino acid if she provided the mutant with Substance Green, but not if she provided the mutant with only Substance Blue.
a. III, I, II
b. II, I, III
c. III, II, I
d. I, II, III
e. II, III, 1

What virus structure is similar in function to a cell membrane?
Korolek [52]

Answer:

viral envelope

The phospholipids in the viral envelope are similar to those in the plasma membrane of an infected host cell. The viral envelope is, in fact, derived by budding from that membrane, but contains mainly viral glycoproteins.

pentagon [3]
The women was a carrier of the color blind trait, its recessive so she passed the trait down on his only X chromosome, men are more likely to be color blind because they only have to have one faulty X chromosome. females have to have both X's wrong.
and O is also a recessive trait so they had AO and BO blood types and the OO matched up for there baby

Which statement is true about climate change and biodiversity?
8090 [49]
Climate change and biodiversity are two completely different things. In some areas, climate change will increase biodiversity, allowing more species to live in certain climates, but it will make some species lose their habitats. Biodiversity helps ecosystems thrive, and generally keeps things in balance. However, introducing too many species in an area can cause increase competition for food, risking predators of different species to kill one another off. Both climate change and biodiversity can be good and bad.

Answer: C. It can help some species and hurt others.

The brain volumes ​(cm cubed​) of 20 brains have a mean of 1116.2 cm cubed and a standard deviation of 127.7 cm cubed. Use the g
Shkiper50 [21]

Answer:

Yes

Explanation:

Range rule of thumb predicts the Range to be  a multiple of 4 of the standard deviation or to be four times  the standard deviation. Making the usual values equal to 2 standard deviations distanct of the mean of the data distribution.

In a given distribution with mean and standard deviation that is obtained, the usual values in mean (as seen in the attached image).

2*standard deviation and mean + 2*standard deviation.

If the data point is not up to the mean

- 2* standard deviation is taken to be significantly low.

If the data point is more than the mean

+ 2*standard deviation is taken to be significantly high.

Let's take the xbar to be the mean and s as standard deviaiton

Given,

mean, xbar = 1116.2

standard deviation, s =127.7

The range rule of thumb shows that the usual values are within 2 standard deviations from the mean

Lower boundary

      = xbar - 2s

       = 1116.2 - 2(127.7)

       = 860.8

Upper boundary

      = xbar + 2s

       = 1116.2 + 2(127.7)

       = 1371.6

We should note that 1411.6 is not between 860.8 and 1371.6, which connotes that 1411.6cm^3 is unusually high.
