Answer:

. 2C- acetyl Co-A from the link reaction  enters the kreb Cycle to combine with 4 Carbon Oxaloacetate to form 6-  Citrate

The Citrate forms intermediate Isocitrate, which eventually formed  6-C alpha ketoglutarate.

The alpha-ketoglutarate forms the intermediate succinyl-Co A, which later formed  5C-succinate.

5C -Succinate  forms 4C-fumarate, the latter formed 4C-malate- which eventually formed 4C-oxaloacetate.

The 4C of these compounds is fixed, to ensure constant availability of 4C of oxaloacatate for 2C Acetyl -CoA to bind it for the cycle to continuously occur for production of first product Citric Acid  from which other products are  formed from.

Answer:

Pneumonia may be defined as the medical condition in which the inflammation might occur in the lungs due to which the fluid might accumulate in the lungs. The infection might occur by the Streptococcus penumoniae bacteria.

The most likely diagnosis of this patient can be influenza. The symptoms shown by the patient like cough, fever, headache, lung pain is more common in influenza. The diagnosis can be based on the symptoms shown by the patient and no presence of the Streptococcal infection. This conditions can be worsened if the pneumonia follow the harsh influenza and this secondary infection must be monitored.  The treatment that can be preferred in this patient bed rest, anti pyretic medicines and proper body fluids.

Which of the proposed models for the mechanism of initial transcription suggests that the entire RNA polymerase enzyme moves alo
Degger [83]

Answer:

The right answer is Letter A

Explanation:

The proposed model for the mechanism of initial transcription that suggests the entire RNA polymerase enzyme moves along the DNA is <em>transient-excursion model</em>, and the proposed model that is best supported by experimental findings is<em> scrunching model.</em>

<em>Because RNA polymerase leaves the promoter, translocate a short way along DNA template, synthesizes a short transcript before aborting transcript, releasing the transcript and returning to its original location on promoter. That is the transient-excursion model.</em>

<em>The scrunching model downstream DNA is pulled into the enzyme and has accumulated within the enzyme as single stranded bulges.</em>

<em>Experiments show that scrunching is right, experiments using single molecule analyses that allow the positions of different parts of polymerase to be measured relative to each other and to the template DNA during transcription.</em>

dem82 [27]

Answer:

c. Physical adaptations to the environment drive the distribution of all three species in the wild.

Explanation:

Options A and B refer to competition between species. The experiment was about the colonizing ability of the three species, and not the interaction among them. So these two options are not correct.

Option D states that species A is better adapted to the upper intertidal zone than the middle or lower. But the table shows that species A is equally adapted to colonize upper and middle intertidal zone, and less adapted to colonize lower zones.

The correct option is C. When these competing species coexist, this is because of niche partitioning or niche differentiation. If there is not any differentiation between them, the dominant species displaces the weak species. In the exposed example,  the three species coexist in the middle and lower zones, which means that they probably have different niches and got adapted to living to their environments. This adaptation to different conditions is what leads to their distribution.    

In the exposed example, species A and B can live in the upper intertidal zone, where species C can not live because they can not tolerate environmental conditions. The three species can live in the middle zone, but still, A and B are more adapted to this area than C. Among A and B, B is the most adapted to living in the upper and middle zones. Species C seems to be very adapted to live in the lower intertidal zone, where species A and B can also live, but are less adapted to this area, probably due to environmental conditions or due to their vulnerability to predation. In this last area, species A is less adapted.

Which of the following is one of the five causes of a business cycle?
Rama09 [41]

C recession is one of the five causes of a business cycle. 
Business cycles are measured by looking at the growth rate of the gross domestic product of a country. There are five causes of a business cycle:
1. Changes in interest rates2. Changes in house prices3. Changes in consumer and business confidence 4. The local or world economy moves into a recession5. The local or world economy moves out of a recession. 
These causes can also be seen as unstable fluctuations rather than stable cycles.
