A botanist has acquired a group of sweet pea plants. All of the plants have yellow pea pods (the recessive trait), except for on
Advocard [28]

Answer:

In order to find out the genotype we do a testcross of green pea pods with yellow pea pods.

Explanation:

1. If the F1 generation consist of green pea pods only then the genotype of the green pea pod is 'GG' (i.e the dominant alleles).  

<h2>                           TEST CROSS </h2>

                    Green pea pods        X           Yellow pea pods

                                    GG              X              gg

       <u>Gametes: </u>

                                     G               X                g

      <u> F1 Generation: </u>

<h2>                                 Gg </h2>

2. However if the F1 generation consist of 50% green pea pods and 50% yellow pea pods then the genotype of green pea pods is 'Gg' (both the dominant and recessive alleles).

                   Green pea pods        X           Yellow pea pods

                               Gg                  X               gg

       <u>Gametes: </u>

                           G      g      X        g

       <u>F1 Generation:</u>

<h2>                              Gg, gg </h2>

We can relate this to Mendel's Law of segregation and meiosis as

  • Both the alleles segregate into seperate gametes (i.e they are sorted independent of one another).
  • This segregation is similar to the first division of meiosis in which homologous chromosomes of gene are segregated in daughter nuclei

<h2>Gram Negative and Positive Bacteria</h2>

Explanation:

  • The cell wall of <em>gram-positive bacteria is a peptidoglycan macromolecule </em>with joined adornment molecules, for example,<em> teichoic acids, teichuronic acids, polyphosphates, or sugars</em>
  • <em>Gram-negative bacteria</em> organisms are not destroyed by specific cleansers which easily <em>kill Gram-positive bacteria </em>
  • Surface displayed proteins on microbes play key role in <em>pathogenesis </em>as they elevate bacterial attachment to have tissues, acquisition of essential nutrients, evasion and suppression of<em> immune response and host cell entry</em>

Duration of hypotension before initiation of effective antimicrobial therapy is the critical determinant of survival in human se
nydimaria [60]

The goal is to find out how often effective antimicrobial therapy is delayed after the start of persistent or recurrent hypotension in septic shock and how this affects mortality.

Design: A cohort research that was conducted in retrospect between July 1989 and June 2004.

Setting: Ten hospitals (four academic, six community) and fourteen critical care units (four medical, four surgical, and six combined medical/surgical) located in Canada and the United States.

Patients: The 2,731 adult patients with septic shock listed in their medical records.

Measurements and key findings: Survival to hospital discharge served as the primary outcome indicator. A survival percentage of 79.9% was found when an antibiotic efficacious for isolated or suspected infections was administered within the first hour of verified hypotension. Over the following 6 hours, each hour of antibiotic delivery delay was linked to an average 7.6% decline in survival. When compared to obtaining treatment within the first hour after the beginning of persistent or recurrent hypotension, the in-hospital mortality rate was considerably higher by the second hour (odds ratio 1.67; 95% confidence range, 1.12-2.48). The single best predictor of outcome in multivariate analysis (which included Acute Physiology and Chronic Health Evaluation II score and treatment factors) was time to the start of effective antimicrobial therapy. It took 6 hours on average to start effective antimicrobial therapy (25-75th percentile, 2.0-15.0 hrs).

Conclusions: In adult patients with septic shock, effective antibiotic therapy during the first hour of confirmed hypotension was related with enhanced survival to hospital discharge. Only 50% of patients with septic shock got efficient antimicrobial therapy within 6 hours of being diagnosed with proven hypotension, despite a steady rise in fatality rate with increasing delays.

<h3>What is septic shock?</h3>

Septic shock is a potentially fatal illness that develops after an infection when your blood pressure drops to an unsafely low level. The infection might be brought on by any kind of bacterium.
