Answer:

<em>The number of fish would decrease.</em>

Explanation:

Ecological hypoxia can be described as a condition in which the oxygen level drops to such low levels in the aquatic ecosystem that it is no longer able to support aquatic life. In such a condition, the number of fishes declines at a rapid rate because fishes require oxygen as an essential element. Also, those fishes which do not have better adaptations to survive might get totally wiped out from the aquatic ecosystem.

How do egg whites remain liquid during the pasteurization of liquid egg products? egg whites are separated out before pasteuriza
Fittoniya [83]

Egg whites are separated out before pasteurization.

First, the eggs are washed and candled. They are then broken and yolks and egg whites are separated. The liquid eggs run through a filter to make sure there are no more egg shells. The liquid egg whites the pass through pipes heated at temperatures that can kill the microorganisms without cooking it. It is then cooled and packaged for use

Question 7 (3 points)<br> Which of the following describes the law of original horizontality?
Naddik [55]

Answer:

"Folded sedimentary layers were originally laid down flat and later deformed." describes the law of original horizontality.

Explanation:

In terms of structural geology, the folds happens when the one over the another are piled up on a flat as well as planar structure i.e. sedimentary strata. Which sometimes are bent or may be curved because of the permanent deformation. Both upward as well as downward folds occurs in the sedimentary fold. Which is known as the anticline or the syncline. There are three major folds in case of the sedimentary layers they are monocline, anticline and syncline. Simple bend layers are called as the monoclines.

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.
