1) Sperm cell is adapted to its function by carrying genetic information to an egg.

2) It has a stream lined body that allows it to move quickly.

3) They also contain large number of mitochondria in the mid region, so it is able to produce a lot of energy in order to operate tail

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.

Give reasons :
lesantik [10]

Answer:

a) It is dangerous to wear nylon clothes while cooking because it is a synthetic cloth and they catch fire easily also they can stick on our body which is very painful.

b) Cotton is a natural product. And unlike synthetic fibres, it is more absorbent. The towel hence has high absorbency.

c) Nylon and polyester are two fabrics most commonly used in raincoats and umbrellas. They are not absorbent the way natural fibers are. They naturally resist waterlogging, and can be made waterproof.

In which of the following situations is evolution by natural selection most likely to occur?
Varvara68 [4.7K]

Answer:

b.

Explanation:

Natural Selection refers to the survivability of organisms based on different traits or genes that they have which then get passed on to their offspring. Based on this information we can say that a population of mountain gorillas in which individuals with genes for long hair survive the cold better is the situation in which natural selection is most likely to occur. This is because longer hair in this scenario is a gene that drastically affects the chance of survival for the gorillas and will most likely be passed on to their offspring.

Differential survival and reproduction is best described by which term? natural selection creationism inheritance of acquired ch
Sophie [7]
I believe it is natural selection. Natural selection is when over a period of time, traits that are formed to help the organism survive, are passed to the next generation. For example, if there were two types of rabbits. One had black fur and the other was white. They both lived in the artic. The black furred rabbits are mostly eaten by predators because their black fur is easily seen against the ice and snow. Over a period of time, the black furred rabbit would die out. The next generation would mostly have white fur to help them survive.
