Which of the following statements is true of offspring from organisms that reproduce asexually?
Veronika [31]
A) the offspring are genetically identical to the parent. 
The reason for this is that there are no different traits being passed down that could alter the offspring's appearance. If there is sexual reproduction, then the offspring shares both of the parent's traits. If there is only one parent, then there is less diversity. <span />

The human stomach secretes an enzyme known as pepsin. This enzyme breaks down proteins into smaller chemical molecules called pe
emmasim [6.3K]
The question here is, is glucose a protein? No, it's not; it's a carbohydrate.

So pepsin would not break it down: it would most probably not react with glucose at all, since pepsin breaks down proteins, not carbohydrates. <span />

Many drugs can be applied to the skin without entering the blood. how is this fact explained?
ra1l [238]

*A drug administered by the cutaneous route can have one of these three actions:

Local action, superficial: ex. local anesthetic ...

Deep action: ex. anti-inflammatory action ...

Systemic or general action: ex. anti-anginal action

*The skin is a very effective barrier, which limits the number of drugs that can enter the system.

*The factor influencing the penetration of the drugs are:

- Nature and physicochemical properties of P.A: Molecular weight, hydrophilicity, lipophilicity, stability ...

- Formulation of the drug: Excipients lipophilic, hydrophilic, amphiphilic, an absorption promoter

- Nature and condition of the skin, Location, age, thickness (1 to 8 mm ...), vascularization...

*To not penetrate the skin, a drug should have to be of high molecular mass (to be unable to penetrate through the skin tissue), hydrophilic (since the skin is of a lipophilic nature).

*For example, solar creams should not enter the system so the excipients used are hydrophilic in nature.

anygoal [31]

Answer:

Lithospheric

Explanation:

Lithospheric plates are part of a planetary scale thermal convection system. The energy source for plate tectonics is Earth's internal heat while the forces moving the plates are the “ridge push” and “slab pull” gravity forces

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.
