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.

As a character of all living things, homeostasis relates most directly to which of the following biological themes
Novosadov [1.4K]

Explanation:

As a characteristic of all living things, homeostasis relates most directly to which of the following biological themes?

A.) Interacting systems.

B.) Stability.

C.) Evolution.

D.) Scale and structure.

Correct: B.) Stability.

During homeostasis the body maintains a constant internal balance (stability) in pH, temperature, blood pressure etc. Cells in a multicellular organism become specialized for particular tasks and communicate with one another in order to maintain homeostasis.

Within the human body these are known as hormone cascades, where several complex steps occur- the tissues signal to one another with the use of hormones released by the endocrine system. The regulation (increase and decrease) of these secretions is achieved by negative feedback loops, where the release of certain substances during a cascade in turn halts the secretion of hormones at earlier stages.

Which food is at a temperature that allows bacteria to grow well ? A) a roast at 125•F (52•c) B) hamburgers at 165•f (74•c) C) p
Lilit [14]

The correct answer is A) A roast at 125°F (52°C)

Explanation:

In general terms, bacteria thrive at warm temperatures; this means bacterial growth is lower at extremely hot/cold temperatures, but it is higher at warm or medium temperatures. Indeed, the ideal temperature for bacteria to develop and reproduce is between 4° C and 60°C. This implies from the options given the roast at 52°C represents an ideal temperature for the growth of bacteria. Also, other options include temperatures above 60°C, and therefore do not allow bacteria to grow well.
