No, it is not a reasonable gamble for Karen to skip the influenza vaccine this year.
There are many factors which can increase a person's risk of developing the influenza virus and some of these factors are age, health condition, weakened immune system, pregnancy, or chronic illnesses.
Karen is older and her age could act as a risk factor for influenza. In addition, each year there are different strains of the virus since the virus is constantly changing and evolving. Given this, a person who got the vaccine last year is still in danger of not having the antibodies which can protect from this year's strain.
Karen should get the influenza vaccine this year as well.
Answer:
Independent variable: varying amounts of light
Dependent variable: plant growth
Explanation:
The variable, which are factors that can be altered, in an experiment can either be independent or dependent. An independent variable is one in which the experimenter manipulates or controls in order to bring about an outcome. For this experiment conducted by Rachel, the independent variable is the VARYING AMOUNT OF LIGHTS.
The dependent variable is the variable that responds to changes of the independent variable. In other words, the dependent variable is the outcome of manipulating the independent variable. Hence, the dependent variable is dependent on the independent variable. For Rachel's experiment, the PLANT GROWTH is the dependent variable because it is what responds to changes in amount of light (independent variable).
A piece of foam with an open cell structure is introduced into the wound and a wound drain is placed with lateral perforations on top. The entire area is covered with a transparent adhesive membrane, which is firmly fixed to healthy skin around the wound margin. When the exposed end of the drain tube is connected to a vacuum source, fluid is withdrawn from the wound through the foam into a reservoir for later disposal.It is necessary to cover the wound bed with a soft polyvinyl alcohol foam sponge, a non-stick oil-emulsion dressing (for exame, Johnson and Johnson), a contact layer (such as Mepitel), a thin layer of amorphous hydrogel (can be Intrasite Gel), or a calcium alginate (such as Sorbsan) before application of the gray sponge. Avoid the use of Vaseline, which is too oily and can alter the adhesion of the VAC cloth.
