Which column represents the independent variable and which axis should it be plotted on quizlet?
Which column represents the independent variable, and which axis should it be plotted on? Time (in days) is the independent variable. It is not changed by the other variables measured. The independent variable is plotted on the x-axis.
Which of the following statements best describes the role of mast cells in the inflammatory response?
Which of the following statements best describes the role of mast cells in the inflammatory response? They release chemicals that dilate blood vessels near the wound site, allowing blood components to enter the region from the bloodstream.
Which of these cells is responsible for the rapidity of the secondary immune response?
plasma cells and memory cells… The antigen-selected proliferation of B cells produces clones of plasma cells and memory cells. Which of these cells is responsible for the rapidity of the secondary immune response? memory cells….
How does an antihistamine reduce allergy symptoms quizlet?
How does an antihistamine reduce allergy symptoms? An antihistamine blocks receptors for inflammatory chemicals released from granules within mast cells. An antihistamine kills mast cells, blocking an allergic reaction. An antihistamine binds pollen antigens, preventing them from provoking an allergic reaction.
When graphing data from an experiment levels of an independent variable are normally represented along the?
The Axes. The independent variable belongs on the x-axis (horizontal line) of the graph and the dependent variable belongs on the y-axis (vertical line). The x and y axes cross at a point referred to as the origin, where the coordinates are (0,0).
Which would you use to compare data that you collected by counting?
Bar graphs are best used to compare information collected by counting.
Which of the following is the correct sequence of events that occurs during an inflammatory response?
So, the correct answer is, 'Vasodilation → Adhesion → Emigration → Chemotaxis → Diapedesis → Phagocytosis. ' Note: The series of events within the process of inflammation are: -Vasodilation: results in greater blood flow to the area of inflammation, leading to redness and warmth.
Which of the following are the three phases of inflammation?
The Three Stages of Inflammation
- Written by Christina Eng – Physiotherapist, Clinical Pilates Instructor.
- Phase 1: Inflammatory Response. Healing of acute injuries begins with the acute vascular inflammatory response. …
- Phase 2: Repair and Regeneration. …
- Phase 3: Remodelling and Maturation.
What are the differences between the primary and secondary immune responses?
The main difference between primary and secondary immune response is that primary immune response occurs in response to the primary contact with the antigen whereas secondary immune response occurs in response to the second and subsequent exposure to the same antigen.
What is the difference between the primary and secondary immune response quizlet?
What is the difference between a primary and secondary immune response? primary: body is first exposed to antigen, lymphocyte is activated. secondary: same antigen is encountered at a later time. It is faster and of greater magnitude.
How does the immune system of vertebrates utilize a chemical concentration gradient?
–The immune system releases chemical signals called chemokines, which create a chemical gradient that leukocytes use in migrating toward the infection site. The immune system releases chemical signals called chemokines, which create a chemical gradient that leukocytes use in migrating toward the infection site.
What is the difference between T lymphocytes and B lymphocytes quizlet?
Explain the difference between B lymphocytes and T lymphocytes. Type B lymphocytes form in the bone marrow and release antibodies that fight bacterial infections. Type T lymphocytes form in the thymus and other lymphatic tissue and attack cancer cells, viruses, and foreign substances.
What type of analysis would you use for an experiment with 2 independent variables with 3 levels each?
A 2×3 factorial design is a type of experimental design that allows researchers to understand the effects of two independent variables on a single dependent variable. In this type of design, one independent variable has two levels and the other independent variable has three levels.
When graphing the relationship between an independent variable and a dependent variable the independent variable should be on the ______?
The independent variable belongs on the x-axis (horizontal line) of the graph and the dependent variable belongs on the y-axis (vertical line). The x and y axes cross at a point referred to as the origin, where the coordinates are (0,0).
How do you compare data sets?
It may be useful to compare two sets of data using the mean, mode or median in order to draw conclusions about the information presented. You may be choosing one measure over another for its accuracy or choosing the one that best backs up what you want to show.
How do you compare two sets of data in statistics?
When you compare two or more data sets, focus on four features:
- Center. Graphically, the center of a distribution is the point where about half of the observations are on either side.
- Spread. The spread of a distribution refers to the variability of the data. …
- Shape. …
- Unusual features.
What is the correct sequence of events during inflammation in response to bacterial invasion?
So, the correct answer is, 'Vasodilation → Adhesion → Emigration → Chemotaxis → Diapedesis → Phagocytosis. ' Note: The series of events within the process of inflammation are: -Vasodilation: results in greater blood flow to the area of inflammation, leading to redness and warmth.

What are the 3 normal local inflammatory responses to an infection?
Inflammatory reactions
- Local hemodynamic changes (vascular response to injury) Initial vasoconstriction is followed by vasodilation → stasis and ↑ blood flow. …
- Increased vascular permeability. …
- Cellular effects.

What are some of the differences between primary and secondary antibody responses to a protein antigen?
Primary antibodies bind to the antigen detected, whereas secondary antibodies bind to primary antibodies, usually their Fc domain. Secondly, primary antibodies are always needed in immunoassays, whereas secondary antibodies are not necessarily needed, which depends on experimental method (direct or indirect labeling).
What is the difference between the primary and secondary immune response?
The action of the immune system can be classified into two parts: the primary and the secondary immune response. The primary immune response displays the first contact of the immune system with an infectious agent whereas all following contacts with the same pathogen are named secondary immune response.
What is the difference between humoral and cellular adaptive immunity quizlet?
Terms in this set (12) In humoral immunity responses, B Cells produce antibodies after being activated by free antigens present in body fluids. In cell-mediated immunity responses, T cells attack infected body cells that display the antigens of pathogens on their surface.
What are the 3 main functions of the complement system?
At the basic level the broad functions of the complement system can be split into three areas: (1) the activation of inflammation; (2) the opsonization (labeling) of pathogens and cells for clearance/destruction; (3) the direct killing of target cells/microbes by lysis.
What is complement system explain about the structure components and its properties?
The complement system is made up of a large number of distinct plasma proteins that react with one another to opsonize pathogens and induce a series of inflammatory responses that help to fight infection. A number of complement proteins are proteases that are themselves activated by proteolytic cleavage.
What is the difference between T lymphocytes and B lymphocytes?
T cells can wipe out infected or cancerous cells. They also direct the immune response by helping B lymphocytes to eliminate invading pathogens. B cells create antibodies. B lymphocytes, also called B cells, create a type of protein called an antibody.
How are the roles of B and T cells similar and different?
T cells are responsible for cell-mediated immunity. B cells, which mature in the bone marrow, are responsible for antibody-mediated immunity. The cell-mediated response begins when a pathogen is engulfed by an antigen-presenting cell, in this case, a macrophage.
What is the difference between a factorial ANOVA and a mixed ANOVA?
However, the fundamental difference is that a two-way repeated measures ANOVA has two "within-subjects" factors, whereas a mixed ANOVA has only one "within-subjects" factor because the other factor is a "between-subjects" factor.
What type of ANOVA allows for multiple independent variables and one dependent variable?
A two-way ANOVA is an extension of the one-way ANOVA (analysis of variances) that reveals the results of two independent variables on a dependent variable.
Which type of chart plots the relationship between dependent and independent variables?
A scatter plot is often used to show relationships between independent and dependent variables. Instead of connected data points with a line, a best-fit line can be used to find a trend in data. Scatter plots are frequently used for creating a standard curve in chemistry, as is shown in the graph below.
