Answer:

IgA, IgM, IgD, IgE.

Explanation:

Antibodies are known as proteins that are produced and secreted by B-cells. They help to bind foreign substances that invade the body, for example, pathogens. The "antibody" term refers to its function, which is to bind with an antigen. This protein molecule is also known as immunoglobulin.

Body fluids attack and destroy specific antigen-bearing particles or antigens through antibody-mediated immunity. There are 5 types of antibodies are present:

1) IgA

2) IgM

3) IgD

4) IgE

5) IgG.

Migration of a random few individuals from one population to a new area to establish a new population is an example of:_________
NARA [144]

Founder effect is the example of migration of a random few individuals from one population to a new area to establish a new population.Thus, option C is correct.

What is migration?

Migration is defined as movement of individuals from one place to another in search of employment and livelihood.Some people lives permanently after migration and some returns back to the native place.

Internal migration is the type of migration in which people migrate within state and country.

External migration is the migration to different state and country.

The phenomenon of moving into new place is known as immigration.

Seasonal migration is the migration in which animals or humans migrate in a particular season due to climatic condition.

Therefore,migration of a random few individuals from one population to a new area to establish a new population is an example of founder effect.

Will more air inside a basketball make it bounce higher?
marysya [2.9K]

The outcome variable, test variable, and controlled variable for each question is as follows:

  • outcome variable = bounce height; test variable = volume of air, and  controlled variable = basketball
  • outcome variable = cleaning property; =  test variable = type of cleaner, and  controlled variable = cloth
  • outcome variable = heat absorbed; test variable = fabric color, and  controlled variable = amount of sunshine
  • outcome variable =  plant size, test variable = seed size, and  controlled variable = sunlight
  • outcome variable = flower freshness, test variable = sugar added to water, and controlled variable = sunlight
  • outcome variable = adhesion of tape; test variable = differences surfaces, and controlled variable = paper
  • outcome variable =  volcano eruption, test variable =  ratio of vinegar to baking soda, and controlled variable = container or bottle

<h3>What are variables in an experiment?</h3>

A variable is any factor in an experiment that can be manipulated, controlled for, or measured.

There are three types of variables in an experiment:

  • Dependent variable or outcome variable
  • Independent variable or test variable,
  • Constant variable or controlled variable

The Dependent variable or outcome variable depends on changes in the independent variable.

An independent or test variable is the variable that stands alone and is not affected  by other factors in the experiment.

The constant or controlled variable is unchanged.

The outcome variable, test variable, and controlled variable for each question is as follows:

1. Will more air inside a basketball make it bounce higher?

  • outcome variable = bounce height;  test variable = volume of air, and  controlled variable = basketball

2. Do ''green'' cleaners clean as well as store bought cleaners?

  • outcome variable cleaning property; =  test variable = type of cleaner, and  controlled variable = cloth

3. Which colors of fabric absorbs most heat?

  • outcome variable = heat absorbed; test variable = fabric color, and  controlled variable = amount of sunshine

4. Do bigger seeds make bigger plants?

  • outcome variable =  plant size, test variable = seed size, and  controlled variable = sunlight

5. Does sugar added to water improve cut flower freshness?

  • outcome variable = flower freshness, test variable = sugar added to water, and controlled variable = sunlight

6. How do differences in surfaces affect the adhesion of tape?

  • outcome variable = adhesion of tape; test variable = differences surfaces, and controlled variable = paper

7. What ratio of vinegar to baking soda produces the best chemical volcano eruption?

  • outcome variable =  volcano eruption, test variable =  ratio of vinegar to baking soda, and controlled variable = container or bottle

In conclusion, changes done to the test variable results in changes in the outcome variable.
