Agent that kills microorganisms, rather than inhibits it: bactericid e

Microbial growth can be controlled and that control usually involves the use of physical or chemical agents. Chemical agents which either kill the microorganisms are called cidal agents while those that prevent their growth are referred to as static agents. of microorganisms. Thus, the term bactericidal refers to killing bacteria, and bacteriostatic refers to inhibiting the growth of bacterial cells.

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.

Can share electrons in single pairs, double pairs, or triple pairs. share electrons in triple pairs. share electrons in single p

Rama09 [41]

The way I'm interpreting this is that what type of bound are these? And yes share electrons in various bonds can share electrons lose and gain, these all sounds like covalent bonds and ionic and hydrogen bounds are from.single to double and to triple bounds.

Como se mantienen unidos los puentes de hidrogeno

Alex787 [66]

Answer:

Los puentes de Hidrógeno, se forman por átomos de Hidrógeno localizados entre átomos pequeños muy electronegativos, cuando un átomo de Hidrógeno está unido covalentemente, a un átomo electronegativo, Oxígeno, Nitrógeno o Flúor, el átomo con mayor electronegatividad atraerá hacia si los electrones del enlace, formándose
