What kind of variable is behavior? An ordinal variable is a categorical variable for which the possible categories can be placed in a specific order or in some ‘natural’ way. In Table 2, the variable ‘behaviour’ is ordinal because the category ‘Excellent’ is better than the category ‘Very good’, etc. Which of the following is […]

What is the ability to change matter? Energy is defined in science as the ability to move matter or change matter in some other way. Energy can also be defined as the ability to do work, which means using force to move an object over a distance. How does energy cause changes? HOW DOES ENERGY […]

Which is called the living part of a cell? Protoplasm (/prəʊtə(ʊ)ˌplaz(ə)m/, plural protoplasms) is the living part of a cell that is surrounded by a plasma membrane. In some definitions, it is a general term for the cytoplasm (e.g., Mohl, 1846), but for others, it also includes the nucleoplasm (e.g., Strasburger, 1882). Is a living […]

What is Mew M? The micrometre (international spelling as used by the International Bureau of Weights and Measures; SI symbol: μm) or micrometer (American spelling), also commonly known as a micron, is an SI derived unit of length equalling 1×10−6 metre (SI standard prefix “micro-” = 10−6); that is, one millionth of a metre (or […]

Do volcanoes cause lightning? Volcanic lightning arises from colliding, fragmenting particles of volcanic ash (and sometimes ice), which generate static electricity within the volcanic plume, leading to the name dirty thunderstorm. Moist convection and ice formation also drive the eruption plume dynamics and can trigger volcanic lightning. What does volcanic earthquake mean? A volcano tectonic […]

What are the embryological evidence that we all have a common ancestry? They provide good evidence for natural selection. Examples of evidence from embryology which supports common ancestry include the tail and gill slits present in all early vertebrate embryos. What is the evidence of embryology? The study of one type of evidence of evolution […]

Is there a ball that can bounce forever? The law of conservation of energy implies that a bouncing ball will bounce forever. Of course, it does not. When you drop it on the floor, it changes some of its energy into other forms, such as heat, each time it hits the floor. What are bouncy […]

When a force is applied on a body it may change its? A force applied on an object can change its state of rest or motion and its shape or size. What are the three laws of motion class 9? In the first law, we come to understand that an object will not change its […]

What is the main goal of Gestalt therapy? Gestalt therapy seeks to resolve the conflicts and ambiguities that result from the failure to integrate features of the personality. The goal of Gestalt therapy is to teach people to become aware of significant sensations within themselves and their environment so that they respond fully and reasonably […]
