Answer: Diffusion
Explanation:
Diffusion is the process or a spontaneous movement of particles from an area of higher concentration to an area of lower concentration.
Examples are;
1. perfume
2. A drop of ink in a cup of water.
From these two examples when it is dropped, especially ink, it diffused inside the entire space of the cup and fill all the space by penetrating the entire molecule of the water available.
Answer:
Organelles
Explanation:
Living cells of organisms contain structures within them that perform specific functions for the cell. These structures are called ORGANELLES. Organelles are organ-like structures that are specific about their function in a cell.
Both the cells of prokaryotes and eukaryotes possess organelles, however, the organelles in eukaryotes are bounded by a membrane e.g mitochondrion, chloroplast etc. while those of prokaryotic cells are not bounded by a membrane.
The organelles inside a cell can be seen with the aid of an electron microscope. Examples of organelles are chloroplast (functions in photosynthesis), mitochondria (functions in production and storage of cellular energy), ribosome (functions in protein synthesis) etc.
Answer:
True
Explanation:
Hostility can be explained in clear terms as a form of emotion portrayed in an aggressive manner, which is unfriendly and an arousal of anger from within as a result of denial or rejection.
Coronary heart disease occurs when major blood vessels that supply blood,oxygen,and nutrients to the heat becomes damaged. It major cause are inflammation or cholesterol deposits in the arteries that supply all these nutrients, oxygen and blood to the heart. This causes coronary arteries to narrow, limiting blood flow to the heart. It is said that some slight modifications to care for coronary heart disease include a better lifestyle changes,socialization etc, but when an individual susceptible to coronary heart diseases is hostile, it endanger the effect of such individual more to chronic effects.
Hostility levels is also related as a better predictor of coronary heart disease risk than factors such as high cholesterol, high blood pressure etc. This is because more heart attacks are attributed to anger than high cholesterol.
Answer:
Generalization
Explanation:
In classical conditioning, generalization refers to the ability of an organism to respond to a stimulus the same way it responds to a stimulus that is similar. For example, generalization is seen in Pavlov’s experiment with dogs, after the pairing of the meat powder with the tone of a bell. The dog which naturally salivates as an unconditioned response to the meat powder (unconditioned stimulus), also later produce similar response (conditioned response) when presented only with the sound of a bell (conditioned response). This is generalization in classical conditioning, as the dog responds in a similar way to meat powder and also to the tone of a bell.
