If the amount of daylight increases plant growth, then plants will have higher rates of growth during the summer. hypothesis.
The outer layer of the Earth is divided into plates that move due to convection currents under the surface. theory
For every action or force in nature, there is an equal and opposite reaction. law
A hypothesis is a scientific conjecture, not verified that requires corroboration. It is a possibility, but not a fact. A hypothesis must express what is expected to occur in a perfectly comprehensive manner. There must be a logical relation between variables. It must be objective. The researcher suggests a hypothesis in order to predict what is going to happen. There are different kinds of hypotheses: descriptive, correlative, differentiative, or causative.
A law is an affirmation based on repeated experimental observations, it is not that might describe one aspect of a natural phenomenon. This means that it is corroborated by facts, and not only by logic. There is a relation cause-effect.
The scientific theory is a conceptual framework used to explain facts or phenomena and to make predictions. The theory is fundamental to science because it allows scientists to organize and understand observations. The construction of a theory begins with a hypothesis. The scientist believes that a certain phenomenon occurs in a certain way and so he/she performs observations under the scientific method to prove that his/her hypothesis is valid or not valid. The systematization of the observations as well as of the empirical data collected might derive in a scientific theory that can explain the analyzed phenomenon. A scientific theory is a knowledge that was contrasted in several ways.
A mature erythrocyte lacks nucleus and mitochondria so as to make a place for the accommodation of more hemoglobin and hence more oxygen molecules. Lack of such organelles also provides the peculiar biconcave appearance of RBCs that aids in efficient diffusion. Young mammalian RBCs are nucleated.
