The symbol on a regulatory marker
that indicates hazards such as rocks or stumps is an Orange Diamond. Regulatory
markers are types of non-lateral markers such as white and orange markings that
are used as navigation aids that give directions, warn of dangers and marks
controlled locations. Orange diamond shapes warns of dangers such as rocks,
stumps or construction.
She tells them that once cells differentiate, they become different from one another and each one become specialized depending on the type of functions it will perform. Differentiation is the process by which cells's structure change and become modify to carry out certain functions. As cells differentiate they become different from one another and cells which are similar in functions come together to form tissues and organs.
Photosynthesis has a role in the cycling of matter and flow of energy into and out of organisms. The flow of energy and cycling of matter can be traced. The chemical reaction by which plants produce complex food molecules (sugars) requires an energy input (i.e., from sunlight) to occur hope this helps :)
It is the process of muscle contraction involving the sliding of actin & myosin myofilaments past each other to shorten the length of each sacromere.
<span>Empirical studies are results of analysis of data based on actual observation or experiences in the field. When conducting an empirical study, quantitative and qualitative approaches are employed, including:</span>
<span>1. </span><span>Providing data</span>
<span>2. </span>Emphasizes features of a new condition
<span>3. </span>Describes the current status of existing condition
<span>4. </span>Highlight associations between variables, but cannot establish causality, and
<span>5. </span>Suggest hypotheses which can be tested in analytical studies
<span>Qualitative empirical studies provide deep contextual data to help us understand a situation, but it cannot be used to establish its prevalence or incidence. It cannot be generalized also to highlight the statistical relationship between variables. If the aim is to measure the relationship, the quantitative methods should be used. A cross-sectional survey with large sample size is needed to describe the who, what, and where of a situation. Still, it cannot answer the why question. In order to answer the question of "why", an analytical or experimental study is needed. Experimental error is an important consideration here considering lapses or inaccuracies in the qualitative and quantitative data. </span>
