The epithelial cells resist stretching and twisting in the
skin because if desmosomes that holds them together. The desmosomes are the one
responsible for the cell to cell adhesions, making them be tight or held
together as this is its structure.
<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>
Answer:
Which of the following equations are balanced correctly?
2Ag2O → 4Ag + O2
Zn + HCl → ZnCl2 + H2
Cu + H2O → CuO + H2
2C4H10 + 13O2 → 8CO2 + 10H2O
Explanation:
Proteins are unbranched polymers constructed from 22 standard α-amino acids.
The protein show four levels of structural organisation; the primary structure, secondary structure, tertiary structure and quaternary structure.
The structure of proteins are stabilized by peptide bonds between the amino acid and hydrogen bond between the peptide chainds.
The primary structure of a protein is determined by the sequence of amino acids, but secondary and tertiary structures of protein define their natural or native conformation.
The solubility of protein varies according to the pH, ionic strength, nature of solvent, temperature etc.
Proteins can be classified as simple proteins or conjugated proteins on the basis of their composition.
The proteins can also be classified as fibrous proteins or globular proteins on the basis of their shape.
Proteins play a major part in body structure and function as most of the molecules like antibodies, immunoglobulins, hemoglobin, myoglobin ,most of the enzymes are proteins.
So proteins are also called building blocks of the body.
