Within multicellular organisms, tissues are organized communities of cells that work together to carry out a specific function. The exact role of a tissue in an organism depends on what types of cells it contains. For example, the endothelial tissue that lines the human gastrointestinal tract consists of several cell types. Some of these cells absorb nutrients from the digestive contents, whereas others (called goblet cells) secrete a lubricating mucus that helps the contents travel smoothly.
However, the multiple cell types within a tissue don't just have different functions. They also have different transcriptional programs and may well divide at different rates. Proper regulation of these rates is essential to tissue maintenance and repair. The spatial organization of the cells that form a tissue is also central to the tissue's function and survival. This organization depends in part on polarity, or the orientation of particular cells in their place. Of course, external signals from neighboring cells or from the extracellular matrix are also important influences on the arrangement of cells in a tissue.
Answer:
d. NaOH Sodium hydroxide soluble
Answer:
The correct option is Malachite which has both copper nd oxygen.
Explanation:
As we the symbol of copper is Cu while the symbols of oxygen is O. As the chemical formula of malachite is Cu₂CO₃(OH)₂. So it has Cu as well as O.
Glucose has only oxygen but no copper
Chalcopyrite has copper but no oxygen
Calcite has oxygen but no copper.
So correct answer is only malachite.

Answer:
Hydrophobic amino acids
Explanation:
Hydrophobic amino acids are the amino acids which do not reside in the aqueous environment. These amino acids are generally buried within hydrophobic core of protein or the protein fold or lie in lipid portion of membrane.
Hydrophobic, as the term implies - hydro means water and phobic means fearing. These amino acids have little or almost no polarity in side chains. This lack of polarity make them water fearing.
