Explanation:
A group of similar cells that perform a particular function is called a tissue. Each cell type has special features that enable it perform a particular function efficiently. Each cell is highly specialized. groups of such specialized cells are normally assembled together to form a tissue which performs a specific function like the epithelial tissue, muscular tissue.
An environmental change is occurring due to continents shifting and moving to different parts of the earth’s surface is a long term change due to tectonic plates movements. if this happends for the continously then there will be different sesonal changes .

Explanation:
Answer:
45 g of the solid Tris will be dissolved in 2.5 liters of water.
Explanation:
Recall that:
<em>Number of moles = molarity x volume</em>
Hence, number of moles of Tris present in 2.5 liters, 150 mM solution:
= 150/1000 x 2.5 = 0.375 moles
Also, recall that:
<em>No of moles of substance = mass/molar mass.</em>
Hence, mass of 0.375 moles substance:
= no of moles of the substance x molar mass of the substance.
= 0.375 x 120 = 45 g.
Therefore, in order to prepare 2.5 liters, 150 mM of an aqueous solution of Tris, 45 g of the solid Tris will be dissolved in 2.5 liters of water.
