TRUE. A true-breeding organism, sometimes also called a purebred, is an organism that always passes down certain phenotypic traits to its offspring.
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.

I'm almost positive it's B (<span>B. It must be compacted and/or cemented</span>, but it's been along time since this subject..... Hope this helped.
Gene mutations that result in cancer often cause the cells to divide uncontrollably. When too many cells are made to quickly it develops into a tumor which usually leads to cancer.<span />
