Brain loses 5 to 10% of its weight between the
ages of 20 and 90. One study found that the volume of the brain was 15% less in
older adults than in younger adults. On average, the brain loses 5% to 10% of
its weight between the ages of 20 and 90 years; brain volume also decreases.
A class of lipids used as chemical messengers, to signal cells to undergo changes, is called Monoglycerides. Its a class of glycerides which are composed of molecules of glycerol linked to fatty acid by easter bond.
Monoglycerides are the type of glyceride and that made up of glycerol and one fatty acid chain. Triglycerides are very similar expect they have three fatty acid chains. Mono and diglycerides may be manufactured through the reaction of plant or animal derived fatty acids with glycerol which breakdown plant or animals which derived fats and oils.
Lipids such as steroid hormones that serve as chemical messengers between cells , tissues and organs and other communicate signals between biochemical system within a single cell.

Answer:
B) The mass of the reactants equals the mass of the products,
Explanation:
Given that the reaction is balanced, the mass of the reactants must equal to the mass of the products.
We know this by virtue of the law of conservation of mass.
The law of conservation of mass states that "in a chemical reaction, matter is neither created nor destroyed but atoms are rearranged".
Therefore, if the reaction is chemically balanced, the mass of reactants must be the same as the mass of the products in the reaction.
The second choice is the right one.
Answer:
B matter not created destroyed bonds are
The second law describes the relationship between force, mass and acceleration; like Force (Newtons) equals Mass Time Acceleration. Newton's first law defines inertial reference frame as that reference frame where an object will move with constant velocity if no forces are acting on point mass.
Hope this helps you =)
