Answer: <em>D. Causes an accumulation of lipids in brain cells</em>
Explanation:
Tay-Sachs disease is caused by a genetic mutation in the <em>HEXA</em> gene. It is an autosomal recessive disease that causes the mutation on an enzyme, which metabolizes <em>GM2 Ganglioside</em> in nerve cells, this leads to a build-up of the molecule in brain cells. At the moment there is no cure for the disease, only support treatment is available.
Answer:
Plants need water and sun to create their food source, glucose. When the plant was left in the closet it didn't have access to the sun. One of the requirements of life is that all living things need energy/have a metabolism. Without food the plant eventually died.

The chart very nicely lays out the amino acid each codon corresponds to. You're looking for "trp" in the chart, which only appears once, beside the UGG codon. Therefore, only one codon codes for tryptophan.
<span>A. Acquired traits can be passed to offspring
Jean-Baptiste Lamarck first presented his Theory of Inheritance of Acquired Characteristics in 1801. According to his theory, if an organism changes in order to adapt to its environment, the changes are passed on the organism's offspring. Some of his proposed ideas in the theory, however, were dismissed by other scientists by experimenting and studying of genetics.</span>
