Answer:
Based on the given information , the cellular structure , which don not function properly in Tay Sachs disease is <u>Lysosomes </u>
Explanation:
<u>LYSOSOMES -:</u> In many animal cells, a lysosome is a membrane-bound organelle. These are spherical vesicles containing hydrolytic enzymes that can break down many types of biomolecules. A lysosome, with both its membrane proteins and its lumenal proteins, has a particular composition. There are a number of enzymes in lysosomes, helping the cell to break down different biomolecules that it swallows, including peptides, nucleic acids, carbohydrates , and lipids (lysosomal lipase). For optimal function, the enzymes responsible for this hydrolysis need an acidic environment.
<u>TAY SACHS DISEASE -: </u>The autosomal recessive disorder Tay-Sachs is caused by mutations in both gene alleles (HEXA) on chromosome 15. HEXA codes for the enzyme β-hexosaminidase A alpha subunit. This enzyme is contained in organelles, lysosomes, which break down large molecules for the cell to recycle.
Normally, β-hexosaminidase A helps to degrade a lipid called ganglioside GM2, but the enzyme is absent or present only in very small amounts in Tay-Sachs individuals, enabling excessive accumulation of ganglioside GM2 in neurons. In the different types of Tay-Sachs, the progressive neurodegeneration seen depends on the speed and degree of accumulation of GM2 ganglioside, which in turn depends on the amount of functional β-hexosaminidase A present in the body.
Hence , the answer is<u> lysosomes .</u>
Gene expression includes two major processes transcription and translation:
Transcription is the process in which RNA nucleotides find their complementary base on the DNA and are joined together to make a single-stranded RNA molecule.
DNA Base RNA Base
C G
G C
T A
A U
Translation - The RNA molecule, generated called messenger RNA or mRNA acts as a messenger to decide which amino acid needs to be added to the peptide chain
. The mRNA contains three-base sequences called codons, which tell the ribosome what specific amino acid needs to be added.

Answer:
C
Explanation:
There are two kinds of water, fresh and salt water. Salt water is found in the ocean, which means that any answer with salt water, or the ocean, in it is not a correct source of freshwater. A, B, and D, all include the ocean as their answer, which means that they all include salt water, so C is the only option left. Lakes, rivers, water vapor, and ice sheets are all examples of sources of freshwater. I hope your sister gets a good grade!
Bacteria, tree, algae, corn, and grass.
Answer:
A.) An organism obtains one allele for a gene of a specific trait from each parent on one chromosome.
