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>
initially as temperature increases rate of photosynthesis increases, but after reaching on climax, due to scarcity of water, it starts to decrease

Answer:
Liza bought things that had little packaging. She practised conservation through this as the less packaged items would not have been sold and hence would have gone to waste.
Liza did not use a plastic bag to put her bought items. Instead, she used her backpack. In this way, she practised conservation by not using a plastic bag. Also, plastic bags are hard to dispose of and are not degradable.
