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>
That would be A. Photosynthesis.
<span>This behavior is an example of B. overproduction. The frog lays thousands of eggs, which is much more than it needs, or would need in perfect conditions. However, most of those eggs doesn't survive, and little frogs are never born in that case. This is why it has to have a lot of eggs so as to ensure that a decent number of offspring survives so as to continue the species.</span>
Answer:
19.32L
Explanation:
Given parameters:
Volume of the gas at STP = 29.3liters;
Using this information first, let us find the number of moles of the gas.
Number of moles = 
With the number of moles, we can further solve this problem;
Number of moles = 
= 1.31 moles
More parameters;
Pressure on gas = 1.39atm
temperature = -23°C = -23 + 273 = 250K
Unknown:
Volume of gas = ?
Solution:
The ideal gas equation is the perfect fix to solve this problem.
It is mathematically expressed as;
Pv = nRT
where P is the pressure
v is the volume
R is the gas constant
n is the number of moles
T is the temperature
Input the parameters;
1.39 x V = 1.31 x 0.082 x 250
V = 19.32L
