Answer:
Through simple diffusion, down the concentration gradient.
Explanation:
The phospholipids of the membrane are amphipathic with hydrophillic heads and hydrophobic tails. Other polar molecules cannot go through this hydrophobic interior. Since small uncharged lipids are non polar and hydrohobic, they are able to go through the membrane without the help of transport proteins. Therefore, the last two options can be ruled out because facilitated diffusion includes the use of a protein. Diffusion involves molecules moving down the concentration gradient so the second option can be ruled out.
Answer:
Its is a lysosomal storage disease!
Explanation:
<u>Hurler syndrome:-</u> is also known as mucopolysaccharidosis-I .
It Is due to the mutation on chromosome 4 .
There is a lack of of enzyme called alpha-L-iduronidase.This enzyme is present in lysosomes
It causes accumulation of mucopolysaccharides because of the absent of the enzyme in the lysosome
<u>Hunter syndrome:- </u>is also known as mucopolysaccharidosis-II
It occurs due to mutation in iduronate-2-sulfatase (IDS) gene.It is an X-linked disease
It would be major depending on the interval but also minor so true
