The drugs that interfere with the disassembly of a SNARE complex are capable of blocking neurotransmission because the SNARE complex is responsible for the exocytotic release of neurotransmitters.
<h3>What is neurotransmission?</h3>
Neurotransmission is defined as the transfer of information as electrical impulses from one nerve cell to another.
The chemicals that helps in the neurotransmission are called the neurotransmitters.
The SNARE complex are a group of protein family that is responsible for the release of neuroticism from the neural vesicles.
Therefore, the drugs that interfere with the disassembly of a SNARE complex should be capable of blocking neurotransmission.

It's the amalyse that digested the food or starch in out mouth. Amalyse is an enzyme that is responsible to break down the starch in to sugar. Usually, it is present in our saliva, this is where the digestion started then next to our stomach.
I believe that local controls are what causes reactive hyperemia to increase tissue perfusion. Reactive hyperemia or venous hyperemia is the transient increase in organ blood flow that occurs following a brief period of ischaemia.
Tissue perfusion is the decrease in oxygen resulting in the failure to nourish the tissues at the capillary level. Local blood flow regulation involves the rapid control of arterial vasomotion based on the metabolic needs of the surrounding tissues and cells.

First, i m going to explain how the disease is inherited.
Like it says in the question, hemophilia's gene is carried on the X chromosome and is recessive.
Females inherit two X chromosomes, one from each parent. They are: XX
Males inherit one X chromosome from their mother and a Y chromosome from their father. They are XY.
I'll represent with Xᵃ- when the chromosome has the disease's gene and with only an X when that chromosome is normal.

If Joe has hemophilia is because the X chromosome that was inherited from the mother, came with the disease. Since men only have one X chromosome, the gene will be expressed.
However, this doesn't mean that the mother had the disease, she could be only a carrier with this genotype: XᵃX
(there is not enough information to be sure which one is she)

Maternal grandmother- COULD HAVE INHERITED
Like i said before, Joe's mother had a least one X chromosome with the disease's gene, and that came from either her father or her mother( joe's Maternal grandmother).
If it came from the grandfather, that means that he was hemophilic.
If it came from the grandmother, that means that she was a carrier or also had the disease. There is not enough info to be sure which genotype she has but either way, there is a possibility.

Maternal grandfather- COULD HAVE INHERITED
Joe's mother had a least one X chromosome with the disease's gene, and that came from either her father( maternal grandfather) or her mother.
If it came from the grandfather, we can be certain he was hemophilic.He had the same genotype as joe which is: Xᵃ Y
5-
Paternal Grandmother and Paternal Grandfather- COULD NOT HAVE INHERITED.
In x-linked recessive diseases, fathers cannot pass it on to their son because they will pass the Y chromosome, not the X.
Joe's father gave Joe the Y chromosome and will not pass any X.
So, even if Joe's father and his side of the family had hemophilia, that wouldn't matter because either way, Joe will not be receiving any X chromosomes.
Answer:
i have 2 answers if they are both wrong im sorry
Explanation:
Small uncharged polar molecules, such as H2O, also can diffuse through membranes, but larger uncharged polar molecules, such as glucose, cannot. Charged molecules, such as ions, are unable to diffuse through a phospholipid bilayer regardless of size; even H+ ions cannot cross a lipid bilayer by free diffusion.
or
The molecules that cannot pass through the phospholipid bilayer are sugars, +ions, and -ions.
