Hunter syndrome is a rare genetic disorder in which large sugar molecules called glycosaminoglycans build up in body tissues. Hunter syndrome causes abnormalities in many organs, including the skeleton, heart, and respiratory system. In severe cases, this leads to death during the teenage years. Hunter syndrome is caused by a recessive gene on the X chromosome. If a woman who is normal (but had a father with the disease) marries a normal man, what are the chances of having a daughter affected by the disease
Answer:
Hunter syndrome is a very rare, inherited genetic disorder caused by a missing or malfunctioning enzyme. In Hunter syndrome, the body doesn't have enough of the enzyme iduronate 2-sulfatase.

What are the major mechanisms of epigenetic genome modification?
The major mechanisms of epigenetic genome modification are DNA methylation, histone modifications, and non-coding RNA-associated gene silencing.
DNA methylation is the process in which there is an addition of methyl groups to the DNA molecule. When there is the presence of methyl groups on a gene , it is turned off. Thus, no protein formation takes place from that gene.
Histone modification is the process in which histone proteins, can be modified by the addition or removal of methyl or acetyl groups. DNA is wrapped around histone proteins, and histone proteins can be modified by the addition or removal of methyl or acetyl groups. Due to these modifications. it affects how tightly DNA is wrapped around histones and genes can be turned off and on.

How does sodium regulate the uptake of glucose into enterocytes?
Answer:
Sodium regulates the absorption of glucose by the enterocytes.
There are two basic types of transport systems for glucose:
- Sodium dependent glucose transporters (SGLTs)
- Glucose transporters (GLUTs)
Sodium is transported into cells actively by SGLTs, and glucose is transported into cells passively. The co-transport system's energy source are the sodium ions. In addition to other tissues, the GI brush-border membrane contains a very high number of SGLTs.
There are as many as 6 more related proteins, mostly expressed in the kidney, and at least 3 SGLTs (SGLT1-3) have been described from different species. The extracellular side of the SGLTs has both N and C terminal ends, totaling up to 15 transmembrane domains.
The GLUTs enable the diffusion of glucose, and some of them can also move other hexose carbohydrates. Due to amino acid sequences in the four hydrophilic domains of the 12 transmembrane domains, certain GLUT proteins are tissue-specific.

Why is it important to homeostatically regulate csf composition independently of the blood?
It is very important to regulate homeostatically Cerebrospinal fluid composition because neurons are not like other cells they requires a unique environment to sustain its function properly. This homeostatic regulation also protects neurons from blood-borne proteins, cells and toxic factors.
Cerebrospinal fluid (CSF) is found in the subarachnoid space that surrounds the brain and spine and ventricles (Shaft-like spaces inside of the brain). The purpose of CSF is to provide nutrients, remove waste, and cushion the brain and spine. It is also important to drain CSF properly as pressure like hydrocephalus results from the gradual blockage of the CSF-draining pathways in the brain, that results in blockage of ventricles thus compressing the brain within and eventually damaging or destroying the brain tissue.

In the marine mollusk, Aplysia, serotonin binds to a G-protein-coupled receptor and activates a Gs subunit. The resulting activation of PKA leads to phosphorylation and closure of K channels. What effect would this have on the cell
The serotonin binds to a G-protein -coupled receptor and activates a G-subunit . This results in activation of PKA and closing of the potassium channels. This will subsequently decrease the influx of potassium ions into the cell, and lead to depolarization of the cell. This changes the membrane potential of the cell.
Aplysia are sea slugs which fall under the category of mollusks. Serotonin is a hormone which is responsible for the transfer of electrical signals from the brain to different parts. In this particular mollusk, serotonin was studied to find that it is an essential neurotransmitter that is responsible for the maintenance of synaptic plasticity in the neurons. Synaptic plasticity is the feature which is essential for the communication of neurons. This is the modification which occurs at the synapses during the transmission of synapses.

Compare the function of phototropism to the function of gravitropism. How does each of
these tropisms work?
(Hint: starch molecules and auxins should be part of your response.)
The function of phototropism can be compared best with the function of gravitropism by taking an example of statoliths (Starch molecules) in roots and auxin in stem.
Roots often bend away from light (i.e., exhibit negative phototropism) in the direction of gravity(i.e. exhibit positive gravitropism).
Whereas stem-like organs drive their growth toward the light (i.e., positive phototropism) and away from gravity (i.e., negative gravitropism) (i.e. positive gravitropism).
As in the instance of phototropism, positive tropisms react by migrating towards the direction of the stimulus source.
Auxin formation and blue light stimulation control this response's mechanism.
On the shaded side of the plant, where those cells are starting to elongate, the activation of the blue light results in a concentration of auxin, a plant hormone.
On the other hand, negative tropisms, like gravitropism in plant shoots, react by migrating away from the stimulus's source.
A unique type of cell called a statocyst contains statoliths, which are starch molecules that can settle within the statocysts in reaction to gravity.
These starch molecules accumulate on the bottom of the statocyst as they descend toward gravity, increasing auxin levels and encouraging cell elongation.
Hence, these two processes can be compared best with an example of statoliths (Starch molecules) in roots and auxin in stem.

INTRODUCTION
The decline in weed seed numbers in arable fields (approx. 95%) over the course of the 20th century is witness to the success of weed control measures (Robinson and Sutherland, 2002). This success in weed control has resulted primarily from the extensive use of herbicides, changes in crop rotations and a range of cultivation methods. However, the sustained use of a range of agro‐chemicals, in recent years, has resulted in an increase in the number of herbicide‐resistant weed species (Powles and Shaner, 2001), a shift in the weed flora of arable fields from one of mixed weeds to one dominated by grass weeds (Barr et al., 1993) and increasing environmental and public health concerns over the use of pesticides (Conway and Pretty, 1991).
