Use the model to explain how celiac disease interrupts the normal transportation of energy and other nutrients from the digestiv
IrinaK [193]

Answer:

According to the model, the "villi" of small intestines is being damaged as an impact of celiac disease. Small intestines are responsible for absorption of nutrients and minerals from food, this occurs through villi, in case of damaged villi absorption is interfered, thus disturbing the digestive system. If the nutrients, minerals or vitamins are not being absorbed well by small intestines then they will be excreted out of the body and will not be transported to the blood and other areas, this would result in deficiency of minerals and vitamins  in blood that cause weakness.

Most fungi grow best at pH<br> a. 1<br> b. 5<br> c. 7 <br> d. 9<br> e. 14
scZoUnD [109]

Answer: pH 5 Acidic environment.

Explanation:

The fungi grows best in the acidic environment, this is because the fungi grows in a moist, warm and darker environment.

The fungus grows at lower pH. When the fungal species was grown in the laboratory conditions then under low pH, the fungal species grow more properly.

Hence, the best environment for the growth of fungus is pH 5.

You are a researcher working on a treatment for Hutchinson-Gilford progeria syndrome, an extremely rare genetic disorder that ca
Alexus [3.1K]

Answer:

If predominantly, we can't say of any treatment for progeria, aside from the routine observation of heart and blood vessel (cardiovascular) disease which is important in taking care of the health situation in the affected kids. Treatment relies majorly on the situation and clinical manifestations of the kid. At first, in 1999, the findings of the initial clinical drug trial for kids with an unusual rapid-aging disease, often referred to as Progeria, revealed positive results with a farnesyltransferase inhibitor (FTI), a drug initially designed to treat cancer.

The PATHWAY in gene expression to be TARGETED is progenin formulation---

The Progeria-forming mutation results in the formation of the protein progerin that disrupts the cell activities. Some areas of progerin's toxic impact on the body is due to the formation of a farnesyl group, Â that adheres to the progerin protein aiding it's disruption of the body's cells. FTIs means of action is through inhibition of the adhesion of the farnesyl group to progerin, decreasing the hazardous substances that leads to progerin.

The genetic medicine technique that acts as.an intervention tool gene therapy to regulate the gene that causes the stimulation and formation of the protein progenin.

Escalated cardiovascular disease results in death in the case of Progeria.

It's worthwhile to note that if the basic blood vessels can with time get better as a result of treatment, the treatment shows positive results. Slowing down stroke and aging manifestations will boost the chances of treatment.

The light reactions require the cooperation of 2 photosystems to power linear electron flow from h2o to NADP+.?
Iteru [2.4K]

Answer:

Only Photosystem I  - 1, 5, 6

Only photosystem II - 3, 2

Both Photosystem I and II   - 4

Explanation:

Only Photosystem I  

a) Reduction of NADP+ -  uses light energy to convert NADP+ to NADPH2

b)  Reduction of electron transport chain between the two photosystems

c) Oxidation of electron transport chain between the two photosystems.

Only photosystem II

a)  Oxidation of water - here the absorbed light energy is used to dissociate of water molecules to produces protons (H+) and O2 along with free ions

b)Reduction of primary electron acceptor - An electron is taken by pheophytin which is a primary electron acceptor molecule that is  located within photosystem II and hence it get reduced.

Both Photosystem I and II  

a) Light is absorbed in both photosystem I and II. While in photosystem I, light waves of large wavelength i.e 700 nm are absorbed, in photosystem II light waves of short wavelength of i.e 680 nm are absorbed.
