The treatment of gout involves managing the acute inflammatory stage, preventing flare-ups, and controlling hyperuricemia. select the agent of first choice when an acute inflammatory attack begins. colchicine aloprim anturane benemid

Answers

I think the best agent of choice in this case is Colchicine. Gouts is a form of  arthritis caused by excess uric acid in the bloodstream. The symptoms are due to the formation of uric acid crystals in the joints and the body's response to them. Colchicine along with indomethacin, ibuprofen, or a corticosteroid is prescribed to relieve an acute attack of gout. Benemid and Anturane increase the urinary excretion of uric acid, and Aloprim breaks down purines before uric acid is formed.

Answers

Out of the flowing given choices;

A) post-transcriptional processing.

B) electroporation.

C) post-translational processing.

D) nucleic acid hybridization.

E) restriction fragment ligation.

The answer is A. Bacteria do not have a complex post-transcriptional processing tool such as the one in eukaryotes cells.

The attraction of water molecules to other kinds of molecules is called

Answers

Adhesion is the attraction of water molecules to other molecules of different substances.  Water molecules are said to be polar which means that the molecule has a slightly negative charge and a slightly positive charge. This property of water allows it to interact with other polar or charges substances making it attract to other molecules. 

Adhesion is the attraction of water molecules to other kinds of polar molecules, which occurs due to hydrogen bonding formed because of water's polarity, creating interactions with hydrophilic substances.

The attraction of water molecules to other kinds of polar molecules is known as adhesion. This phenomenon occurs because water molecules are polar, which means they have a partial positive charge on the hydrogen atoms and a partial negative charge on the oxygen atom. As a result of water's polarity, each water molecule can form hydrogen bonds with other polar molecules or ions, leading to this adhesive attraction. This forms the basis for many of water's unique properties, such as its ability to dissolve various substances, creating hydrophilic (water-loving) interactions. In contrast, molecules that do not mix well with water, such as oils, are described as hydrophobic (water-fearing).

Where are the proteins of the electron-transport chain located in chloroplasts?

Answers

electron transport chain is found in the inner mitochondrial membrane where it serves as the site of oxidative phosphorylation through the use of ATP synthase. It is also found in the thylakoid membrane of the chloroplast in photosynthetic eukaryotes.

The proteins of the electron-transport chain in chloroplasts are located in the thylakoid membrane, where they play a key role in the light-dependent reactions of photosynthesis.

The proteins of the electron-transport chain in chloroplasts are located in the thylakoid membrane. Chloroplasts capture the energy of light, where the water is split and oxygen is released during the light-dependent reactions of photosynthesis. The electron-transport chain is part of this process, where electrons are transferred through a series of redox reactions, extracting energy to form NADPH and to pump protons across the membrane, generating a proton motive force that drives ATP synthesis. The thylakoid membrane provides the necessary environment for these reactions, housing the electron-transport chain and other crucial components such as Photosystem I (PSI) and Photosystem II (PSII).

In eukaryotes, the electron transport chain in chloroplasts operates similarly to its counterpart in the mitochondria, though they are located in different structures within the cell. Both are essential for ATP production, though they differ in their initial source of electrons; in chloroplasts, the initial electrons come from the splitting of water molecules.

A patient with a history of cirrhosis tells the nurse that his abdomen seems to be getting larger and that he has gained 9.7 kg (20 lb) in the last 6 months. how will the nurse determine whether the abdominal enlargement is from accumulation of fluid or fat from the weight gain?

Answers

There are choices for this question namely:

A. by listening for a fluid wave
B. by percussing the abdomen for shifting dullness
C. by auscultating for lymph nodes
D. by stroking the abdomen to elicit the abdominal reflex

The correct answer is "by percussing the abdomen for shifting dullness". In a patient with liver cirrhosis, there is decreased production of the protein albumin which therefore decreases the plasma oncotic pressure which promotes the leakage of plasma to interstitial tissues as well as in the peritoneum. Excess fluid in the peritoneum is called ascites. By percussing the abdomen for shifting dullness, fat and fluid can be differentiated as dullness in fat remains static and dullness in fluid "shifts".

What is the trna anticodon that binds to the codon you typed above?

Answers

The complementary bases on the codon and anticodon are held together by hydrogen bonds, the same type of bonds that hold together the nucleotide in DNA. The ribosome only allows the tRNA to bind to the mRNA if it is carrying an amino acid. This takes place during the process of translation, where the bases of the anticodon form complementary base pairs with the bases of the codon by forming the appropriate hydrogen bonds.

What is the difference between an epistatic gene and a hypostatic gene? an epistatic gene is dominant; a hypostatic gene is recessive. an epistatic gene produces only two phenotypes; a hypostatic gene produces four phenotypes. an epistatic gene masks the effects of another gene; a hypostatic gene is masked by the epistatic gene. an epistatic gene enhances the effects of another gene; a hypostatic gene reduces the effects of another gene. an epistatic gene masks the effects of another gene when the epistatic gene has one or more dominant alleles; a hypostatic gene masks the effects of another gene when the hypostatic gene has two recessive alleles?

Answers

Final answer:

Epistasis is an interaction between genes where one gene masks or interferes with the expression of another gene. The epistatic gene masks the effects of the hypostatic gene, and this can happen through dominant alleles or two recessive alleles. Phenotypes can be affected by the interaction between these genes, leading to a different number of phenotypes than usual.

Explanation:

Epistasis is an interaction between genes where one gene masks or interferes with the expression of another gene. The gene that does the masking is called the epistatic gene, while the gene being masked is called the hypostatic gene. Epistatic genes can have dominant alleles that mask the effects of the hypostatic gene, while hypostatic genes can be masked when they have two recessive alleles. The interaction between epistatic and hypostatic genes can affect the expression of phenotypes in different ways, such as producing fewer or more than the usual number of phenotypes.

What type of cells is yogurt and cheese made out of?

Answers

dairy cells..........

Final answer:

Yogurt and cheese are made from bacterial cells, particularly from Lactobacillus, Bifidobacterium, and Streptococcus species. These prokaryotic cells ferment milk sugars into lactic acid, causing milk proteins to denature and form yogurt and cheese.

Explanation:

The type of cells used in the production of yogurt and cheese are bacterial cells. These products are typically made using prokaryotic cells, specifically from bacteria such as Lactobacillus, Bifidobacterium, and Streptococcus species. These bacteria ingest the natural sugars found in milk and release lactic acid as a waste product. The accumulation of lactic acid causes the proteins in the milk to denature and form into either a viscous, semi-solid mass for yogurt or a solid mass for cheese.

Yogurt specifically is produced by fermenting milk with strains of bacteria such as Lactobacillus bulgaricus and Streptococcus thermophiles. These bacteria are rod-shaped (bacilli) and often arranged in pairs or short chains. Cheese, on the other hand, has been traditionally made by fermenting milk with a variety of bacteria and sometimes molds, depending on the type of cheese being produced. This process not only enhances the flavor but also preserves the milk, as fermentation products like yogurt and cheese tend to be more stable and less prone to spoilage.
