Answer:
All options are correct, that is, they would all be correct for osteoarthritis.
This disease is characterized by being very painful at the joint level, it is degenerative, and mobility decreases over time.
Explanation:
Osteoarthritis is a pathology that is based on the fegenerative destruction of the joints, generating edema and loss of function, that is why it is pain.
The pain is very intense and very marked, that is why it is treated with immunosuppressive drugs and analgesics. (In addition to kinesiology and physiotherapy).
This disease decreases the functional unit and the joint space, generating possible ankylosis, pseudoarthrosis, elimination of lubricating fluid from joints and nodular structures. These nodular structures tend to be more common in the hands and are called by professionals as "drum fingers".
Answer:
Answer is A.
"Lava", "Magma" and "Volcano".
Explanation:
As we should know before now that Volcano occurs when tectonic plates slide against each other.
This rupture on the earth allows hot "lava", and gases to escape from a "magma" vent. All these sum to be a "volcano".
People contribute to <span>antibiotic resistance by not completing their full course of antibiotics as prescribed by doctors when they are sick. This allows the bacteria to adapt to the antibiotic because the incomplete treatment did not kill the bacteria. Another way in which bacteria are becoming resistant to antibiotics is the widespread use of antibiotics in everyday consumer products, such as cleaners and beauty products. These antibiotics end up in the environment, and diluted exposure to these antibiotics by bacteria allows the bacteria to develop a resistance. </span>
Question
Microarrays allow for
•a comparison of expression of different genes under different growth conditions.
• the analysis of global gene expression.
•the hybridization of cDNA (converted from mRNA with DNA affixed to a solid-state support.
• all of the above.
Answer:
• all of the above.
Explanation:
Microarray involves the collection and isolation of genetic samples (DNA) from a sample or tissue.
Microarray is composed of a large number of DNA material that is arrange sequentially for easy identification and use.
Microarray is used to compare the expressions of various types of genes that are growing under different conditions. It can also be used for analysis of genes globally.
Four bands appear in gel electrophoresis. Gel electrophoresis is an experimental method used to separate mixtures of DNA, RNA, or proteins by molecular size.
DNA is negatively charged, so when a current is applied to the gel, the DNA migrates towards the positively charged electrode. Fragments are ordered by size because short DNA strands migrate through the gel faster than long strands. There are some basic steps for performing gel electrophoresis outlined below. 1) pour the gel, 2) prepare the sample, 3) load the gel, 4) run the gel (expose it to an electric field), 5) stain the gel. Gel electrophoresis is a technique for separating biomolecules by size. Separation of these molecules is achieved by placing them in a small pore gel and creating an electric field across the gel
