Answer:
The correct answer to the question: Dr. Gonzalez is:___ would be: Checking the validity of his tool to measure depressive symptoms.
Explanation:
Dr. Gonzalez, as a researcher, wants to test a tool that he himself created in order to measure depressive symptoms in Hispanic women. In order to validate his tool, and know if it will give acceptable results, he compares his tool with others than have already been established, and scientifically proven as effective. As such, he not only will ask participants in his study respond to his instrument, but he will also apply one that has already been used with that purpose: the Beck Depression Inventory, and another one that will measure factors not related to depression, known as a social desirability scale. With the results from all three tools, Dr. Gonzalez will be able to ascertain the validity of his own scale, and test it against others. In this way, he is further vaidating his results as well, and showing the accuracy of his own instrument.
Answer: All of the above (I, II, III, IV)
Explanation:
The Insulin receptor is a large protein that binds to insulin and passes its message into the cell. When insulin binds to the receptor, it causes a change in shape that is propagated inside the cell, which results to MAPK activation, which regulates gene expression via Fos, Jun and Myc, PI3K activation leading to an increase in glucose transport, High affinity binding of SH2 domains to phosphorylated tyrosines and Autophosphorylation resulting in activation of tyrosine kinase.
Answer:
there is a white outer covering of the eye known as the sclera
Answer:
Polymerase chain reaction, or PCR, is a technique to make many copies of a specific DNA region in vitro (in a test tube rather than an organism).
PCR relies on a thermostable DNA polymerase, Taq polymerase, and requires DNA primers designed specifically for the DNA region of interest.
In PCR, the reaction is repeatedly cycled through a series of temperature changes, which allow many copies of the target region to be produced.
PCR has many research and practical applications. It is routinely used in DNA cloning, medical diagnostics, and forensic analysis of DNA.
PCR:
Polymerase chain reaction (PCR) is a common laboratory technique used to make many copies (millions or billions!) of a particular region of DNA. This DNA region can be anything the experimenter is interested in. For example, it might be a gene whose function a researcher wants to understand, or a genetic marker used by forensic scientists to match crime scene DNA with suspects.
Typically, the goal of PCR is to make enough of the target DNA region that it can be analyzed or used in some other way. For instance, DNA amplified by PCR may be sent for sequencing, visualized by gel electrophoresis, or cloned into a plasmid for further experiments.
PCR is used in many areas of biology and medicine, including molecular biology research, medical diagnostics, and even some branches of ecology.
