Answer:
Fortified
Explanation:
A fortified food is a food to which nutrients have been included into that ordinarily do not contain such nutrients. The inclusion of the additional nutrient is to provide improved nutrition as well as to meet dietary needs. Food drink such as milk products usually contain added vitamin D, which serves as a fortification. Produced fruit juices can sometimes be found fortified with vitamin D.
False- While lymph does not contain red blood cells, it often contains white blood cells.
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.
Answer:
<u>Credentialing</u>
Explanation:
<u>Credentialing</u> is a process for validating the background of healthcare professionals and assessing their qualifications to provide healthcare services in an organization.
In order to maintain a stable internal environment, or homeostasis, the body uses negative and positive feedback. In negative feedback, the body works to correct a deviation from a set point, it tries to get back to normal. Examples include body temperature, blood pressure, blood oxygen levels, and thirst sensation. In positive feedback, the body changes from the normal point and amplifies it. Examples include blood clot formation, lactation, contractions during childbirth, and fever.
