Answer:
Hmm.
Explanation:
Measles is so contagious that if one person has it, up to 90% of the people close to that person who are not immune will also become infected. Infected people can spread measles to others from four days before through four days after the rash appears.
Answer:
Abstract
Down syndrome (DS) is associated with aberrations in genetic, morphological, biochemical and physiological characteristics. A number of genes located on human chromosome 21 (HSA21) encode proteins which are thought to be involved in numerous metabolic pathways, e.g., phosphofructokinase, cystathionine β-synthase etc. Perturbations of the metabolic pathways may lead to altered drug metabolism in DS individuals. We present a review of metabolic aberrations linked to HSA21 genes in DS. We particularly focus on drug disposition, efficacy, sensitivity and toxicity of anti-leukaemic agents including methotrexate, glucocorticoids, anthracyclines and cytarabine in DS leukaemia. The different outcomes of therapy due to differential drug response, varied drug toxicity and treatment related mortality in DS leukaemia is a subject of much research and speculation. Altered drug response in DS individuals may stem from differences in pharmacokinetics, pharmacodynamics and pharmacogenetics. Further large-cohort studies in different age groups dissecting metabolic and molecular pathways involved in drug response may increase our understanding in this regard and stipulate pharmacotherapies in DS.
If a scientist is studying an infectious agent in a lab, it is very important to understand the implications of evolution because then the scientist will be able to predict how the agent will adapt to different hosts.
Answer:
receive the sound and then filtration of the messages to avoid confusion.
Explanation:
Active listening process is into five stages: 1) receiving the message, 2)understanding, 3)remembering 4) evaluating the selected message, and 5) response to the message.
Receiving is the first stage of the listening skill which involves the hearing of the message and then filtration of the message. The hearing of the message involves the focused attention while filtration of the message involves the isolation of the message from a mixture of messages. The filtration is performed to avoid the mixing of the stimuli.
Thus, receive the sound and then filtration of the messages to avoid confusion is the correct answer.
