Answer:
28.2%.
Explanation:
Attack rate of any pathogen describes the speed or morbidity by which the new or emerging population is at risk by the attack of the pathogen.
The attack rate can be calculated by the formula:
Attack rate = people affected or at the risk of infection / Total population.
65 people are affected and 72 people also shows the symptoms.
Attack rate = 65 + 72 / 485
Attack rate = 137 / 485
Attack rate = 0.28.
The attack rate percent = 0.28 × 100 = 28%.
Hence, the answer is 28%.
I’m going to go with both are true
Answer:
Okay
Explanation:
Human topoisomerase I plays an important role in removing positive DNA supercoils that accumulate ahead of replication forks. It also is the target for camptothecin-based anticancer drugs that act by increasing levels of topoisomerase I-mediated DNA scission. Evidence suggests that cleavage events most likely to generate permanent genomic damage are those that occur ahead of DNA tracking systems. Therefore, it is important to characterize the ability of topoisomerase I to cleave positively supercoiled DNA. Results confirm that the human enzyme maintains higher levels of cleavage with positively as opposed to negatively supercoiled substrates in the absence or presence of anticancer drugs. Enhanced drug efficacy on positively supercoiled DNA is due primarily to an increase in baseline levels of cleavage. Sites of topoisomerase I-mediated DNA cleavage do not appear to be affected by supercoil geometry. However, rates of ligation are slower with positively supercoiled substrates. Finally, intercalators enhance topoisomerase I-mediated cleavage of negatively supercoiled substrates but not positively supercoiled or linear DNA. We suggest that these compounds act by altering the perceived topological state of the double helix, making underwound DNA appear to be overwound to the enzyme, and propose that these compounds be referred to as ‘topological poisons of topoisomerase I’
The client who must be placed in airborne precautions is the client with a positive PPD (purified protein derivative) who has a positive x-ray for a suspicious tuberculin lesion.
Airborne precautions are steps that healthcare ability callers and stick need to attend when going into or leaving a patient's range. Airborne carefulness is for cases where one has a beginning that can spread through the air. They help stop beginning from extending so additional society forbiddance vomit.
PPD is a test used to discover if you have infection contamination. It will not cause infection contamination. This cure can be secondhand for different purposes; request your health management wage earner or druggist if you have questions. The purified protein derivative is an irritant (an essence that excites the invulnerable structure to remove or fight external entities in the party), that is introduced under the skin in the radius. After 48 to 72 hours the dose section is judged by a surgeon.

Answer:
A) bind to receptors in the nucleus of their target cells.
Explanation:
Steroid hormones are synthesized from cholesterol and are lipids, therefore they cannot be transported in the blood dissolved in the plasma. They are associated with transport proteins to travel in blood.
Because they are lipids, they can diffuse through cell membranes, and once inside the target cell they bind to receptors in the cytoplasm or the nucleus and alter gene expression.
